Abstract

Background In clinical practice and in research, aphasia measurement instruments are used for many reasons: to screen and diagnose, to identify deficits and strengths, and to measure outcomes. A proliferation in available measurement instruments presents challenges to both the aphasia clinician and researcher and forms a barrier to optimal practice. There is a need for a comprehensive review of measurement instruments to identify the diversity of constructs measured by available tools and their cultural and linguistic applicability to the international aphasia community. Aims (1) To identify all available standardised measurement instruments which have been developed or tested with people with aphasia; and (2) To describe the construct/s measured, method of report, structure (components and scoring system), and availability of cultural/linguistic adaptations, of identified instruments. Methods and Procedures This scoping review is reported in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Studies were identified through searches of PUBMED, EMBASE, and CINAHL databases. Secondary searches of individual measurement instruments and hand searching were also undertaken. Two reviewers independently assessed titles, abstracts, and full-text articles. Inclusion criteria: studies reporting psychometric properties of measurement instruments, participants with aphasia (or their proxies), English language full-text journal articles. Data extracted: purpose, structure, and method of report of each instrument. The construct(s) reported to be measured by each instrument was classified according to the International Classification of Functioning, Disability and Health (ICF). Outcomes and Results A total of 3642 articles were identified through database searches. Following the removal of duplicates, 2879 articles were screened by title and abstract; with 334 articles undergoing full-text review. Secondary searches of individual measurement instruments and hand searching identified a further 99 publications. In total, 284 references for 143 measurement instruments were included in this review. Measurement instruments were classified by ICF component; the majority were reported to be measures of Body Functions (n = 94); followed by Activity/Participation (n = 23); Environmental Factors (n = 5); and quality of life/other constructs not within the ICF (n = 16). Five measured multiple ICF components. Conclusions and Implications This review identified 143 measurement instruments, developed or tested with people with aphasia. Classified according to the ICF, these instruments primarily measure Body Functions (n = 94). Some measurement instruments have undergone extensive cultural and linguistic translation/adaptation, however most have not. The resulting corpus of instruments provides a basis for the selection of measurement instruments in clinical and research settings.

... therefore, data were synthesised by icAP. For outcome measurement questions, outcome measures were categorised using the icF domains using a recently published scoping review [40]. As previously noted, synthesis was done on study type with only experimentally designed studies answering RQs 4-6. ...
... Data from 21 papers answered this question. Measures were categorised according to icF domain following a recently published scoping review [40]. categorisation was performed by the first author and ratified by the full authorship team. ...
... therefore, we categorised the cAt as a "comprehensive language test" under "body functions". Additionally, the scoping review [40] did not categorise discourse measures. Discourse measures were allocated to icF domains in the current study as three authors (Mc, JM, lD) have authored a systematic review on discourse treatments in aphasia [71]. ...

Purpose: This study synthesizes participant and outcome data from peer-reviewed Intensive Comprehensive Aphasia Programme (ICAP) studies. Methods: A systematic review was conducted following PRISMA guidelines. Study eligibility criteria were specified in relation to population, intervention, comparison, outcome, and design considerations. Data were extracted according to six research questions. Narrative synthesis was used. Results: Twenty-one studies were included covering 13 ICAPs (N = 485, aged 18-86 years, between 11 and 335 months post-stroke). Twenty-seven participant selection criteria were identified. Fifty-six outcome measures spanning the WHO-ICF were used, with the majority assessing the body function domain. Only eight studies employed an experimental design with data appropriate for analysis and synthesis. Risk of bias was noted across this sub-group. Participants improved in word-finding, communication, activity/participation, and communication-related quality of life, and maintained their gains; however, except for word finding, evidence of effect came from isolated studies. Factors influencing outcomes were rarely considered. Some drop-outs, missed sessions, and fatigue were noted. Some studies reported IPD alongside group analyses. Conclusions: ICAP selection criteria need justification and should contribute to the understanding of candidacy for this treatment model. Rationalisation of ICAP treatment content and outcome measurement is required, spanning all WHO-ICF domains. Employment of the core outcome set for aphasia would enable data synthesis and facilitate comparisons between the ICAP and other therapy models.
... They are smart as before and can think clearly but struggle to express or understand language. Unfortunately, persons with aphasia tend to be depressed and frustrated about their situation which makes them lose confidence and choose to be isolated from others [3][4]. They can no longer do their daily normal activities that they usually used to enjoy and become too tiring for them in communicating with others, as it requires a lot of effort. ...
... The rehabilitation is given to enhance communication skills of aphasic patients for social participations. But the needs of each patient differ a lot depending on the severity and reception of the illness; thus, the choice of therapy is most likely personalized and that undergone detailed assessment [3,[5][6]. Augmentative and Alternative Communication (AAC) assisted treatments promotes social participations since it is a straightforward substitute for linguistic deficits. It is known for its positive emotional effect on patients that prevents them from isolating themselves due to their condition. ...
... With the observance of computer technology on the different treatments, many patients also improved their communication skills beyond the use of these devices as an aid since it lets them practice to linguistic skills. But there is still a tendency for them to depend fully on the device therefore, the use of this communication aids must be studied and systematically applied in treatments [3]. ...
Conference Paper
Stroke is one of the primary causes of aphasia in the world. This deficit doesn't include their ability to think but, their lack of way to communicate degrades an aphasic patient's personhood. Speech-language therapy is the known treatment for aphasia. The different levels of severity and personal acceptance of patients greatly contribute to the complexity of treatment application. These factors challenge the general approach of speech and language therapy for aphasia rehabilitation. One factor that greatly solve this challenge is social engagement, but this approach becomes limited to lower severe cases where they have better capability to exercise their communication skills even outside treatment. The use of Augmentative and Alternative Communication devices was established to promote significant improvements of linguistic skills in aphasic patients, but AAC devices are not accessible to most patients and aphasia clinicians and researchers are not experts in the field of its working technology. This study developed an augmentative and alternative communication (ACC) device with materials that are market-available and with open-source software for device manipulation. These contributes to removing the barrier of limited help of technology for treating aphasia. The ACCstive Touchpad were made with the basic necessary features that an ACC device must have such as personalized bank of word and phrases that they could use outside of therapy. With the string and speech tests made with aphasic patients, the devices were concluded to be user-friendly. While with the character test, aphasic patients could decide if they would desire a keyboard with more buttons.
... This agreement represents an initial threshold of clinically meaningful change on our anchor-rating scales. Scores from OMIs are crucial to monitoring and improving services, and ultimately outcomes for people with aphasia [10,35]. Therefore, establishing MIC values must be considered an important progression in aphasia outcome measurement. ...
... This observation is reflective of OMIs more broadly, as patient-reported, performance-based and clinicianrated OMIs measure distinct information from each other. Although combining these data is valuable, no single measure captures sufficient information to understand the impact of aphasia on a person [13,35]. Accordingly, clinicians should exercise caution in using any single OMI to measure aphasia outcomes. ...

Introduction Outcome measurement instruments (OMIs) are used to gauge the effects of treatment. In post‐stroke aphasia rehabilitation, benchmarks for meaningful change are needed to support the interpretation of patient outcomes. This study is part of a research programme to establish minimal important change (MIC) values (the smallest change above which patients perceive themselves as importantly changed) for core OMIs. As a first step in this process, the views of people with aphasia and clinicians were explored, and consensus was sought on a threshold for clinically meaningful change. Methods Sequential mixed‐methods design was employed. Participants included people with post‐stroke aphasia and speech pathologists. People with aphasia were purposively sampled based on time post‐stroke, age and gender, whereas speech pathologists were sampled according to their work setting (hospital or community). Each participant attended a focus group followed by a consensus workshop with a survey component. Within the focus groups, experiences and methods for measuring meaningful change during aphasia recovery were explored. Qualitative data were transcribed and analysed using reflexive thematic analysis. In the consensus workshop, participants voted on thresholds for meaningful change in core outcome constructs of language, communication, emotional well‐being and quality of life, using a six‐point rating scale (much worse, slightly worse, no change, slightly improved, much improved and completely recovered). Consensus was defined a priori as 70% agreement. Voting results were reported using descriptive statistics. Results Five people with aphasia (n = 4, > 6 months after stroke; n = 5, < 65 years; n = 3, males) and eight speech pathologists (n = 4, hospital setting; n = 4, community setting) participated in one of four focus groups (duration: 92–112 min). Four themes were identified describing meaningful change as follows: (1) different for every single person; (2) small continuous improvements; (3) measured by progress towards personally relevant goals; and (4) influenced by personal factors. ‘Slightly improved’ was agreed as the threshold of MIC on the anchor‐rating scale (75%–92%) within 6 months of stroke, whereas after 6 months there was a trend towards supporting ‘much improved’ (36%–66%). Conclusion Our mixed‐methods research with people with aphasia and speech pathologists provides novel evidence to inform the definition of MIC in aphasia rehabilitation. Future research will aim to establish MIC values for core OMIs. Patient or Public Contribution This work is the result of engagement between people with lived experience of post‐stroke aphasia, including people with aphasia, family members, clinicians and researchers. Engagement across the research cycle was sought to ensure that the research tasks were acceptable and easily understood by participants and that the outcomes of the study were relevant to the aphasia community. This engagement included the co‐development of a plain English summary of the results. Advisors were remunerated in accordance with Health Consumers Queensland guidelines. Interview guides for clinicians were piloted by speech pathologists working in aphasia rehabilitation.
... Furthermore, the burden on PWA and rehabilitation providers was considered, and the experts made a subjective decision [11]. The point is that selecting an objective assessment scale for PWA is currently difficult [12]. As a result, there is a risk that speech-language pathologists and clinicians will miss important information that can be used to develop an appropriate rehabilitation plan for PWA and accurately measure the effectiveness of that rehabilitation. ...
... Therefore, it can be useful in planning effective PWA rehabilitation and subsequent research. Although reviews refer to the assessment items in the screening tests for language function with stroke [10], the comprehensive assessment tests for language function, and the assessment tests for aphasia [8,12], there has been no review of accuracy. Furthermore, no such review studies exist in Japan. ...

Aphasia nearly affects half of all poststroke patients. Furthermore, aphasia affects all language functions, well-being, and quality of life of patients. Therefore, rehabilitation of patients with aphasia requires an accurate assessment of language function and psychological aspects. However, assessment scales for language function and psychological aspects of patients with aphasia are said to be inaccurate. In Japan, this sign is more prominent than in English-speaking countries. Therefore, we are putting together a scoping review of research articles published in English and Japanese to date, with the aim of summarizing the accuracy of rating scales for language function and psychological aspects of people with aphasia. The scoping review was intended to be a comprehensive examination of the accuracy of rating scales for people with aphasia. We will search the article databases PubMed, MEDLINE, Embase, PsycINFO, Web of Science, and the Medical Journal Web (Japan). The observational studies that describe the reliability and validity of the rating scales in adult aphasic after stroke will be searched for. There will be no publication date for the articles that will be searched. We believe that this scoping review aims to assess the accuracy of rating scales used to measure different aspects of aphasia, with a focus on research conducted in English-speaking countries and Japan. By conducting this review, we believe to identify any problems with rating scales used in English and Japanese research and improve their accuracy.
... In terms of assessing functional independence in everyday communication activities, a range of psychometrically sound aphasia measures exists (Wallace et al., 2020). For example, the following OMIs tap into communication activities or functional communication: Amsterdam Nijmegen Everyday Language Test/ANELT (Blomert et al., 1994), The Scenario Test (van der Meulen et al., 2010), Communicative Effectiveness Index/CETI (Lomas et al., 1989), Communication Outcome after Stroke (COAST) scale (Long et al., 2008), Communication Activities of Daily Living-Third Edition/CADL-3 , and the Aphasia Communication Outcome Measure/ACOM (Hula et al., 2015). ...
... After identification of the mutually agreed upon treatment outcomes across the four stakeholder groups, an additional consensus process was initiated to select the most appropriate psychometrically robust OMIs for each of these six top treatment outcomes. This consensus was based on a scoping review of aphasia OMIs (Wallace et al., 2020) and an aphasia expert consensus meeting incorporating the most highly published aphasia treatment researchers in the Web of Science database. ...

Background Treatment success is the desired outcome in aphasia rehabilitation. However, to date, there is a lack of consensus on what defines a 'successful' result on a given aphasia outcome measurement instrument (OMI). Aim In this methodological paper, we present strategies for how to define and measure treatment success on a given OMI at the group-level, as well as for an individual person with aphasia. The latter is particularly important when research findings from group studies are clinically implemented for individuals in rehabilitation. Scope We start by presenting methods to calculate the average statistically significant change across several (group) studies (e.g., standardised mean difference, raw unstandardised mean difference) for a given OMI. Such metrics are useful to summarise the overall effect of the intervention of interest, particularly in meta-analyses. However, benchmarks based on group effects are not feasible for assessing an individual participant’s treatment success and thus for determining the proportion of patients who had a beneficial response to therapy (overall response rate of an intervention). We therefore recommend a distribution-based approach to determine benchmarks of a statistically significant treatment response at the individual level, i.e., the 'smallest detectable change' for a given OMI, which refers to the smallest change that can be detected by the OMI beyond measurement error. However, the statistical significance of an individual treatment effect does not necessarily correspond to its clinical impact. This requires an additional indicator. The benchmark to determine a clinically relevant improvement on a given OMI is the 'minimal important change'. The minimally important change is defined as the smallest OMI change score perceived as important by the relevant stakeholder group (i.e., people with aphasia, their relatives/caregivers, clinicians). It therefore requires relating the individual OMI change scores to 'anchors', i.e., meaningful external criteria, preferably based on patient-perceived therapy success. Currently, there is no consensus regarding the optimal 'anchors' and their respective definition of clinically important change in aphasia outcome research. Conclusions/Recommendations Operationalising individual treatment success based on both statistically significant and (patient-reported) clinically meaningful benchmarks is a key priority in aphasia rehabilitation. Availability of such measures will (a) facilitate estimates of therapy response rate in intervention studies and thus optimise therapeutic decisions and (b) provide stakeholder groups (e.g., the society, the stroke team, people with aphasia, family, clinicians, healthcare professionals) with objective, statistically reliable and meaningful feedback on individual treatment response in the clinical setting.
... A growing literature describes PROMs as an important component of patient ownership and self-advocacy in health care (Fung & Hays, 2008), including in the communication disorders disciplines (e.g., Cohen & Hula, 2020;Irwin, 2012;Ross, 2006;Wallace et al., 2020). Patient-reported outcome measures are usually written questionnaires that require adequate literacy skills and cognitive abilities to understand and respond to measure questions. ...
... Several PROMs have been designed for PWA (Irwin, 2012;Wallace et al., 2020). For example, the Assessment for Living with Aphasia (ALA; Simmons-Mackie et al., 2014) assesses activity, participation, and quality of life in PWA using graphics, simple language, and administrative supports. ...

Purpose Patient-reported outcome measures (PROMs) for persons with aphasia (PWA) are commonly used to measure various outcomes. Persons with aphasia commonly present with language deficits that can likely increase respondent burden. Elements that contribute to respondent burden include readability, design, and formatting methods. The aims of this study were to determine how PROMs for PWA rate in level of respondent burden and on readability levels. Method Irwin's 2012 review of PROMs for PWA was used for inclusion criteria and additional PROMs developed after 2012 were identified. This method resulted in 14 PROMs, which were rated on proposed respondent burden criteria and also underwent a readability analysis. Results Six PROMs achieved a 7 or higher with the proposed 10-point respondent burden measure, indicating lower respondent burden. Eight PROMs met the nationally recommended reading level of sixth grade. Conclusions Results indicated that the several PROMs available for PWA fail to minimize respondent burden.

Background The Aachen Aphasia Test (AAT) is still the main test in use for the evaluation of aphasic deficits in German-speaking individuals (Huber et al., 1983, 1984). The test has also been adapted to the Italian language (Luzzatti et al., 1996) and was administered to 384 people with aphasia (PWA) almost exclusively after left-hemisphere brain damage (plus 24 individuals with residual symptoms and 8 without aphasia) and 88 control individuals. The study of construct validity and reliability, as well as norm data, were based on those 343 PWA who passed the preliminary examination for applicability of the Token Test. Aims Motivated by current calls for improving the quality of outcome measures in aphasiology, we re-analyzed the psychometric properties of the Italian version of the AAT (IT-AAT) in an enlarged participant sample, and, for key analyses, with more recent psychometric methods. The overall sample comprised 674 PWA (plus 89 individuals with left-brain damage, including 60 individuals with residual aphasic symptoms and 29 individuals without aphasia). The investigation of construct validity, reliability, and extended norm data was based on the subset of 598 PWA who passed the AAT Token Test inclusion criterion. Main Contributions Assessment of construct validity, differential validity, and reliability aspects corroborated the earlier test properties. The extended norm data applied to the performance of an exemplary PWA yielded unanimous assignment to a Wernicke-type aphasia at initial assessment, which evolved, after speech-language therapy, to an impairment pattern consistent with conduction aphasia, characterized by disproportionately poorer performance in subtest Repetition than in subtest Comprehension. Significant improvement could be demonstrated for all subtests, which remained reliable even after taking into account the average expected increase in scores due to spontaneous recovery. Conclusions The psychometric properties and the enlarged normative sample size are well suited for a valid application of diagnostic psychometric single-case analysis procedures to individual patients’ AAT performance profiles and their comparison to detect changes in performance over time.

For a more comprehensive review of PROMs, we encourage readers to review Cohen and Hula (2020) and for adapting PROMS to increase accessibility and readability for people with aphasia to review Engelhoven et al. (2022). Additionally, Wallace et al. (2022) have a scoping review of measurements for people with aphasia that include PROMs that target participation. As examples, we have selected two PROMs that can be used to support PBI in people with aphasia. ...

Purpose Participation is an integral focus of services to people with aphasia and is considered best practice within the scope of practice for speech-language pathology. The Life Participation Approach to Aphasia encourages meaningful participation in life for people living with aphasia. In theory, providing participation-based services to people with aphasia seems logical; however, embedding these constructs of participation into practice can be challenging for speech-language pathologists (SLPs). Project-based intervention (PBI) provides an authentic opportunity to target participation and support identity reformulation in aphasia intervention. Historically, projects have been provided primarily in group-based settings, which may be difficult for the majority of SLPs who primarily offer individual sessions due to reimbursement. This tutorial provides a framework for using PBI in individual sessions for clients with aphasia using five evidence-based components: (a) shared decision making, (b) patient-reported outcomes, (c) goal setting, (d) the project, and (e) ongoing evaluation. Evidence-based tools and a case example are provided to support each component. Conclusions Projects and PBI provide tangible means of placing participation at the center of intervention while also providing opportunities to target language impairments, identity reconstruction, and various environments in a meaningful and personalized way. Projects can be scaled to the client's needs and abilities as well as to the constraints and options of the service delivery setting.
... Unanimous agreement on this item likely reflects the recognition that highquality aphasia care is contingent on identification and referral. Although there are many aphasia screening tools [40,41], most are designed for administration by a speech pathologist. A brief screening tool that can be administered by the multidisciplinary team is needed to support the early identification of communication impairment and appropriate and timely referral to speech pathology services. ...

Background Currently, there are no agreed quality standards for post‐stroke aphasia services. Therefore, it is unknown if care reflects best practices or meets the expectations of people living with aphasia. We aimed to (1) shortlist, (2) operationalise and (3) prioritise best practice recommendations for post‐stroke aphasia care. Methods Three phases of research were conducted. In Phase 1, recommendations with strong evidence and/or known to be important to people with lived experience of aphasia were identified. People with lived experience and health professionals rated the importance of each recommendation through a two‐round e‐Delphi exercise. Recommendations were then ranked for importance and feasibility and analysed using a graph theory–based voting system. In Phase 2, shortlisted recommendations from Phase 1 were converted into quality indicators for appraisal and voting in consensus meetings. In Phase 3, priorities for implementation were established by people with lived experience and health professionals following discussion and anonymous voting. Findings In Phase 1, 23 best practice recommendations were identified and rated by people with lived experience (n = 26) and health professionals (n = 81). Ten recommendations were shortlisted. In Phase 2, people with lived experience (n = 4) and health professionals (n = 17) reached a consensus on 11 quality indicators, relating to assessment (n = 2), information provision (n = 3), communication partner training (n = 3), goal setting (n = 1), person and family‐centred care (n = 1) and provision of treatment (n = 1). In Phase 3, people with lived experience (n = 5) and health professionals (n = 7) identified three implementation priorities: assessment of aphasia, provision of aphasia‐friendly information and provision of therapy. Interpretation Our 11 quality indicators and 3 implementation priorities are the first step to enabling systematic, efficient and person‐centred measurement and quality improvement in post‐stroke aphasia services. Quality indicators will be embedded in routine data collection systems, and strategies will be developed to address implementation priorities. Patient and Public Contribution Protocol development was informed by our previous research, which explored the perspectives of 23 people living with aphasia about best practice aphasia services. Individuals with lived experience of aphasia participated as expert panel members in our three consensus meetings. We received support from consumer advisory networks associated with the Centre for Research Excellence in Aphasia Rehabilitation and Recovery and the Queensland Aphasia Research Centre.
... There is a need to establish rigorous psychometric data for existing clinical measures and within the development of new measurement instruments [59]. Additionally, eliciting feedback and insights from clinicians, clients and family members in the development of outcome measures will improve the relevance of clinical tools to practice [60,61]. ...

Purpose: To identify clinician-perceived barriers and facilitators to the delivery of outcome measurement and evidence-based treatment practices and integration of these practices in aphasia rehabilitation. Materials and methods: Using a convergent mixed methods design, aphasia clinicians (n = 87) across care settings in the United States completed an online survey designed within the Theoretical Domains Framework (TDF). Participants responded to open-ended questions and rated Likert scale statements. Qualitative data were analyzed using content analysis and quantitative data were summarized using descriptive statistics. Results: Factors related to the TDF domain of "environmental context and resources" (priority and productivity demands; characteristics of resources) were cited as primary barriers in 70% of qualitative responses for both outcome and treatment practices and were consistent with Likert rating statements. Facilitators were associated with TDF domains of "memory, attention, decision-making" (decision-making processes), "knowledge" (awareness of evidence) and "social influences" (client and caregiver preferences). Conclusions: Organizational-level factors and the misalignment of the research evidence with clinical needs are barriers to delivering evidence-based care in aphasia rehabilitation. Theoretically informed strategies such as establishing organizational infrastructure for practice change, developing clinically relevant evidence through research-practice partnerships, and implementing algorithms to support clinical decision-making can address barriers and leverage facilitators.

Background: Although people with aphasia (PwA) represent 30% of stroke survivors, they are frequently excluded from stroke research, or their inclusion is unclear. Such practice significantly limits the generalisability of stroke research, increases the need to duplicate research in aphasia-specific populations, and raises important ethical and human rights issues. Objective: To detail the extent and nature of inclusion of PwA in contemporary stroke randomised controlled trials (RCTs). Methods: We conducted a systematic search to identify completed stroke RCTs and RCT protocols published in 2019. Web of Science was searched using terms 'stroke' and 'randomised controlled trial'. These articles were reviewed by extracting rates of PwA inclusion/exclusion, whether 'aphasia' or related terms were referred to in the article or supplementary files, eligibility criteria, consent procedures, adaptations made to support the inclusion of PwA, and attrition rates of PwA. Data were summarised, and descriptive statistics applied when appropriate. Results: 271 studies comprising 215 completed RCTs and 56 protocols were included. 36.2% of included studies referred to aphasia/dysphasia. Of completed RCTs, only 6.5% explicitly included PwA, 4.7% explicitly excluded PwA, and inclusion was unclear in the remaining 88.8%. Among RCT protocols, 28.6% of studies intended inclusion, 10.7% intended excluding PwA, and in 60.7%, inclusion was unclear. In 45.8% of included studies, sub-groups of PwA were excluded, either explicitly (i.e., particular types/severities of aphasia, e.g., global aphasia) or implicitly, by way of ambiguous eligibility criteria which could potentially relate to a sub-group of PwA. Little rationale for exclusion was provided. 71.2% of completed RCTs did not report any adaptations that could support the inclusion of PwA, and minimal information was provided about consent procedures. Where it could be determined, attrition of PwA averaged 10% (range 0-20%). Conclusion: This paper details the extent of inclusion of PwA in stroke research and highlights opportunities for improvement.
... These are numerous. A recent scoping review (Wallace et al., 2022) identified 143 measurement instruments for aphasia across 284 references. Classifying these instruments across the International Classification of Functioning, Disability and Health (ICF; World Health Organisation, 2001), the majority (94) measured Body Function (impairment), 23 measured Activity/Participation, 5 measured Environmental factors and 16 measured quality of life or constructs not specified within the ICF. ...

Background Assessment is an essential part of aphasia management. There are many tools available for aphasia assessment, but relatively scant attention has been paid to how speech pathologists carry out their assessment sessions, or how these sessions are experienced by people with aphasia and their families. The evidence that is available suggests that people with aphasia do not always understand the purposes of the assessments they undertake or receive much useful feedback on their performance. Connections between adult learning and aphasia therapy are being made more explicit, such as through the Life Participation Approach to Aphasia, but the potential for a relationship between adult learning and aphasia assessment has not yet been fully recognised. Aims This paper aims to stimulate thinking to improve current aphasia assessment practices. It uses an adult learning lens and explores theoretical approaches underpinning assessment in adult education contexts. Main Contribution In this commentary paper, we summarise the current, dominant practices around aphasia assessment and then briefly review evidence-based recommended practice for assessment in higher and professional education. We explore useful parallels between the two fields and discuss how we might reassess assessment in aphasia rehabilitation. Conclusions Aphasia assessments have greater potential to be therapeutic than we currently assume. Ideas from adult education are useful to challenge clinicians to reconsider aspects of their practice. Assessments can be a powerful motivator for learning and engagement in therapy. Through a greater focus on formative and sustainable assessment, and changed feedback practices, there are opportunities to capitalise more fully on the potential for learning during these sessions. Attention to the rich development of ideas about assessment in education is a useful way to challenge our assumptions and perhaps prepare our clients with aphasia for a more productive and sustainable learning journey to support their recovery.

People with aphasia have been systematically excluded from stroke research or included without the necessary modifications, threatening external study validity. In this paper, we propose that 1) the inclusion of people with aphasia should be considered as standard in stroke research irrespective of discipline and that 2) modifications should be made to stroke research procedures to support people with aphasia to achieve meaningful and valid inclusion. We argue that outright exclusion of this heterogenous population from stroke research based purely on a diagnosis of aphasia is rarely required and present a rationale for deliberate inclusion of people with aphasia in stroke research. The purpose of this paper is fourfold; 1) to highlight the issue and implications of excluding people with aphasia from stroke research; 2) to acknowledge the current barriers to including people with aphasia in stroke research; 3) to provide stroke researchers with methods to enable inclusion, including recommendations, resources, and guidance; and 4) to consider research needed to develop aphasia inclusive practices in stroke research.
... On the other hand, these tests do not compare individual performance or present error analysis across language modalities. It has to be acknowledged that, the scores obtained from these tests may not hold any direct equivalence to the assessment tools utilized in the Englishspeaking population due to their language-specific nature (Wallace et al., 2020). ...

Background and Aim Cross-linguistic adaptations of aphasia assessment tools in Turkey are needed to improve aphasia assessment and rehabilitation with individuals speaking languages other than well-resourced languages. Aligned with this need, we conducted several studies to propose an adaptation of “The Comprehensive Aphasia Test” (CAT) into Turkish. Methods During this adaptation process; (a) lexical/linguistic and visual stimuli in CAT’s Language Battery subtests were evaluated by examining their imageability, familiarity, and name agreement features through rating studies, and two pilot studies for (b) Cognitive Screening and (c) Language Battery sections were carried out. In the stimuli norming studies, 71 undergraduate students (aged 20–24) rated 236 words in the Imageability and Familiarity tasks; 40 participants (aged 30–60) named 244 pictures in the Name Agreement task. Two sections of the CAT-TR were administered to different groups of subjects with aphasia (PWA) and matched controls. Fourteen PWA (and 14 controls) were presented the Cognitive Screening section, and a different group (PWA = 20, controls = 20) completed the Language Battery section. Results The imageability and familiarity ratings of 236 words and name agreement (% – H statistic) values of 244 pictures were calculated. Imageability and familiarity ratings of the words had a positive strong correlation with each other. Items with a name agreement of 85% or more were considered high name agreement. As anticipated, the control groups both in the Cognitive Screening and the Language Battery sections performed better than the PWA group. As a result, no further adaptive changes were suggested for these sections. Conclusion Results of these studies have shown that the Comprehensive Aphasia Test-Turkish is culturally and linguistically appropriate for Turkish speakers with aphasia. Therefore, future studies should assess its validity and reliability, and establish norms for its clinical interpretation.

Background Aphasia impacts communication and relationships. While counselling is increasingly recognised as a component of the speech‐language therapy role, the success of conversation partner training is typically measured in terms of communication alone. This scoping review aimed to describe how successful conversation is currently measured with couples—with and without aphasia, to inform the development of an ecologically valid measure for couples with aphasia. Methods and Procedures The scoping review was reported in alignment with the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis Extensions for Scoping Reviews (PRISMA‐SCR). MEDLINE, EMBASE, CINAHL and PsycINFO databases were searched for conversation treatment studies for couples with and without aphasia. Patient‐reported outcome measures (PROMs) were extracted from included studies and screened against the three‐tier model of situated language to shortlist those that measure everyday communication. Items within shortlisted PROMs were further described using the refined International Classification of Functioning, Disability and Health linking rules. Results Following screening and full‐text review, 46 studies were included, consisting of 24 studies conducted with couples with aphasia and 22 studies conducted with couples without aphasia. For couples with aphasia, 13 PROMs were identified that measured everyday communication. Of these, 23% were dyadic (i.e., measured from the perspectives of both members of the couple); however, they usually only appraised the communication behaviours of the person with aphasia. For couples without aphasia, eight PROMs were identified that measured everyday communication; all were dyadic and measured both attitudes and communication behaviours of both partners. Conclusion Conversation relies on the interaction of two people, and success in conversation is best rated by those having the conversation. The use of PROMs is recommended as part of person and relationship‐centred practice; however, there is currently no validated PROM for conversation in aphasia that considers the perspectives and behaviours of both the person with aphasia and their communication partner. The PROM items identified in this study will form the basis of future research to develop a PROM for couples' conversations in aphasia. WHAT THIS PAPER ADDS What is already known on the subject Communication partner training (CPT) for couples, where one person has aphasia, can improve conversation skills and enhance relationships. Clinician‐rated measures, such as conversation analysis, have been used to measure the outcomes of CPT. However, there is a lack of person‐centred or self‐rated outcome measurement instruments. that is, patient‐reported outcome measures (PROMs) for couples' conversations in aphasia. What this paper adds to existing knowledge We have identified outcome measurement instruments used in conversation treatment studies for couples with and without aphasia. We found that most PROMs used in aphasia treatment studies were not dyadic, that is, they did not include the self‐report of both communication partners. In contrast, the PROMs used with couples without aphasia were dyadic and contained items that measured a more complex range of both partners' emotions, behaviours and attitudes. What are the potential or actual clinical implications of this work? This study provides insights into the content and characteristics of PROMs for couples' conversation therapy and may assist clinicians in selecting outcome measurement instruments in their practice.

Aphasia research has traditionally been considered a (unidisciplinary) niche topic in medical science. The international Collaboration of Aphasia Trialists (CATs) is a global collaboration of multidisciplinary aphasia researchers. Over the past 10 years, CATs has collectively taken a rigorous approach to systematically address persistent challenges to aphasia research quality. This article summarizes the achievements over the past decade. CATs’ achievements include: standardizing terminology, advancing aphasia research design by aphasia expert consensus recommendations, developing a core data set and intervention descriptors, facilitating the involvement of people with the language impairment aphasia in the research process, translating, and adapting assessment tools into global languages, encouraging data sharing, developing innovative secondary data analysis methodologies and promoting the transparency and accessibility of high quality aphasia research reports. CATs’ educational and scientific achievements over the past 10 years far exceed what individual researchers in the field could have ever achieved.

Background: Evidence-based recommendations for a core outcome set (COS; minimum set of outcomes) for aphasia treatment research have been developed (the Research Outcome Measurement in Aphasia-ROMA, COS). Five recommended core outcome constructs: communication, language, quality of life, emotional well-being and patient-reported satisfaction/impact of treatment, were identified through three international consensus studies. Constructs were paired with outcome measurement instruments (OMIs) during an international consensus meeting (ROMA-1). Before the current study (ROMA-2), agreement had not been reached on OMIs for the constructs of communication or patient-reported satisfaction/impact of treatment. Aim: To establish consensus on a communication OMI for inclusion in the ROMA COS. Methods & procedures: Research methods were based on recommendations from the Core Outcome Measures in Effectiveness Trials (COMET) Initiative. Participants with expertise in design and conduct of aphasia trials, measurement instrument development/testing and/or communication outcome measurement were recruited through an open call. Before the consensus meeting, participants agreed on a definition of communication, identified appropriate OMIs, extracted their measurement properties and established criteria for their quality assessment. During the consensus meeting they short-listed OMIs and participants without conflicts of interest voted on the two most highly ranked instruments. Consensus was defined a priori as agreement by ≥ 70% of participants. Outcomes & results: In total, 40 researchers from nine countries participated in ROMA-2 (including four facilitators and three-panel members who participated in pre-meeting activities only). A total of 20 OMIs were identified and evaluated. Eight short-listed communication measures were further evaluated for their measurement properties and ranked. Participants in the consensus meeting (n = 33) who did not have conflicts of interest (n = 29) voted on the top two ranked OMIs: The Scenario Test (TST) and the Communication Activities of Daily Living-3 (CADL-3). TST received 72% (n = 21) of 'yes' votes and the CADL-3 received 28% (n = 8) of 'yes' votes. Conclusions & implications: Consensus was achieved that TST was the preferred communication OMI for inclusion in the ROMA COS. It is currently available in the original Dutch version and has been adapted into English, German and Greek. Further consideration must be given to the best way to measure communication in people with mild aphasia. Development of a patient-reported measure for satisfaction with/impact of treatment and multilingual versions of all OMIs of the COS is still required. Implementation of the ROMA COS would improve research outcome measurement and the quality, relevance, transparency, replicability and efficiency of aphasia treatment research. What this paper adds: What is already known on this subject International consensus has been reached on five core constructs to be routinely measured in aphasia treatment studies. International consensus has also been established for OMIs for the three constructs of language, quality of life and emotional well-being. Before this study, OMIs for the constructs of communication and patient-reported satisfaction/impact of treatment were not established. What this paper adds to existing knowledge We gained international consensus on an OMI for the construct of communication. TST is recommended for inclusion in the ROMA COS for routine use in aphasia treatment research. What are the potential or actual clinical implications of this work? The ROMA COS recommends OMIs for a minimum set of outcomes for adults with post-stroke aphasia within phases I-IV aphasia treatment research. Although not intended for clinical use, clinicians may employ the instruments of the ROMA COS, considering the quality of their measurement properties. The systematic inclusion of a measure of communication, such as TST, in clinical practice could ultimately support the implementation of research evidence and best practices.

Due to physical and cognitive deficits, it is often difficult and costly for individuals who have suffered a stroke to access on-site neurorehabilitation. Telerehabilitation offers the opportunity to improve the rehabilitation process as it can provide intensive supervised rehabilitation in the home environment. The term telerehabilitation refers to the provision of therapeutic services at a distance, enabled by electronic telecommunication and information technologies. Services are provided through a variety of technical systems with different purposes and capabilities. This chapter provides an overview of technical solutions for providing telerehabilitation services to treat the main consequences of stroke, namely paresis of the upper and lower extremities, and communication difficulties. We describe the communication tools, sensor technologies, virtual reality systems, and robots for service delivery and explore the facilitators and barriers to successful implementation. Evidence is summarized in the context of teleassessment, telemonitoring, and teletherapy.

Purpose This systematic review explored how virtual reality (VR) has been used to rehabilitate aphasia. Materials and methods Empirical studies were included where VR was used to target language, well-being, or quality of life in adults with acquired language impairment. Degenerative communication disabilities were excluded. Seven health databases were searched in October 2021. Risk of Bias was assessed using published checklists and completeness of intervention reporting evaluated. Narrative synthesis described forms of VR, rationales given, outcome measures, communication functions targeted, characteristics of interventions, and outcomes achieved within the framework of impairment, activity, and participation. Results Fourteen studies, involving 229 participants, met the criteria. The studies employed four forms of VR with various rationales given. Interventions used published and novel protocols. Primary outcomes targeted language impairment (12/14), activity (1/14), and well-being (1/14) and achieved positive outcomes in impairment and activity. All studies were exploratory. Risk of bias was high. Findings are discussed in the context of gains achieved by VR in other health contexts and the multi-user gaming literature. Conclusions Uses of VR in aphasia rehabilitation described in the literature are limited. Most applications target the remediation of language impairments. Opportunities to address activity, participation, and wider aspects of well-being are rare. • IMPLICATIONS FOR REHABILITATION • Research documenting the use of virtual reality (VR) to rehabilitate aphasia is limited and exploratory, so does not yet offer clear guidance for clinicians. • Many of the identified studies have used known published protocols (e.g., naming therapy or scripts therapy) delivered through the novel VR format and focus on language impairment outcomes. • VR offers clinicians a unique opportunity to address communication activity and participation through the use of multi-user virtual worlds, but this has only been explored by only two research teams.

Purpose: Motivation is a complex phenomenon that can influence a person's ability to make progress in treatment. We sought to understand how motivation is currently measured and utilized in aphasia rehabilitation by identifying treatment studies that (1) include measurement of motivation and (2) use motivation to predict treatment response. Method: A scoping review was conducted by systematically searching PubMed, CINAHL, EBSCO, Ovid MEDLINE, and APA PsycInfo using the following search terms: (measurement OR treatment OR rehabilitation OR predict*) AND (motiv* OR engagement OR adherence OR compliance) AND (aphasia OR dysphasia). Results: Two studies met our inclusion criteria. Motivation was measured differently across studies. No studies used motivation to predict treatment outcomes. Discussion/conclusions: Despite the importance of motivation in aphasia rehabilitation success, studies that include its measurement are sparse. Additional research is needed and should include development of measurement tools and evaluation of the predictive value of motivation on treatment outcomes.

Purpose: This systematic review aims to identify instruments used to evaluate treatment outcomes for people with spasmodic dysphonia. Methods: Electronic database (PubMed, Cochrane Library, Embase, and CINAHL) searches and hand-searching identified studies that evaluated treatment approaches for spasmodic dysphonia which included pre and post outcome data. Results: A total of 4714 articles were retrieved from searching databases; 1165 were duplicates. Titles and abstracts of 3549 were screened, with 171 being selected for full-text review. During full-text review, 101 articles were deemed suitable for inclusion. An additional 24 articles were identified as suitable for inclusion through hand-searching of reference lists. Data was extracted from 125 studies, identifying 220 outcome measures. As per the World Health Organization's International Classification of Functioning (ICF), the majority measured body functions (n = 212, 96%). Outcomes that explored communication and participation in everyday life and attitudes towards communication (ie, activity and participation domains) were infrequent (n = 8; 4%). Quality of life, a paradigm outside of the scope of the ICF, was also captured by four outcome measures. No instruments evaluating communication partners' perspectives were identified. Conclusions: Currently there is no unified approach to the measurement of outcomes in SD treatment research. Development and implementation of a core outcome set is recommended to facilitate improved understanding of the efficacy of current and new treatment options.

Background: Neuropsychiatric symptoms (NPS) have been insufficiently examined in persons with aphasia (PWA) because most previous studies exclude participants with language and communication disorders. Aim: To report a two-part study consisting of a literature review and an observational study on NPS in post-stroke aphasia. Methods: Study 1 reviewed articles obtained from PubMed, PsycINFO, Google Scholar and Cochrane databases after cross-referencing key words of post-stroke aphasia to NPS and disorders. Study 2 examined language deficits and activities of daily living in 20 PWA (median age: 58, range: 28-65 years; 13 men) with the Western Aphasia Battery-Revised and the Barthel Index, respectively. Informants of these 20 PWA were proxy-evaluated with the Neuropsychiatric Inventory and domain-specific scales, including the Stroke Aphasia Depression Questionnaire-10 item version and the Starkstein Apathy Scale. In addition, an adapted version of the Hospital Anxiety and Depression Scale was directly administered to the PWA themselves. This observational study is based on the baseline assessment of an intervention clinical trial (EudraCT: 2017-002858-36; ClinicalTrials.gov identifier: NCT04134416). Results: The literature review revealed a broad spectrum of NPS in PWA, including depression, anxiety, apathy, agitation/aggression, eating and sleep disorders, psychosis, and hypomania/mania. These findings alert to the need for improving assessment and treatment approaches of NPS taking into consideration their frequent occurrence in PWA. Study 2 showed that the 20 participants had mild- to-moderate aphasia severity and were functionally independent. A wide range of comorbid NPS was found in the post-stroke aphasic population (median number of NPS: 5, range: 1-8). The majority of PWA (75%) had depressive symptoms, followed by agitation/aggression (70%), irritability (70%), anxiety (65%) and appetite/eating symptoms (65%). Half of them also presented symptoms of apathy, whereas euphoria and psychotic symptoms were rare (5%). Domain-specific scales revealed that 45% of participants had apathy and 30% were diagnosed with depression and anxiety. Conclusion: Concurrent NPS are frequent in the chronic period of post-stroke aphasia. Therefore, further research on reliable and valid assessment tools and treatment for this aphasic population is strongly warranted.

Purpose A core outcome set (COS; an agreed minimum set of outcomes) was developed to address the heterogeneous measurement of outcomes in poststroke aphasia treatment research. Successful implementation of a COS requires change in individual and collective research behavior. We used the Theoretical Domains Framework (TDF) to understand the factors influencing researchers' use and nonuse of the Research Outcome Measurement in Aphasia (ROMA) COS. Method Aphasia trialists and highly published treatment researchers were identified from the Cochrane review of speech and language therapy for aphasia following stroke and through database searches. Participants completed a theory-informed online survey that explored factors influencing COS use. Data were analyzed using descriptive statistics and qualitative content analysis. Results Sixty-four aphasia researchers from 13 countries participated. Most participants (81%) were aware of the ROMA COS, and participants identified more facilitators than barriers to its use. The TDF domain with the highest agreement (i.e., facilitator) was “knowledge” (84% agree/strongly agree). Participants had knowledge of the measures included in the ROMA COS, their associated benefits, and the existing recommendations. The TDF domains with the least agreement (i.e., barriers) were “reinforcement” (34% agree/strongly agree); “social influences” (41% agree/strongly agree); “memory, attention, and decision processes” (45% agree/strongly agree); and “behavioral regulation” (49% agree/strongly agree). Hence, participants identified a lack of external incentives, collegial encouragement, and monitoring systems as barriers to using the ROMA COS. The suitability and availability of individual measurement instruments, as well as burden associated with collecting the COS, were also identified as reasons for nonuse. Conclusions Overall, participants were aware of the benefits of using the ROMA COS and believed that its implementation would improve research quality; however, incentives for routine implementation were reported to be lacking. Findings will guide future revisions of the ROMA COS and the development of theoretically informed implementation strategies. Supplemental Material https://doi.org/10.23641/asha.16528524

Background The Oxford Cognitive Screen (OCS) was recently developed with the aim of describing the cognitive deficits after stroke. The scale consists of 10 tasks encompassing five cognitive domains: attention and executive function, language, memory, number processing, and praxis. OCS was devised to be inclusive and un-confounded by aphasia and neglect. As such, it may have a greater potential to be informative on stroke cognitive deficits of widely used instruments, such as the Mini-Mental State Examination (MMSE) or the Montreal Cognitive Assessment, which were originally devised for demented patients. Objective The present study compared the OCS with the MMSE with regards to their ability to detect cognitive impairments post-stroke. We further aimed to examine performance on the OCS as a function of subtypes of cerebral infarction and clinical severity. Methods 325 first stroke patients were consecutively enrolled in the study over a 9-month period. The OCS and MMSE, as well as the Bamford classification and NIHSS, were given according to standard procedures. Results About a third of patients (35.3%) had a performance lower than the cutoff (<22) on the MMSE, whereas 91.6% were impaired in at least one OCS domain, indicating higher incidences of impairment for the OCS. More than 80% of patients showed an impairment in two or more cognitive domains of the OCS. Using the MMSE as a standard of clinical practice, the comparative sensitivity of OCS was 100%. Out of the 208 patients with normal MMSE performance 180 showed impaired performance in at least one domain of the OCS. The discrepancy between OCS and MMSE was particularly strong for patients with milder strokes. As for subtypes of cerebral infarction, fewer patients demonstrated widespread impairments in the OCS in the Posterior Circulation Infarcts category than in the other categories. Conclusion Overall, the results showed a much higher incidence of cognitive impairment with the OCS than with the MMSE and demonstrated no false negatives for OCS vs MMSE. It is concluded that OCS is a sensitive screen tool for cognitive deficits after stroke. In particular, the OCS detects high incidences of stroke-specific cognitive impairments, not detected by the MMSE, demonstrating the importance of cognitive profiling.

Background A systematic review of core outcome sets (COS) for research is updated annually to populate an online database. It is a resource intensive review to do annually but automation techniques have potential to aid the process. The production of guidance and standards in COS development means that there is now an expectation that COS are being developed and reported to a higher standard. This is the fifth update to the systematic review and will explore these issues. Methods Searches were carried out to identify studies published or indexed in 2018. Automated screening methods were used to rank the citations in order of relevance. The cut-off for screening was set to the top 25% in ranked priority order, following development and validation of the algorithm. Studies were eligible for inclusion if they reported the development of a COS, regardless of any restrictions by age, health condition or setting. COS were assessed against each of the Core Outcome Set-STAndards for Development (COS-STAD). Results Thirty studies describing the development of 44 COS were included in this update. Six COS (20%) were deemed to have met all 12 criteria representing the 11 minimum standards for COS development (range = 4 to 12 criteria, median = 10 criteria). All 30 COS studies met all four minimum standards for scope. Twenty-one (70%) COS met all three minimum standards for stakeholders. Twenty-three studies (77%) included patients with the condition or their representatives. The number of countries involved in the development of COS ranged from 1 to 39 (median = 10). Six studies (20%) met all four minimum standards [five criteria] for the consensus process. Conclusion Automated ranking was successfully used to assist the screening process and reduce the workload of this systematic review update. With the provision of guidelines, COS are better reported and being developed to a higher standard.

Aim: Primary aims of this systematic review were to: (1) identify the range of subjective memory measures used in the stroke and stroke-related aphasia literature and (2) critically appraise their psychometric properties as well as (3) the methodological qualities of studies that included them, (4) investigate whether such measures provide an accurate reflection of memory impairments (i.e., in comparison to norms from age-matched, neurotypical participants), (5) document the representation of individuals with stroke-related aphasia, and (6) examine the extent to which subjective memory measures correlate with objective memory measures. Methods: Systematic review of the literature from 1970 to June 2019 using a comprehensive range of relevant search terms in EMBASE, Medline, PsychINFO, SCOPUS, and Web of Science. Eligibility criteria were for studies to include adults who had suffered of clinical stroke, to report a subjective memory measure that was completed by the stroke survivors, to be reported in a peer-reviewed journal, and to be published in English or Dutch. Quality appraisal was carried out for the included studies as well as the subjective memory measures they employed. Results: A total of 7,077 titles or abstracts were screened, with 41 studies included in the quantitative and qualitative synthesis. Twenty-six subjective memory measures were used in the included studies. The critical appraisal of their psychometric properties and the methodological quality of the included studies revealed significant shortcomings; for example, neurotypical participants were included in only 14 of the 41 studies. When statistical comparisons were made, different outcomes arose. Only eight studies statistically compared subjective with objective memory measures. Conclusions: This literature domain currently provides an unclear picture as to how memory limitations affect participation in stroke and stroke-related aphasia. • IMPLICATIONS FOR REHABILITATION • A broad range of subjective memory measures have been used to determine stroke survivors’ perceptions of their everyday memory issues. • Because of psychometric weaknesses such as inadequate reliability and cross-cultural validity among subjective memory measures, there remains a need to carefully review a given measure’s properties to determine if it is appropriate for use with a given stroke survivor. • Stroke survivors with aphasia have been infrequently included or inadequately described in studies of subjective memory measures, and thus how these individuals perceive their everyday memory abilities requires further investigation. • Although the relationship between subjective and objective memory measures has been infrequently investigated by stroke researchers, both types of measures should be considered as they likely offer complementary rather than redundant information about stroke survivors’ memory abilities.

Purpose: To explore the relationship between the two components of spontaneous speech in the Brief Aphasia Evaluation (BAE) and the rest of the scale represented by its three main factors: The Expression, Comprehension, and Complementary factors. Methods: BAE has proven validity and reliability. The evaluation of spontaneous speech in this scale comprises two components: Performance Rank (score: 0-3) and Type of Disorder (Fluency [F], Content [C], or Mixed [FC]) when rank < 3. Sixty-seven patients with left brain damage and 30 demographically matched healthy participants (HP) were studied. It was analyzed the correlation between Performance Rank and the three BAE factors and, recoding 3 as 0 and < 3 as 1, the sensitivity/specificity of this component for each factor. The effect of Type of Disorder on the three factors was analyzed. Results: 1) Performance Rank: Correlations of 0.84 (Expression), 0.81 (Comprehension), and 0.76 (Complementary) were observed, with a sensitivity and specificity ≥ 78% for any factor; 2) Type of Disorder: The performance significantly decreased from FC to C and from C to F in Expression (FC < C < F), from FC to C and from FC to F also in Comprehension and Complementary, from patients with any type of disorder to HP. Conclusion: Performance Rank was a relevant indicator of aphasia by its consistency with valid and comprehensive dimensions of acute language impairments. A degree difference between F and C was observed, being F a milder disorder; i.e., fluency problems were less severe than retrieval or anomia ones.

Objective We sought to (1) identify the outcome measures currently used across stroke arm rehabilitation randomized trials, (2) identify and compare outcomes important to stroke survivors, carers and clinicians and (3) describe where existing research outcome measures capture outcomes that matter the most to stroke survivors, carers and clinicians and where there may be discrepancies. Methods First, we systematically identified and extracted data on outcome measures used in trials within a Cochrane overview of arm rehabilitation interventions. Second, we conducted 16 focus groups with stroke survivors, carers and clinicians using nominal group technique, supplemented with eight semi-structured interviews, to identify these stakeholders’ most important outcomes following post-stroke arm impairment. Finally, we described the constructs of each outcome measure and indicated where stakeholders’ important outcomes were captured by each measure. Results We extracted 144 outcome measures from 243 post-stroke arm rehabilitation trials. The Fugl-Meyer Assessment Upper Extremity section (used in 79/243 trials; 33%), Action Research Arm Test (56/243; 23%), and modified Ashworth Scale (53/243; 22%) were most frequently used. Stroke survivors (n = 43), carers (n = 10) and clinicians (n = 58) identified 66 unique, important outcomes related to arm impairment following stroke. Between one and three outcomes considered important by the stakeholders were captured by the three most commonly used assessments in research. Conclusion Post-stroke arm rehabilitation research would benefit from a reduction in the number of outcome measures currently used, and better alignment between what is measured and what is important to stroke survivors, carers and clinicians.

Aphasia is a devastating brain disorder, detrimental for medical care and social interaction. The early diagnosis of language disorders and accurate identification of patient-specific deficits are crucial for patients’ care, as aphasia rehabilitation is more effective when focused on patient-specific language deficits. We developed the Core Assessment of Language Processing (CALAP), a new scale combining screening and detailed evaluation to rapidly diagnose and identify patient-specific language deficits. This scale is based on a model of language processing distinguishing between the comprehension, production, and repetition modalities, and their different components: phonology (set of speech-sounds), morphology (how the sounds combine to form words), lexicon (words), syntax (how words combine to form sentences), and concept (semantic knowledge). This scale was validated by 189 participants who underwent the CALAP, and patients not unequivocally classified as without aphasia by a speech-language pathologist underwent the Boston Diagnosis Aphasia Evaluation as the gold standard. CALAP-screening classified patients with and without aphasia with a sensitivity of 1 and a specificity of 0.72, in 3.14 ± 1.23 min. CALAP-detailed evaluation specifically assessed the language components in 8.25 ± 5.1 min. Psychometric properties including concurrent validity, internal validity, internal consistency and interrater reliability showed that the CALAP is a valid and reliable scale. The CALAP provides an aphasia diagnosis along with the identification of patient-specific impairment making it possible to improve clinical follow up and deficit-based rehabilitation. It is a short and easy-to-use scale that can be scored and interpreted by clinicians nonexpert in language, in patients with fatigue and concentration deficits.

Objectives The Mississippi Aphasia Screening Test (MAST) is a brief screening tool for assessing the expressive and receptive language abilities of patients with aphasia. The goal of this study was to adapt and validate the MAST into the Estonian language. The discriminant validity and internal consistency of the test were examined, as well as its sensitivity and specificity. Methods The MASTest was administered in 50 left hemisphere stroke patients with aphasia (LHA+ group) in the acute phase after the stroke and 126 healthy volunteers in a control group (CG), stratified by age and level of education. Nonparametric tests were used to get normative values, compare the values of the MASTest scores between the LHA+ group and the CG, and to assess the discriminant validity, internal consistency, sensitivity, and specificity of the MASTest. Results The summary scores: total score (MASTest‐T), expressive score (MASTest‐E), and receptive score (MASTest‐R) correlated with age and educational level, and the normative values were adjusted accordingly. The LHA+ group showed more impairment than the CG in all subtests and summary scores. The internal reliability of the MASTest was high for the whole sample and LHA+ group. The sensitivity and specificity of the MASTest using the 5th percentile were 74% and 94%, respectively, but using receiver operating characteristic (ROC) analysis, it was 89% and 80%. Conclusion The MASTest is a valid screening tool for evaluating expressive and receptive language abilities in Estonian patients with aphasia in early stroke. The MASTest is the first validated aphasia screening test for Estonian‐speaking people, who number less than one million worldwide.

Background Aphasia is a neurogenic communication disorder with significant deficits in various domains of language and communication. One such type of aphasia, which impacts the quality of life significantly is Broca's aphasia, where the individual is aware of the communication difficulty. Objective To compare the Quality of Communication Life (QoCL) between individuals with Broca's aphasia and normal individuals. Methods The first phase of the study translated and validated QCL scale in Tamil. The second phase involved administration of the Tamil QCL scale on 12 individuals with Broca's aphasia and 12 age matched normal adults. The marked responses were analysed on a visual analogue scale independently. Statistical Analysis Three domains of QoCL were compared between the two groups using Mann–Whitney U-test. Results The QoCL scores across three domains were observed to be lower in individuals with Broca's aphasia, when compared to normal adults. Individuals with Broca's aphasia expressed greater challenges in socialization/activities domain of QoCL than confidence/self-concept and roles and responsibilities domains. Conclusions Information obtained on self-reported QCL scale in familiar or native language will facilitate in planning client-oriented management of aphasia.

Background and purpose: Aphasia is a common outcome of stroke affecting one-third of the post-stroke population in China. While the quality of life (QOL) may be affected, care is often inadequately guided due to lack of validated measure for Chinese population with stroke-induced aphasia. This study aimed to develop a Chinese-version of the Stroke and Aphasia Quality of Life-39 generic version (SAQOL-39g) and evaluate its feasibility, reliability, and validity in Chinese patients with stroke-induced aphasia. Methods: The process of translation and adaptation suggested by WHO was used to develop the Chinese-version of SAQOL-39. We evaluated the feasibility, reliability, and validity of the scale in 84 aphasia patients and their proxies by assessing the internal consistency of the test items, test-retest consistency, and the structural validity of data. Results: The self-report and the proxy-report form were completed within 21.4 and 13.3 min on average, respectively. Physical, communication, and psychological subdomains were extracted as three common factors. The Cronbach's alpha coefficients of overall domain and subdomains for both forms ranged from 0.879 to 0.950, indicating high internal consistency. The intraclass correlation coefficients ranged from 0.804 to 0.987 for overall domain and subdomains of the forms. No significant difference was found between two forms. Conclusions: The Chinese-version SAQOL-39g has excellent reliability, validity, and feasibility for measuring the QOL of Chinese post-stroke aphasia patients. The consistency between self-report and proxy-report forms was good, implying that the proxy-report form can be used to assess the QOL of post-stroke aphasia patients.

Background: There are many validated and widely used assessments within aphasiology. Few, however, describe language and life with aphasia from the perspective of the person with aphasia. Across healthcare, patient experience and user involvement are increasingly acknowledged as fundamental to person-centred care. As part of this movement, Patient Reported Outcome Measures (PROMs) are being used in service evaluation and planning. Aims: This paper reports the quantitative aspects of a mixed methods study that developed and validated a concise PROM, the Aphasia Impact Questionnaire (AIQ), co-produced with People with Aphasia (PWA). Methods & Procedures: The AIQ was developed within the social model of disability and all stages of the development of the AIQ were performed in partnership with PWA. It was adapted from a pre-existing and lengthier PROM for PWA, the Communication Disability Profile. The first iterations of the AIQ focused on domains of communication, participation and well-being/emotional state. Subsequently the AIQ was extended to include additional items relating to reading and writing (AIQ-21). The research design was iterative. Initially, concurrent validity, internal consistency, and sensitivity of the AIQ-prototype were obtained. The AIQ-prototype was modified to become the AIQ-21. Statistical testing with a new group of PWA was performed, investigating internal consistency and concurrent validity of the AIQ-21. Outcomes & Results: Results for both the AIQ-prototype and AIQ-21 showed statistically significant concurrent validity and good internal consistency. Repeated measurement using the AIQ-prototype demonstrated statistically significant change after PWA accessed a community intervention. Conclusions: The AIQ-21 is a PROM that has great potential to be one of the core set of aphasia tests for clinical and research use. Results can be used alongside language assessment to enable person-centred goal setting and partnership working for people with aphasia.

Scoping reviews, a type of knowledge synthesis, follow a systematic approach to map evidence on a topic and identify main concepts, theories, sources, and knowledge gaps. Although more scoping reviews are being done, their methodological and reporting quality need improvement. This document presents the PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) checklist and explanation. The checklist was developed by a 24-member expert panel and 2 research leads following published guidance from the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network. The final checklist contains 20 essential reporting items and 2 optional items. The authors provide a rationale and an example of good reporting for each item. The intent of the PRISMA-ScR is to help readers (including researchers, publishers, commissioners, policymakers, health care providers, guideline developers, and patients or consumers) develop a greater understanding of relevant terminology, core concepts, and key items to report for scoping reviews.

Background Discourse in adults with aphasia is increasingly the focus of assessment and therapy research. A broad range of measures is available to describe discourse, but very limited information is available on their psychometric properties. As a result, the quality of these measures is unknown, and there is very little evidence to motivate the choice of one measure over another. Aims To explore the quality of a range of discourse measures, targeting sentence structure, coherence, story structure and cohesion. Quality was evaluated in terms of the psychometric properties of acceptability (data completeness and skewness), reliability (inter‐ and intra‐rater), and validity (content, convergent, discriminant and known groups). Methods & Procedures Participants with chronic mild‐to‐moderate aphasia were recruited from community groups. They produced a range of discourses which were grouped into Cinderella and everyday discourses. Discourses were then transcribed orthographically and analyzed using macro‐ and microlinguistic measures (Story Grammar, Topic Coherence, Local Coherence, Reference Chains and Predicate Argument Structure—PAS). Data were evaluated against standard predetermined criteria to ascertain the psychometric quality of the measures. Outcomes & Results A total of 17 participants took part in the study. All measures had high levels of acceptability, inter‐ and intra‐rater reliability, and had good content validity, as they could be related to a level of the theoretical model of discourse production. For convergent validity, as expected, 8/10 measures correlated with the Western Aphasia Battery—Revised (WAB‐R) spontaneous speech scores, and 7/10 measures correlated with the Kissing and Dancing Test (KDT) scores (r ≥ 0.3), giving an overall positive rating for construct validity. For discriminant validity, as predicted, all measures had low correlations with Raven's Coloured Progressive Matrices (RCPM) and WAB‐R Auditory Verbal Comprehension scores (r < 0.3), giving an overall positive rating for construct validity. Finally, for known groups validity, all measures indicated a difference between speakers with mild and moderate aphasia except for the Local Coherence measures. Overall, Story Grammar, Topic Coherence, Reference Chains and PAS emerged as the strongest measures in the current study because they achieved the predetermined thresholds for quality in terms of each of the psychometric parameters profiled. Conclusions & Implications The current study is the first to psychometrically profile measures of discourse in aphasia. It contributes to the field by identifying Story Grammar, Topic Coherence, Reference Chains and PAS as the most psychometrically robust discourse measures yet profiled with speakers with aphasia. Until further data are available indicating the strength of other discourse measures, caution should be applied when using them.

Background: Reading difficulties often present as a consequence of aphasia. The specific nature of reading deficits varies widely in manifestation, and the cause of these deficits may be the result of a phonological, lexical semantic, or cognitive impairment. Several treatments have been developed to address a range of impairments underlying reading difficulty. Aims: The purpose of this review is to describe the current research on reading comprehension treatments for persons with aphasia, assess the quality of the research, and summarize treatment outcomes. Methods & Procedures: A systematic review of the literature was conducted based on a set of a priori questions, inclusion/exclusion criteria, and pre-determined search parameters. Results were summarized according to treatment type, methodologic rigor, and outcomes. Outcomes & Results: Fifteen studies meeting criteria were identified. A variety of reading comprehension treatments was implemented including: oral reading, strategy-based, cognitive treatment, and hierarchical reading treatments. Quality ratings were highly variable, ranging from 3 to 9 (on a 12-point scale). Overall, 14 of the 18 individuals for whom individual data were provided demonstrated some degree of improvement (oral reading 4/5 participants, strategy based 4/6, and cognitive treatment 6/7). Gains were also evident for hierarchical reading treatment administered to participant groups via computer; however, the degree to which improvement reached statistical significance varied among studies. Conclusions: Reading comprehension treatments have the potential to improve reading comprehension ability in persons with aphasia; however, outcomes were variable within and among treatment methods. We suggest focusing future research on factors such as participant candidacy and treatment intensity using increased methodological rigor.

There is a severe lack of aphasia screening tools for bedside use in Chinese. A number of aphasia assessment tools have recently been developed abroad, but some of these scales were not suitable for patients with acute stroke. The Language Screening Test (which includes two parallel versions [a/b]) in French has been proven to be an effective and time-saving aphasia screening scale for early-stage stroke patients. Therefore, we worked out a Chinese version of the LAST taking into consideration Chinese language and culture. Two preliminary parallel versions (a/b) were tested on 154 patients with stroke at acute phase and 107 patients with stroke at non-acute phase, with the Western Aphasia Battery serving as a gold standard. The equivalence between the two parallel versions and the reliability/validity of each version were assessed. The median time to complete one preliminary Chinese version (each had some item redundancy) was 98 seconds. Two final parallel versions were established after adjustment/elimination of the redundant items and were found to be equivalent (intra-class correlation coefficient: 0.991). Internal consistency is(Cronbach α for each version [a/b] was 0.956 and 0.965, respectively) good. Internal validity was fine: (a) no floor or ceiling effect/item redundancy; (b) construct validity revealed a 1-dimension structure, just like the French version. The higher educated subjects scored higher than their lower educated counterparts (p<0.01). The external validity: at the optimum cut-off point where the score of version a/b <14 in higher educated group(<13 in lower): the specificity of each version was 0.878/0.902(1/1 in lower) and sensitivity was 0.972/0.944(0.944/0.944 in lower). Inter-rater equivalence (intra-class correlation coefficient) was 1. The Chinese version of the Language Screening Test was proved to be an efficient and time-saving bedside aphasia screening tool for stroke patients at acute phase and can be used by an average medical physician.

In neurological patients, a lack of insight into their impairments can lead to possibly dangerous situations and non-compliance in rehabilitation therapy with worse rehabilitation outcomes as a result. This so called anosognosia is a multifaceted syndrome that can occur after brain damage affecting different neurological or cognitive functions. To our knowledge no study has investigated anosognosia for apraxia of common tool-use (CTU) so far. CTU-apraxia is a disorder frequently occurring after stroke that affects the use of familiar objects. Here, we introduce a new questionnaire to diagnose anosognosia for CTU-apraxia, the Visual Analogue Test assessing Anosognosia for Naturalistic Action Tasks (VATA-NAT). This assessment is adapted from a series of VATA-questionnaires that evaluate insight into motor (VATA-M) or language (VATA-L) impairment and take known challenges such as aphasia into account. Fifty one subacute stroke patients with left (LBD) or right (RBD) brain damage were investigated including patients with and without CTU-apraxia. Patients were assessed with the VATA-L, -M and -NAT before and after applying a diagnostics session for each function. Interrater reliability, composite reliability as well as convergent and divergent validity were evaluated for the VATA-NAT. Seven percent of the LBD patients with CTU-apraxia demonstrated anosognosia. After tool-use diagnostics this number increased to 20 percent. For the VATA-NAT, psychometric data revealed high interrater-reliability (τ ≥ 0.828), composite reliability (CR ≥ 0.809) and convergent validity (τ = −0.626). When assessing patients with severe aphasia, the possible influence of language comprehension difficulties needs to be taken into account for interpretation. Overall, close monitoring of anosognosia over the course of rehabilitation is recommended. With the VATA-NAT we hereby provide a novel assessment for anosognosia in patients with CTU-apraxia. For diagnosing anosognosia we recommend to combine this new tool with the existing VATA-M and -L subtests, particularly in patients who demonstrate severe functional deficits.

Background and purpose Accurate aphasia diagnosis is important in stroke care. A wide range of language tests are available and include informal assessments, tests developed by healthcare institutions and commercially published tests available for purchase in pre-packaged kits. The psychometrics of these tests are often reported online or within the purchased test manuals, not the peer-reviewed literature, therefore the diagnostic capabilities of these measures have not been systematically evaluated. This review aimed to identify both commercial and non-commercial language tests and tests used in stroke care and to examine the diagnostic capabilities of all identified measures in diagnosing aphasia in stroke populations. Methods Language tests were identified through a systematic search of 161 publisher databases, professional and resource websites and language tests reported to be used in stroke care. Two independent reviewers evaluated test manuals or associated resources for cohort or cross-sectional studies reporting the tests’ diagnostic capabilities (sensitivity, specificity, likelihood ratios or diagnostic odds ratios) in differentiating aphasic and non-aphasic stroke populations. Results Fifty-six tests met the study eligibility criteria. Six “non-specialist” brief screening tests reported sensitivity and specificity information, however none of these measures reported to meet the specific diagnostic needs of speech pathologists. The 50 remaining measures either did not report validity data (n = 7); did not compare patient test performance with a comparison group (n = 17); included non-stroke participants within their samples (n = 23) or did not compare stroke patient performance against a language reference standard (n = 3). Diagnostic sensitivity analysis was completed for six speech pathology measures (WAB, PICA, CADL-2, ASHA-FACS, Adult FAVRES and EFA-4), however all studies compared aphasic performance with that of non-stroke healthy controls and were consequently excluded from the review. Conclusions No speech pathology test was found which reported diagnostic data for identifying aphasia in stroke populations. A diagnostically validated post-stroke aphasia test is needed.

Background: This study explores the psychometric properties of The Scenario Test UK, a culturally adapted version of the Dutch original (The Scenario Test) developed by van der Meulen et al. in 2010, which evaluates functional, daily-life communication in aphasia. The Scenario Test assesses communication in an interactive context with a supportive communication partner. Aims: To evaluate the reliability (internal consistency, interrater and test-retest reliability) and construct validity (convergent, discriminant and known-groups validity) of The Scenario Test UK. Methods & procedures: The Scenario Test UK and other language, cognition and praxis assessments were administered to persons with aphasia after stroke (3+ months post-stroke) and to non-aphasic controls. Participants were recruited primarily through community stroke groups. Measures were completed in an interview format. Standard psychometric criteria were used to evaluate reliability and construct validity. Outcomes & results: A total of 74 participants with aphasia and 20 participants without aphasia took part in The Scenario Test UK. The test showed high levels of reliability. Internal consistency (Cronbach's α = 0.92), interrater reliability (ICC = 0.95) and test-retest reliability (ICC = 0.96) were excellent. Interrater agreement in scores on the individual items ranged from good to excellent (κ = 0.41-1.00) for all but two items (item 4c κ = 0.38, item 6c κ = 0.36). The test demonstrated good levels of convergent (ρ = 0.37-0.75) and discriminant validity (ρ = -0.04 to 0.23). There was strong evidence for known groups validity (U = 132.50, p < .001), with those with aphasia scoring significantly lower [median (interquartile range-IQR) = 47 (39.8-51.0)] than those without aphasia [53 (52-54)]. Conclusions & implications: The data support the reliability and validity of the Scenario Test UK as an assessment of functional, daily-life communication for persons with aphasia. Further testing is needed in independent samples on the measure's psychometric properties, including its sensitivity to change. Pending this testing, The test can be used as an assessment tool to evaluate communication skills with people with aphasia, to guide goal setting for therapy and to measure outcomes in response to therapy.

This paper describes a quick aphasia battery (QAB) that aims to provide a reliable and multidimensional assessment of language function in about a quarter of an hour, bridging the gap between comprehensive batteries that are time-consuming to administer, and rapid screening instruments that provide limited detail regarding individual profiles of deficits. The QAB is made up of eight subtests, each comprising sets of items that probe different language domains, vary in difficulty, and are scored with a graded system to maximize the informativeness of each item. From the eight subtests, eight summary measures are derived, which constitute a multidimensional profile of language function, quantifying strengths and weaknesses across core language domains. The QAB was administered to 28 individuals with acute stroke and aphasia, 25 individuals with acute stroke but no aphasia, 16 individuals with chronic post-stroke aphasia, and 14 healthy controls. The patients with chronic post-stroke aphasia were tested 3 times each and scored independently by 2 raters to establish test-retest and inter-rater reliability. The Western Aphasia Battery (WAB) was also administered to these patients to assess concurrent validity. We found that all QAB summary measures were sensitive to aphasic deficits in the two groups with aphasia. All measures showed good or excellent test-retest reliability (overall summary measure: intraclass correlation coefficient (ICC) = 0.98), and excellent inter-rater reliability (overall summary measure: ICC = 0.99). Sensitivity and specificity for diagnosis of aphasia (relative to clinical impression) were 0.91 and 0.95 respectively. All QAB measures were highly correlated with corresponding WAB measures where available. Individual patients showed distinct profiles of spared and impaired function across different language domains. In sum, the QAB efficiently and reliably characterized individual profiles of language deficits.

Typically, processing is more accurate and efficient for concrete than abstract concepts in both healthy adults and individuals with aphasia. While, concreteness effects have been thoroughly documented with respect to noun processing, other words classes have received little attention despite tending to be less concrete than nouns. The aim of the current study was to explore concrete-abstract differences in verbs and identify their neural correlates in post-stroke aphasia. Given the dearth of comprehension tests for verbs, a battery of neuropsychological tests was developed in this study to assess the comprehension of concrete and abstract verbs. Specifically, a sensitive verb synonym judgment test was generated that varied both the items' imageability and frequency, and a picture-to-word matching test with numerous concrete verbs. Normative data were then collected and the tests were administered to a cohort of 48 individuals with chronic post-stroke aphasia to explore the behavioural patterns and neural correlates of verb processing. The results revealed significantly better comprehension of concrete than abstract verbs, aligning with the existing aphasiological literature on noun processing. In addition, the patients performed better during verb comprehension than verb production. Lesion-symptom correlational analyses revealed common areas that support processing of concrete and abstract verbs, including the left anterior temporal lobe, posterior supramarginal gyrus and superior lateral occipital cortex. A direct contrast between them revealed additional regions with graded differences. Specifically, the left frontal regions were associated with processing abstract verbs; whereas, the left posterior temporal and occipital regions were associated with processing concrete verbs. Moreover, overlapping and distinct neural correlates were identified in association with the comprehension and production of concrete verbs. These patient findings align with data from functional neuroimaging and neuro-stimulation, and existing models of language organisation.

Objetivo: Estudiar la relación entre la percepción del cuidador sobre el deterioro en el habla espontánea del paciente, según un ítem de cuatro preguntas administradas mediante entrevista semiestructurada, y el desempeño del paciente en la Evaluación Breve de la Afasia (EBA). Método: Se examinaron 102 pacientes diestros, con lesiones cerebrales focales de diferente tipo y localización. EBA es un instrumento válido y confiable para la medida de la afasia. Se correlacionó la percepción del cuidador con el ítem de habla espontánea, la puntuación total y los tres principales factores de EBA: el factor de Expresión, el de Comprensión y el Complementario. Se analizó la precisión (sensibilidad-especificidad) de la percepción del cuidador sobre el habla espontánea del paciente, respecto de la presencia o ausencia de trastorno, según el profesional, en el ítem de habla espontánea de EBA. Resultados: La correlación estudiada fue satisfactoria, siendo mayor (superior al 80%) para los siguientes indicadores: el ítem de habla espontánea, el factor de Expresión y la puntuación total de la escala; la correlación fue un poco menor (superior al 70%) para el factor de Comprensión y el Complementario. Comparando dos puntos de corte que evaluaron la precisión en la percepción del cuidador, se observaron resultados satisfactorios en términos de sensibilidad y especificidad (>70%), con cocientes de probabilidad superiores a 3. Usando la mediana como punto de corte, se obtuvieron discriminaciones diagnósticas más satisfactorias. Conclusión: Entrevistar al cuidador específicamente sobre el habla espontánea del paciente, en forma abreviada, proporciona información relevante para el diagnóstico de la afasia.

Background Nonlinguistic cognitive impairment has become an important issue for aphasic patients, but currently there are few neuropsychological cognitive assessment tests for it. To get more information on cognitive impairment of aphasic patients, this study aimed to develop a new cognitive assessment test battery for aphasic patients, the Non-language-based Cognitive Assessment (NLCA), and evaluate its utility in Chinese-speaking patients with aphasia. Methods The NLCA consists of five nonverbal tests, which could assess five nonlinguistic cognitive domains such as visuospatial functions, attention test, memory, reasoning, and executive functions of aphasic patients. All tests are modified from the nonverbal items of the current existed tests with some changes to the characteristics of Chinese culture. The NLCA was tested in 157 participants (including 57 aphasic patients, 50 mild cognitive impairment (MCI) patients, and 50 normal controls), and was compared with other well-established relative neuropsychological tests on the reliability, validity, and utility. Results The NLCA was fully applicable in the MCI patients and the normal controls, almost working in the aphasic patients (57/62 patients, 91.9%). The NLCA scores were 66.70 ± 6.30, 48.67 ± 15.04, and 77.58 ± 2.56 for the MCI group, the aphasic group, and the control group, respectively, and a significant difference was found among three groups (F = 118.446, P < 0.001). The Cronbach's alpha of the NLCA as an index of internal consistency was 0.805, and the test-retest and interrater reliability was adequate (r=0.977 and r= 0.970, respectively). The correlations of the cognitive subtests and their validation instruments were between 0.540 and 0.670 (all P < 0.05). Spearman's correlation analysis indicated that the coefficient of internal consistency of each subtest itself was higher than other subtests. When choosing the Montreal Cognitive Assessment score of <26 as the diagnostic criteria of cognitive impairment, the area under the curve for all participants in the control and MCI groups was 0.942 (95% confidence interval: 0.895–0.989), and an optimal cutoff point of 75.00 seemed to provide the best balance between sensitivity and specificity. Age (r = −0.406, P < 0.001) was the main influence factor for the NLCA. Conclusions The NLCA could efficiently differentiate the cognitive impairment patients from the normal controls and is a reliable and valid cognitive assessment test battery to specially find nonlinguistic cognitive function for aphasic patients.

Objectives: To validate a non-verbal self-report measure of mood - the Dynamic Visual Analogue Mood Scales (D-VAMS) - against the Hospital Anxiety and Depression Scale (HADS) and assess its suitability as an outcome measure or screening measure for depressed mood following stroke. Design: Cross-sectional observational cohort study. Participants: Forty-six stroke survivors (24% with aphasia) recruited from online, from stroke clubs and via an NHS rehabilitation service. Methods: A set of seven bipolar scales was developed enabling users to report mood by modifying facial expression images using a slider. Participants completed a tablet/computer task, reporting their mood on these scales mixed randomly with versions which used only words. The HADS was then completed, followed by a repeat run of the two versions in a different, random sequence. Results: Exploratory factor analysis identified one factor consistent with pleasantness of mood accounting for 80% of the variance. Internal consistency of D-VAMS was high ( α = 0.95), and there was a high correlation between face-only D-VAMS scores and HADS total scores ( r = -0.80, P < 0.001), as well as HADS-D/HADS-A subscale scores ( r = -0.73, P < 0.001; r = -0.71, P < 0.001). D-VAMS showed good sensitivity and specificity against HADS, with means of 85%/77% (sensitivity/specificity) against the HADS-D and 80%/77% against the HADS-A across nine cut-offs. Conclusion: D-VAMS is a valid and reliable measure likely suitable for assessment of depressed mood in aphasia following stroke. Though D-VAMS performed well as a screening measure in this study sample, further study is needed in the acute stage post-stroke.

Background: Depression is one of the most researched emotional responses after stroke and shows that the emotional impact of aphasia can have a marked negative impact on recovery, response to rehabilitation, and psychosocial adjustment. There is an evident dearth of validated instruments to assess depression in people with aphasia including Hindi, the national language of the country. Aims: The aim of this study was to translate and adapt the original English version of widely used hospital version of Stroke Aphasia Depression Questionnaire (SADQ-10) to Hindi. Subjects and methods: English version of SADQ-10 was translated and adapted for the use in Hindi-speaking population in concordance to the WHO guidelines. Statistical analysis used: The intraclass correlation coefficient (ICC) analysis of the data was performed using SPSS, version 16, to compute the test-retest reliability. Results: The Hindi version of SADQ-10 yielded an overall high test-retest reliability (ICC = 0.91) as well as internal consistency (α = 0.98), which in turn were comparable to the original instrument in English. Conclusions: SADQ10-Hindi may assist the identification of depressed mood in patients with speech and language impairment in an Indian population as well. It is an easy to administer and quick test which can be used by health-care professionals in a hospital- or community-based settings.

A range of methods in clinical research aim to assess treatment-induced progress in aphasia therapy. Here, we used a crossover randomized controlled design to compare the suitability of utterance-centered and dialogue-sensitive outcome measures in speech-language testing. Fourteen individuals with post-stroke chronic non-fluent aphasia each received two types of intensive training in counterbalanced order: conventional confrontation naming, and communicative-pragmatic speech-language therapy (Intensive Language-Action Therapy, an expanded version of Constraint-Induced Aphasia Therapy). Motivated by linguistic-pragmatic theory and neuroscience data, our dependent variables included a newly created diagnostic instrument, the Action Communication Test (ACT). This diagnostic instrument requires patients to produce target words in two conditions: (i) utterance-centered object naming, and (ii) communicative-pragmatic social interaction based on verbal requests. In addition, we administered a standardized aphasia test battery, the Aachen Aphasia Test (AAT). Composite scores on the ACT and the AAT revealed similar patterns of changes in language performance over time, irrespective of the treatment applied. Changes in language performance were relatively consistent with the AAT results also when considering both ACT subscales separately from each other. However, only the ACT subscale evaluating verbal requests proved to be successful in distinguishing between different types of training in our patient sample. Critically, testing duration was substantially shorter for the entire ACT (10–20 min) than for the AAT (60–90 min). Taken together, the current findings suggest that communicative-pragmatic methods in speech-language testing provide a sensitive and time-effective measure to determine the outcome of aphasia therapy.

Background: Brain damage can impair the use of all languages in bilingual persons. For effective management of aphasia (i.e., impaired language) in such persons, assessment of all languages is essential. The most widely used test for this purpose – the Bilingual Aphasia Test – is cumbersome and requires considerable amount of time for administration. To overcome this limitation, a Short Version of the BAT has been recommended. Objective: The objective of this study was to derive a short version of BAT for Malayalam-English bilingual persons with aphasia and to establish the test-retest reliability as well as the content and construct validities of this version. Materials & Methods: Following the recommendations of the test developers, we used seven subtests from the draft of an adapted full version of Malayalam BAT. These subtests in Malayalam and their counterparts in English were administered on a group of 22 Malayalam-English bilingual participants with aphasia. The scores obtained from these two languages were used to establish content and construct validities of the short version of the BAT in Malayalam. Further, we re-administered the short version of BAT in a group of 10 participants with aphasia to examine the test-retest reliability within 14 days from the date of first administration. Conclusions: The short version of BAT in Malayalam revealed high test-retest reliability as well as content and construct validities. The administration time ranged between 30-45 minutes. Thus, the short version the BAT in Malayalam can be considered a valid and reliable language test that can be quickly administered in Malayalam-English bilingual persons with aphasia.

Background: Discourse is fundamental to everyday communication, and is an increasing focus of clinical assessment, intervention, and research. Aphasia can affect the information a speaker communicates in discourse. Little is known about the psychometrics of the tools for measuring information in discourse, which means it is unclear whether these measures are of sufficient quality to be used as clinical outcome measures or diagnostic tools. Aims: The current review aimed to profile the measures used to describe information in aphasic discourse, and assess the quality of these measures against standard psychometric criteria. Methods: A scoping review method was employed. Studies were identified using a systematic search of Scopus, Medline, and Embase databases. Standard psychometric criteria were used to evaluate the measures’ psychometric properties. Main contribution: The current review summarises and collates the information measures used to describe aphasic discourse, and evaluates their quality in terms of the psychometric properties of acceptability, reliability, and validity. Seventy-six studies described 58 discourse information measures, with a mean of 2.28 measures used per study (SD= 1.29, range 1-7). Measures were classified as functional measures (n= 33), which focused on discourse macrostructure, and functional and structural measures (n= 25), which focused on microlinguistic and macrostructural approaches to discourse as described by Armstrong (2000). There were no reports of the acceptability of data generated by the measures (distribution of scores, missing data). Test-retest reliability was reported for just 8/58 measures with 3/8 > 0.80. Intra-rater reliability was reported for 9/58 measures and in all cases % agreement was reported rather than reliability. Percent agreement was also frequently reported for inter-rater reliability, with only 4/76 studies reporting reliability statistics for 12/58 measures; this was generally high (> .80 for 11/12 measures). The majority of measures related clearly to the discourse production model described by Sherratt (2007), indicating content validity. 36/58 measures were used to make 41 comparisons between PWA and NHP, with 31/41 comparisons showing a difference between the groups. Four comparisons were made between genres, with two measures showing a difference between genres, and two measures showing no difference. Conclusions: There is currently insufficient information available to justify the use of discourse information measures as sole diagnostic or outcome measurement tools. Yet the majority of measures are rooted in relevant theory, and there is emerging evidence regarding their psychometric properties. There is significant scope for further psychometric strengthening of discourse information measurement tools.

Background: Speech-language pathologists (SLPs) measure outcomes to gauge the impact of their interventions and to inform best care for clients. Previous research has explored outcome measurement practices in aphasia rehabilitation, however the factors driving clinician behaviour have not been examined. Aim: To explore current clinical practice and perceived barriers and facilitators to aphasia outcome measurement. Methods and Procedures: Australian SLPs who worked clinically with people with aphasia completed a cross-sectional online survey. Current practice was explored using a combination of multiple-choice questions (with open-text response options) and Likert rating scales. Barriers and facilitators to outcome measurement were explored through ratings of statements aligned with the Theoretical Domains Framework. Data were analysed using descriptive statistics and cross-tabulations. Outcome and Results: Data from 74 Australian SLPs were included. All SLPs reported measuring outcomes and these most frequently related to communication and language. SLPs reported using a diverse range of outcome measures across construct areas and stage-post stroke of service provision, with more than 80 unique instruments/approaches identified. The most frequently used outcome measurement instruments/approaches were: The Western Aphasia Battery – Revised (WAB-R) for language; the Therapy Outcome Measures/Australia Therapy Outcome Measures (TOMs/AusTOMS) for communication, participation, and quality of life; and Goal Attainment Scaling for psychological and carer/significant other outcomes. Overall, SLPs identified more facilitators than barriers to outcome measurement. The main barriers related to the theoretical domains “behavioural regulation” (managing or changing actions) and “memory, attention and decision-making processes” (ability to retain information, focus selectively and choose between alternatives). The main facilitators related to the theoretical domains “beliefs about consequences” (acceptance of the truth, reality, or validity about outcomes of a behaviour) and “social/professional role and identity” (a coherent set of behaviours and displayed personal qualities in a social or work setting). Conclusions: All SLPs reported measuring outcomes with clients with aphasia and these primarily related to language and communication. The outcome measurement instruments/approaches used were heterogeneous within construct areas. SLPs see outcome measurement as part of their role and believe it to be an important activity, however report a need for training and workplace systems and strategies to support optimal practices. The results of this study may inform the development of theoretically informed implementation interventions which seek to improve SLP outcome measurement practice in aphasia rehabilitation.

Purpose: The therapeutic alliance, also known as the therapeutic relationship, may influence treatment process and outcome in aphasia rehabilitation; however, we currently lack a reliable tool to measure this relationship. This study aimed to develop a novel measure of the therapeutic alliance applicable to this population and provide preliminary evidence of the measure’s psychometric properties. Method: Statements were generated from the: (1) therapeutic alliance literature, (2) qualitative interviews with stakeholders, and (3) Q methodological insights with people with aphasia (PWA) (n = 455). A representative sample of statements was identified from the data set (n = 57) and reviewed by expert panels (professionals and PWA), culminating in a 42-item clinician and patient version of the aphasia and stroke therapeutic alliance measure (A-STAM). Reliability and validity of both the clinician and patient versions of A-STAM were investigated with 34 Clinician-patient dyads engaging in therapy. Result: Internal consistency and test–retest reliability were excellent for both clinician (α = 92; ICC = 0.93) and patient versions of A-STAM (α = 0.92; ICC = 0.97). In both versions, scores correlated highly with psychotherapeutic measures of therapeutic alliance, indicative of good construct validity (rs = 0.75; rs = 0.77). Conclusion: The findings establish the preliminary reliability and validity of A-STAM and support further investigation into the measure’s psychometric properties in larger samples.

Background: Stroke is one of the leading causes of disability worldwide and aphasia among survivors is common. Current speech and language therapy (SLT) strategies have only limited effectiveness in improving aphasia. A possible adjunct to SLT for improving SLT outcomes might be non-invasive brain stimulation by transcranial direct current stimulation (tDCS) to modulate cortical excitability and hence to improve aphasia. Objectives: To assess the effects of tDCS for improving aphasia in people who have had a stroke. Search methods: We searched the Cochrane Stroke Group Trials Register (June 2018), CENTRAL (Cochrane Library, June 2018), MEDLINE (1948 to June 2018), Embase (1980 to June 2018), CINAHL (1982 to June 2018), AMED (1985 to June 2018), Science Citation Index (1899 to June 2018), and seven additional databases. We also searched trial registers and reference lists, handsearched conference proceedings and contacted authors and equipment manufacturers. Selection criteria: We included only randomised controlled trials (RCTs) and randomised controlled cross-over trials (from which we only analysed the first period as a parallel group design) comparing tDCS versus control in adults with aphasia due to stroke. Data collection and analysis: Two review authors independently assessed trial quality and risk of bias, and extracted data. If necessary, we contacted study authors for additional information. We collected information on dropouts and adverse events from the trials. Main results: We included 21 trials involving 421 participants in the qualitative synthesis. Three studies with 112 participants used formal outcome measures for our primary outcome measure of functional communication - that is, measuring aphasia in a real-life communicative setting. There was no evidence of an effect (standardised mean difference (SMD) 0.17, 95% confidence interval (CI) -0.20 to 0.55; P = 0.37; I² = 0%; low quality of evidence; inverse variance method with random-effects model; higher SMD reflecting benefit from tDCS; moderate quality of evidence). At follow-up, there also was no evidence of an effect (SMD 0.14, 95% CI -0.31 to 0.58; P = 0.55; 80 participants ; 2 studies; I² = 0%; very low quality of evidence; higher SMD reflecting benefit from tDCS; moderate quality of evidence).For our secondary outcome measure, accuracy in naming nouns at the end of intervention, there was evidence of an effect (SMD 0.42, 95% CI 0.19 to 0.66; P = 0.0005; I² = 0%; 298 participants; 11 studies; inverse variance method with random-effects model; higher SMD reflecting benefit from tDCS; moderate quality of evidence). There was an effect for the accuracy in naming nouns at follow-up (SMD 0.87, 95% CI 0.25 to 1.48; P = 0.006; 80 participants; 2 studies; I² = 32%; low quality of evidence); however the results were not statistically significant in our sensitivity analysis regarding the assumptions of the underlying correlation coefficient for imputing missing standard deviations of change scores. There was no evidence of an effect regarding accuracy in naming verbs post intervention (SMD 0.19, 95% CI -0.68 to 1.06; P = 0.67; I² = 0%; 21 participants; 3 studies; very low quality of evidence). We found no studies examining the effect of tDCS on cognition in people with aphasia after stroke. We did not find reported serious adverse events and the proportion of dropouts and adverse events was comparable between groups (odds ratio (OR) 0.54, 95% CI 0.21 to 1.37; P = 0.19; I² = 0%; Mantel-Haenszel method with random-effects model; 345 participants; 15 studies; low quality of evidence). Authors' conclusions: Currently there is no evidence of the effectiveness of tDCS (anodal tDCS, cathodal tDCS and Dual-tDCS) versus control (sham tDCS) for improving functional communication in people with aphasia after stroke (low quality of evidence). However, there is limited evidence that tDCS may improve naming performance in naming nouns (moderate quality of evidence), but not verbs (very low quality of evidence) at the end of the intervention period and possibly also at follow-up. Further methodologically rigorous RCTs with adequate sample size calculation are needed in this area to determine the effectiveness of this intervention. Data on functional communication and on adverse events should routinely be collected and presented in further publications as well as data at follow-up. Further study on the relationship between language/aphasia and cognition may be required, and improved cognitive assessments for patients with aphasia developed, prior to the use of tDCS to directly target cognition in aphasia. Authors should state total values at post-intervention as well as their corresponding change scores with standard deviations.
Article
More than 50 years of research has demonstrated the profound effect that aphasia has on people with the condition and their family members. In the International Classification of Functioning, Disability and Health, the World Health Organization described the impact of an individual's health condition on a significant other as "third-party disability." Recent research has described how third-party disability can occur in family members of people with aphasia post-stroke. Despite the extensive history and ongoing relevance of these findings, family-centered rehabilitation has been slow to integrate into clinical practice and policy. The aims of this article are (1) to provide an overview of third-party disability in family members of people with aphasia; (2) to consider how third-party disability can be addressed through family-centered care and to identify some of the barriers to family-centered care; and (3) to describe The Family Aphasia Measure of Life Impact (FAMLI), a tool for measuring third-party functioning and disability in family members of people with aphasia, identifying family rehabilitation needs, and measuring outcomes of family-centered care.

Background: The psychometric properties of the Dutch version of the Stroke and Aphasia Quality Of Life-scale (SAQOL-39NL) have previously been assessed for people with aphasia after stroke, but not yet for stroke survivors without aphasia. Objective: The objective is to evaluate the psychometric properties of the SAQOL-39NL in a stroke sample with and without aphasia. Methods: The SAQOL-39NL was administered to survivors of stroke (N = 141) who received rehabilitation in specialized rehabilitation facilities, 3 and 6 months after the start of rehabilitation. Acceptability was explored by assessing floor and ceiling effects and missing items. For internal consistency, Cronbach’s alpha and item-total correlations were computed. For internal validity, intercorrelations between domains, and between domains and total score, were assessed. Convergent validity was evaluated by correlation with EuroQoL-5D scores. Responsiveness to change was investigated using d′ and SRM-scores. Results: Mean age was 60.4 years (SD = 11.1), 62.4% were male. Mean total SAQOL-39NLg score was 3.94 (SD = 0.68, scale 1–5). No floor or ceiling effects and 2.4% missing data were found. Internal consistency was excellent (Cronbach’s alpha = 0.96). Intercorrelations between domains and total scale were moderate to excellent (r = 0.57–0.88). Intercorrelations between domains were low to moderate (r = 0.22–0.63). The correlation with the EQ-5D was moderate (r = 0.57). Only small changes in SAQOL-39NLg scores were found between 3 and 6 months. Conclusions: These data provide further evidence for the acceptability, internal consistency, and initial promising data on validity of the SAQOL-39NLg. Further research on structural validity and responsiveness to change is needed.

Background: A core outcome set (COS; an agreed, minimum set of outcomes) was needed to address the heterogeneous measurement of outcomes in aphasia treatment research and to facilitate the production of transparent, meaningful, and efficient outcome data. Objective: The Research Outcome Measurement in Aphasia (ROMA) consensus statement provides evidence-based recommendations for the measurement of outcomes for adults with post-stroke aphasia within phases I-IV aphasia treatment studies. Methods: This statement was informed by a four-year program of research, which comprised investigation of stakeholder-important outcomes using consensus processes, a scoping review of aphasia outcome measurement instruments, and an international consensus meeting. This paper provides an overview of this process and presents the results and recommendations arising from the international consensus meeting. Results: Five essential outcome constructs were identified: Language, communication, patient-reported satisfaction with treatment and impact of treatment, emotional wellbeing, and quality of life. Consensus was reached for the following measurement instruments: Language: The Western Aphasia Battery Revised (WAB-R) (74% consensus); emotional wellbeing: General Health Questionnaire (GHQ)-12 (83% consensus); quality of life: Stroke and Aphasia Quality of Life Scale (SAQOL-39) (96% consensus). Consensus was unable to be reached for measures of communication (where multiple measures exist) or patient-reported satisfaction with treatment or impact of treatment (where no measures exist). Discussion: Harmonization of the ROMA COS with other core outcome initiatives in stroke rehabilitation is discussed. Ongoing research and consensus processes are outlined. Conclusion: The WAB-R, GHQ-12, and SAQOL-39 are recommended to be routinely included within phases I-IV aphasia treatment studies. This consensus statement has been endorsed by the Collaboration of Aphasia Trialists, the British Aphasiology Society, the German Society for Aphasia Research and Therapy, and the Royal College of Speech Language Therapists.

Objective: To evaluate an observational-behavioral pain tool among individuals with acute poststroke aphasia. Methods: We performed a randomized, double-blind, controlled study of experimental pain assessment among 36 adult patients with acute poststroke aphasia. Patients were administered 3 levels of mechanical pain, including placebo. The behavioral responses were video recorded and then evaluated by 3 neurology nurses using the Pain Assessment Checklist for Seniors With Limited Ability to Communicate (PACSLAC-II). Pain-specific facial action units were quantified with FaceReader version 6.1. Results: Median PACSLAC-II ratings for 0-, 2-, and 4.5-lb weight stimuli were 2 (0, 3), 1 (0, 3), and 2 (1, 5), respectively. Overall, differences were not detected (p = 0.06). Pairwise comparisons with the Wilcoxon method demonstrated significance in differentiating PACSLAC-II ratings of patients experiencing the 4.5-lb stimulus vs either the 2-lb weight (p = 0.03) or placebo (p = 0.05). Overall interrater reliability by the Cronbach α was strong at 0.87, 0.94, and 0.96 for weights of 0, 2, and 4.5 lb, respectively. Pain-specific facial activation and negative valence were observed similarly in placebo and experimental pain groups. Conclusions: Among our cohort with acute poststroke aphasia, the PACSLAC-II was not able to overall differentiate patients experiencing experimental mechanical pain, although differences in those experiencing the strongest pain stimulus were significant. The detection of pain-specific facial activation and negative valence in the placebo group indicates that pain and distress are unmet needs among stroke patients who are unable to verbally communicate.

Aim: To develop a time-efficient Arabic test battery for adult-onset chronic aphasia that provides information about the type and the severity of the disorder. Patient and methods: A total of 90 participants were recruited and divided into 3 groups. The groups consisted of 30 adult-onset post-stroke chronic aphasic patients, 30 adult non-aphasic adults with central neurological disorders, and a group of 30 non-brain-damaged healthy adults. All participants were assessed using the Mansoura Arabic Screening Aphasia Test (MASAT), which consists of 4 main sections: (1) language expression abilities including repetition and naming items, (2) language comprehension questions, (3) fluency, and (4) reading, writing and calculation items. The content validity, internal consistency, clinical validity, and convergent validity of the MASAT were evaluated. Results: The MASAT demonstrated statistically high reliability and validity. The high α-values in all subtotal scores among the 3 groups were judged to denote excellent intercorrelation among the screening test items. Conclusion: The MASAT is a valid and a reliable brief assessment tool that can be completed on the first clinic appointment that detects the type and severity of Arabic-speaking aphasic patients.

Purpose: To study the relationship between the caregiver’s perception about the patient’s impairment in spontaneous speech, according to an item of four questions administered by semi-structured interview, and the patient’s performance in the Brief Aphasia Evaluation (BAE). Methods: 102 right-handed patients with focal brain lesions of different types and location were examined. BAE is a valid and reliable instrument to assess aphasia. The caregiver’s perception was correlated with the item of spontaneous speech, the total score and the three main factors of the BAE: Expression, Comprehension and Complementary factors. The precision (sensitivity/ specificity) about the caregiver’s perception of the patient’s spontaneous speech was analyzed with reference to the presence or absence of disorder, according to the professional, on the BAE item of spontaneous speech. Results: The studied correlation was satisfactory, being greater (higher than 80%) for the following indicators: the item of spontaneous speech, the Expression factor and the total score of the scale; the correlation was a little smaller (higher than 70%) for the Comprehension and Complementary factors. Comparing two cut-off points that evaluated the precision of the caregiver’s perception, satisfactory results were observed in terms of sensitivity and specificity (>70%) with likelihood ratios higher than three. By using the median as the cut-off point, more satisfactory diagnostic discriminations were obtained. Conclusion: Interviewing the caregiver specifically on the patient’s spontaneous speech, in an abbreviated form, provides relevant information for the aphasia diagnosis.

Purpose: To evaluate the psychometric properties of the Italian version of Functional Outcome Questionnaire – Aphasia. Methods: Two hundred and five persons with stroke-related aphasia and right hemiparesis who received ongoing assistance from a family caregiver were assessed using the Functional Outcome Questionnaire – Aphasia, Aachener Aphasie Test, Token Test, Raven’s Coloured Progressive Matrices, Functional Independence Measure (FIM), Functional Assessment Measure (FAM), and Quality of Life Questionnaire for Aphasics (QLQA). The Functional Outcome Questionnaire – Aphasia was translated into the Italian language using a translation and back-translation method. Reliability and construct validity of the Functional Outcome Questionnaire – Aphasia were evaluated. Results: The Italian version of the Functional Outcome Questionnaire – Aphasia showed good internal consistency and test–retest reliability for the overall scale (α = 0.98; ICC = 0.95) and subscales (α = 0.89 for the communicating basic needs (CBN), α = 0.92 for the making routine requests (MRR), α = 0.96 for the communicating new information (CNI), α = 0.93 for the attention/other communication skills (AO); ICC = 0.95 for CBN, ICC = 0.96 for MRR, ICC = 0.97 for CNI and ICC = 0.92 for AO). Significant correlations were found between the Functional Outcome Questionnaire – Aphasia and Token Test, QLQA, Aachener Aphasie Test scores, and FAM linguistic scores, indicating good convergent validity. Low correlations were found between Functional Outcome Questionnaire – Aphasia and Raven’s Coloured Progressive Matrices and FIM motor scores, showing good discriminant validity. Conclusions: The overall findings of this study supported the reliability and construct validity of the Italian version of the Functional Outcome Questionnaire – Aphasia. This measure holds considerable promise in assessing the functional outcomes of aphasia rehabilitation in Italian-speaking persons with aphasia. • Implications for Rehabilitation • Functional Outcome Questionnaire – Aphasia is a reliable and valid questionnaire in assessing functional communication of Italian-speaking people with aphasia. • This measure provides critical information about people with aphasia’s functional and pragmatic communication in home and community settings, contributing significantly to overall quality of life. • Since the use of measures of functional communication is recommended in the clinical evaluation of language disease, the Italian version of Functional Outcome Questionnaire – Aphasia may be effective in tailoring rehabilitation treatment to the presenting communication problems of people with aphasia and their caregivers.

The Birmingham Cognitive Screen (BCoS) is a neuropsychological battery designed to assess impairment to a variety of cognitive domains including language in patients with brain injuries. Twenty-two stroke participants and 16 gender-, age-, and education-matched controls were recruited in Hong Kong. The stroke participants were administered HK-BCoS as well as standardized batteries of cognitive and language functions validated for the Cantonese-speaking population in Hong Kong, including the Cantonese version of the Western Aphasia Battery, Cantonese Mini-Mental State Examination, and the Hong Kong–Montreal Cognitive Assessment. Results showed that HK-BCoS demonstrated good concurrent validity with all standardized batteries. HK-BCoS could discriminate between cognitive impairments in stroke patients and normal participants. Furthermore, HK-BCoS was found to have excellent intrarater and interrater reliabilities, good test–retest reliability, and fair split-half reliability as judged according to international criteria. In sum, HK-BCoS is a valid and reliable tool for assessing cognitive processing in Cantonese speakers in Hong Kong.

Finding, testing and demonstrating efficacy of new treatments for stroke recovery is a multifaceted challenge. We believe that to advance the field, neurorehabilitation trials need a conceptually rigorous starting framework. An essential first step is to agree on definitions of sensorimotor recovery and on measures consistent with these definitions. Such standardization would allow pooling of participant data across studies and institutions aiding meta-analyses of completed trials, more detailed exploration of recovery profiles of our patients and the generation of new hypotheses. Here, we present the results of a consensus meeting about measurement standards and patient characteristics that we suggest should be collected in all future stroke recovery trials. Recommendations are made considering time post stroke and are aligned with the international classification of functioning and disability. A strong case is made for addition of kinematic and kinetic movement quantification. Further work is being undertaken by our group to form consensus on clinical predictors and pre-stroke clinical data that should be collected, as well as recommendations for additional outcome measurement tools. To improve stroke recovery trials, we urge the research community to consider adopting our recommendations in their trial design.

Objective: 1) To develop a systems level quality improvement tool targeting communicative access to information and decision-making for stroke patients with language disorders and 2) to evaluate the resulting tool - Communicative Access Measures for Stroke (CAMS). Design: Survey development and evaluation was in line with accepted guidelines, and included item generation and reduction, survey formatting and composition, pre-testing, pilot-testing, and reliability assessment. Setting: Development and evaluation were carried out in hospital and community agency settings. Participants: The project utilized a convenience sample of 31 participants for the survey development, and 63 participants for the CAMS reliability study (broken down into 6 administrators/managers, 32 frontline staff, 25 participants with aphasia). The number of eligible participants invited to the reliability study included 45 community-based organizations in Ontario as well as 4400 individuals from communities of practice. Interventions: Not applicable. Main outcome measure(s): Data were analyzed using kappa statistics and intraclass correlations for each item score on all surveys. Results: A tool, the Communicative Access Measures for Stroke (CAMS), comprising three surveys, was developed for health facilities from the perspectives of 1) administrators/policy makers, 2) staff/frontline health care providers, and 3) patients with aphasia (using a communicatively accessible version). Reliability for items on the CAMS Administrator and CAMS Staff surveys was moderate to high (Kappa/ICCs ranging from 0.54 to 1.00). As expected, reliability was lower for the CAMS Patient survey with most items having ICCs between 0.4 and 0.6. Conclusion: (s): These findings suggest that CAMS may provide useful quality improvement information for health care facilities with an interest in improving care for patients with stroke and aphasia.

The need for quick tools to sketch an early but accurate cognitive profile of patients who suffered brain damage or head trauma is of primary importance. Nonetheless, in the Italian context, the most-diffused screening tools are still those originally devised to diagnose dementia. The present pilot study then aimed at investigating the potential and feasibility of a novel screening battery, the Cognitive Assessment for Stroke Patients (CASP), in a sample of Italian patients by comparing it to Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) tests. A total of 29 neurology patients took part in the study. Participants underwent a screening procedure including the administration of MMSE, MoCA, and CASP. Data analysis suggested that the scores of the Italian version of the CASP are relatively less affected by the presence of language difficulties—common sequelae of stroke and head traumas—with respect to MMSE and MoCA ones. Furthermore, CASP scores proved to be highly correlated with both MMSE and MoCA scores, showing good clinical potential. Finally, the outcomes of administered tests proved not to be influenced by etiology or gender, and CASP scores showed a diminishing trend related to patients’ age and a positive association with patients’ education.

Purpose: Stepped psychological care is the delivery of routine assessment and interventions for psychological problems, including depression. The aim of this systematic review was to analyze and synthesize the evidence of rehabilitation interventions to prevent and treat depression in post-stroke aphasia and adapt the best evidence within a stepped psychological care framework. Method: Four databases were systematically searched up to March 2017: Medline, CINAHL, PsycINFO and The Cochrane Library. Results: Forty-five studies met inclusion and exclusion criteria. Level of evidence, methodological quality and results were assessed. People with aphasia with mild depression may benefit from psychosocial-type treatments (based on 3 level ii studies with small to medium effect sizes). For those without depression, mood may be enhanced through participation in a range of interventions (based on 4 level ii studies; 1 level iii-3 study and 6 level iv studies). It is not clear which interventions may prevent depression in post-stroke aphasia. No evidence was found for the treatment of moderate to severe depression in post-stroke aphasia. Conclusions: This study found some interventions that may improve depression outcomes for those with mild depression or without depression in post-stroke aphasia. Future research is needed to address methodological limitations and evaluate and support the translation of stepped psychological care across the continuum. • Implications for Rehabilitation • Stepped psychological care after stroke is a framework with levels 1 to 4 which can be used to prevent and treat depression for people with aphasia. • A range of rehabilitation interventions may be beneficial to mood at level 1 for people without clinically significant depression (e.g., goal setting and achievement, psychosocial support, communication partner training and narrative therapy). • People with mild symptoms of depression may benefit from interventions at level 2 (e.g., behavioral therapy, psychosocial support and problem solving). • People with moderate to severe symptoms of depression require specialist mental health/behavioral services in collaboration with stroke care at levels 3 and 4 of stepped psychological care.

Introduction: The Birmingham Cognitive Screen (BCoS) is designed for use with individuals who have acquired language impairment following stroke. Our goal was to develop a Russian version of the BCoS (Rus-BCoS) by translating the battery following cultural and linguistic adaptations and establishing preliminary data on its psychometric properties. Method: Fifty patients with left-hemisphere stroke were recruited, of whom 98% were diagnosed with mild to moderate aphasia. To check whether the Rus-BCoS provides stable and consistent scores, internal consistency, test– retest, and interrater types of reliability were determined. Eight participants with stroke and 20 neurologically intact participants were assessed twice. To inspect the discriminative power of the battery, 63 participants without brain impairment were tested with the Rus-BCoS. Additionally, the Russian version of the Montreal Cognitive Assessment (MoCA), Quantitative Assessment of Speech in Aphasia, and Luria's Neuropsychological Assessment Battery were used to examine convergent validity, sensitivity, and specificity of the Rus-BCoS. Results: The internal consistency as well as test–retest and interrater reliability of the Rus-BCoS satisfied criteria for the research use. Performance on a majority of tasks in the battery correlated significantly with independently validated tests that putatively measure similar cognitive processes. Critically, all patients with aphasia returned nonzero scores in at least one task in all the Rus-BCoS sections, with the exception of the Controlled Attention section where two patients with severe executive control deficits could not perform. Conclusions: The Rus-BCoS shows promise as a comprehensive cognitive screening tool that can be used by clinicians working with Russian-speaking persons experiencing poststroke aphasia after much further validation and development of reliable normative standards. Given a lack of quantitative neuropsychological assessment tools in Russia, however, we contend the Rus-BCoS offers potential benefits to clinicians and patients. However, data from research studies with a broader sample of Russian speakers are needed.

Purpose: We developed and explored the feasibility and user acceptance of the Cognitive Assessment for Aphasia App: a non-immersive virtual reality cognitive assessment for stroke survivors, designed to be inclusive of individuals with aphasia. Methods: Participants were assessed on a battery of pen-and-paper cognitive tests and the Cognitive Assessment for Aphasia App. Feasibility was explored by quantifying missing data for test completion, determining user acceptance for the app by measuring participants’ preferred testing method, enjoyment and perceived task difficulty and time-taken to complete the test. Results: Sixty-four stroke participants (35 with aphasia, 29 without aphasia) and 32 controls were recruited. Only one participant with aphasia was unable to complete all the Cognitive Assessment for Aphasia App tasks, whereas 13 participants were unable to complete all pen-and-paper tasks. Only 14% of participants preferred the pen-and-paper tests, and preference did not significantly differ between groups. Ninety-five per cent of participants were neutral or enjoyed the app and 4% perceived it to be very difficult. Higher age was negatively associated with user acceptance measures. Conclusion: The study shows preliminary evidence for the Cognitive Assessment for Aphasia App to be a feasible cognitive assessment for stroke survivors with and without aphasia. The app is currently being validated in stroke.

Purpose: Evaluation of the Naming and Oral Reading for Language in Aphasia 6-point scale (NORLA-6), a scoring system of oral reading and naming performance in aphasia. Method: Data were drawn from 91 participants with non-fluent aphasia secondary to left-hemisphere stroke across four treatment studies. To assess validity, Spearman's correlations were calculated between the NORLA-6 and the Gray Oral Reading Test-Fourth Edition (GORT-4) Accuracy score, GORT-4 Rate score and the Boston Naming Test (BNT). Inter-rater and test-retest reliability were evaluated using correlations. Sensitivity to change following oral reading intervention was analysed using Wilcoxon Signed Rank tests between pre- and post-treatment NORLA-6 scores. Result: NORLA-6 performance was significantly correlated (p < 0.001) with all reference tests (GORT-4 Accuracy, rs=0.84; GORT-4 Rate, rs= 0.61; and BNT, rs= 0.92). Inter-rater (ICC ≥0.90) and test-retest (r > 0.92) reliability were both excellent. Sensitivity following oral reading intervention was demonstrated in both oral reading accuracy and rate (p < 0.004). Conclusion: The NORLA-6 is a valid and reliable measure of oral reading and naming performance. It also demonstrates sensitivity to change in treatment-targeted behaviours. Therefore, the NORLA-6 scale may enhance outcome measurement in both clinical practice and aphasia research.

Purpose: The purpose of this article is to identify outcome constructs that aphasia researchers consider essential to measure in all aphasia treatment research. Method: Purposively sampled researchers were invited to participate in a 3-round e-Delphi exercise. In Round 1, an open-ended question was used to elicit important outcome constructs; responses were analyzed using inductive content analysis. In Rounds 2 and 3, participants rated the importance of each outcome using a 9-point rating scale. Outcomes reaching predefined consensus criteria were further analyzed using International Classification of Functioning, Disability and Health coding. Results: Eighty researchers commenced Round 1, with 72 completing the entire survey. High response rates (≥ 85%) were achieved in subsequent rounds. Consensus was reached on 6 outcomes: (a) language functioning in modalities relevant to study aims, (b) impact of treatment from the perspective of the person with aphasia (PWA), (c) communication-related quality of life, (d) satisfaction with intervention from the perspective of the PWA, (e) satisfaction with ability to communicate from the perspective of the PWA, and (f) satisfaction with participation in activities from the perspective of the PWA. Conclusions: Consensus was reached that it is essential to measure language function and specific patient-reported outcomes in all aphasia treatment research. These results will contribute to the development of a core outcome set.
