Background Given the recent evidence on gender differences in the presentation of autism, there is an increasing concern that current tools for autism do not adequately capture traits more often found in women. If tools for autism measure autistic traits differently based on gender alone, their validity may be compromised as they may not be measuri...

Across research studies, autistic traits have consistently been found to predict the quality of life (QoL) of autistic adults. However, our understanding of their exact role remains limited, as autistic traits are typically examined as a unitary construct, with their multidimensional nature being largely overlooked. The present study examined the r...

Some autistic adults experience repeated adverse events, including rejection, victimization and stigmatization. They also describe others being critical and negatively judging them, such as for how they socially interact or for expressing passion for particular interests. The impact of these adverse events can be substantial, including increasing v...

It was recently reported that learning one is autistic earlier in life is associated with greater quality of life and well-being in university students. In a pre-registered extension of this work, we addressed several limitations of this study by (a) recruiting a larger sample of more diverse ages and education levels, (b) distinguishing between le...

Autistic people often have an atypical profile of abilities: while excelling in some structured paradigms, many report difficulties with making real-life decisions. To test whether decision-making in autism is different from in typically developing controls, we reviewed 104 studies that compared decision-making performance between autistic and comp...

Autistic people often have an atypical profile of abilities: while excelling on some structured paradigms, many report difficulties with making real life decisions.

Autistic people experience more health conditions and earlier mortality. This study investigated views about a primary care health check for autistic adults to inform its design. Fifty-one people participated in consultation groups and interviews, comprising autistic adults (some with co-occurring intellectual disabilities), adults with intellectua...

Background: While many studies have examined where and with whom autistic people live, very few have looked at autistic people's experience of moving home. Choosing where to live, and being able to move residence, could be important for autonomy, and we therefore undertook a systematic review to identify studies about autistic adults' experience o...

Background: In the United Kingdom, we have experienced many changes to our daily lives as a result of COVID-19. Autistic and other neurodivergent (ND, e.g., those with attention-deficit hyperactivity disorder) adults may be more vulnerable to negative effects of the pandemic due to pre-existing mental health disparities and unmet support needs. Fu...

Background: Compared to the general population, autistic adults experience higher rates of physical and mental health conditions, premature morbidity and mortality, and barriers to healthcare. A health check for autistic people may improve their health outcomes. Aim: To establish the views of autistic people toward a primary care health check fo...

Background Access to timely high quality autism diagnostic assessments has traditionally been patchy; many individuals wait months, if not years, for an appointment. The onset of the COVID-19 pandemic has likely impacted autism diagnostic services. This study investigated professionals' experiences of, and thoughts about: (1) how autism diagnostic...

There is emerging evidence of the effectiveness of individual and group cognitive behaviour therapy (CBT) for autistic individuals, in particular to address anxiety, obsessive compulsive disorder and depression. Many CBT studies have incorporated relatively stringent standards, with regards to participant inclusion/exclusion criteria, delivery of m...

BACKGROUND Autism spectrum disorder (hereafter, autism) is a common neurodevelopmental condition. Core traits can range from subtle to severe, and fluctuate depending on context. Individuals can present for a diagnostic assessment in childhood or adulthood. However, waiting times for assessment are typically lengthy; many individuals wait months, o...

Background: Autism spectrum disorder (hereafter, autism) is a common neurodevelopmental condition. Core traits can range from subtle to severe and fluctuate depending on context. Individuals can present for diagnostic assessments during childhood or adulthood. However, waiting times for assessment are typically lengthy, and many individuals wait m...

There is increasing empirical evidence to suggest that psychological therapies can be effective for targeting mental health symptoms experienced by autistic adults. However, relatively little is known about what autistic adults think about the structure and content of psychological therapies and which elements of the therapeutic process are more or...

Background: Measurement of the Quality of Life (QoL) of autistic adults is receiving increasing empirical attention. The World Health Organisation (WHO) QoL measure (WHOQoL-BREF) has been utilised in several studies. Autistic adults report significantly lower QoL compared to neurotypical adults across several domains. However, no studies have inves...

Background Autistic people tend to report poorer Quality of Life (QOL) than comparison groups, though some studies do report more optimistic findings. Higher autistic traits are also related to poorer QOL. However, the role of alexithymia in this relationship has not been explored. Method A total of 163 participants (N = 53 autistic and N = 111 co...

Background: There is a paucity of research involving older autistic people, as highlighted in a number of systematic reviews. However, it is less clear whether this is changing, and what the trends might be in research on autism in later life. Methods: We conducted a broad review of the literature by examining the number of results from a search i...

Longitudinal studies have generally reported poor outcomes in adulthood for the majority of individuals (c.50–60%) with autism. Several factors putatively predict outcome (e.g. IQ), but findings remain mixed. This paper presents an updated meta-analysis of autism outcome studies and extends previous findings with additional analyses (including meta...

Do people have privileged and direct access to their own minds, or do we infer our own thoughts and feelings indirectly, as we would infer the mental states of others? In this study we shed light on this question by examining how mentalizing ability—the set of processes involved in understanding other people’s thoughts and feelings—relates to metac...

Growing evidence indicates that the defining characteristics of autism spectrum disorder (ASD) are distributed throughout the general population; hence, understanding the correlates of aging in people with high autistic traits could shed light on ASD and aging. 915 members of the Dunedin longitudinal birth cohort completed a measure of autistic tra...

Background The COVID-19 (C-19) pandemic affects everyone. Autistic individuals may be at increased risk of experiencing difficulties coping with the impact of C-19 (e.g. due to unexpected changes to usual activities and routines, and the general sense of uncertainty). This preliminary study gathered the perspectives of health and social care profes...

Autism spectrum condition is associated with co-occurring physical health conditions and premature mortality. Autistic people experience multiple barriers to accessing healthcare. This study investigated autistic people’s experiences of healthcare and professionals’ experiences of providing healthcare to autistic people. Focus groups with 11 autist...

Objectives To investigate autistic people’s views on the importance and availability of adjustments to mental and physical healthcare provision. To explore whether specific categories of adjustments can be identified and to identify any differences in their importance and availability between mental and physical healthcare. Design Data from two st...

Objective Mortality from thyroid cancer is reported to be higher in the UK compared to several other European countries, though UK data on mortality by disease stage have not been published. The aim of this study was to ascertain disease‐specific mortality by stage in our centre. Design, Patients And Measurements This was a cohort study of all pat...

Background: Anxiety is highly prevalent in autistic adults and can cause a significant impact on functioning and quality of life. There are no existing measures of anxiety designed and validated specifically for autistic adults. In this study, we aimed to adapt an existing anxiety measure designed for autistic children, in collaboration with autist...

Unlabelled: Relevant and valid measurement is crucial in determining whether interventions and supports have improved the quality of life (QoL) of autistic people. However, it is possible that researchers' and services' use of general population QoL tools may overlook issues of specific importance. To advance methodology, we conducted a preliminar...

Autistic people are more likely to: be diagnosed with a range of physical health conditions (i.e. cardio-vascular disease); experience premature mortality (for most disease categories); and experience barriers to effectively accessing healthcare. This systematic review sought to identify studies that report on barriers and facilitators to physical...

Background: Having a mental health condition is related to significantly lower subjective Quality of Life (QoL) for people on the autism spectrum. Many autistic people do not participate in so-called ‘normative’ outcomes, i.e. the achievement of lifecourse goals judged to be important by adults in the general population (e.g. being employed). This...

Research with adults on the autism spectrum is as yet limited in scope and quality. The present study describes quality of life (QoL) of a large sample of autistic adults in the UK and investigates characteristics that may be predictive of QoL. A total of 370 autistic adults from the Adult Autism Spectrum Cohort‐UK (ASC‐UK) completed the WHOQoL‐BRE...

Accurate measurement of quality of life (QoL) is important for evaluation of autism services and trials of interventions. We undertook psychometric validation of the World Health Organisation measure—WHOQoL-BREF, examined construct validity of the WHO Disabilities module and developed nine additional autism-specific items (ASQoL) from extensive con...

Autism spectrum disorder is associated with co-existing conditions that may adversely affect an individual’s quality of life. No systematic review of quality of life of adults on the autism spectrum has been conducted. Our objectives were as follows: (1) review the evidence about quality of life for adults on the autism spectrum; (2) critically app...
