Situational Crisis Communication Theory (SCCT) guides responses of corporations in crises. We tested how COVID-19 related crisis communication strategies affect trust in mayors and the acceptance of behavioral measures. A total of 561 participants (53% female) with a mean age of 50 years took part in an online experiment in which we systematically...
Preprint
Introduction: The communication patterns of commercial organizations are generally guided by Situational Crisis Communication Theory (SCCT), but the impact of different crisis communication strategies for public messaging on COVID-19 has not been thoroughly examined. As such, we test how crisis communication strategies affect trust in mayors and th...

In digital media and on the World Wide Web, content is king. As such, users’ subjective perceptions of content can influence a variety of their evaluations, thereby altering their attitudes and behavioral outcomes. Thus, users’ content perceptions need to be assessed using a valid measure, but this often has to be done while keeping the survey time...

Background Parental reactions to their child’s pain can comprise cognitive-affective and behavioral responses. Dysfunctional responses like parental catastrophizing may lead to an aggravation of the child’s pain. Objectives Aims of the online-based study were (1) to psychometrically evaluate existing questionnaires into cognitive-affective (Pain C...

Content is of primary importance in the World Wide Web. In particular, subjective perceptions of content are known to influence a variety of user evaluations, thereby altering attitudes and behavioral outcomes. Thus, it is essential that individually experienced facets of content can be adequately assessed. In a series of seven studies, we create,...

Mental rotation tasks with objects and body-parts as targets are widely used in cognitive neuropsychology. Even though these tasks are well established to study between-group differences, the reliability on an individual level is largely unknown. We present a systematic study into the internal consistency and test-retest reliability of individual d...

Objective: Many diagnostic studies are aimed at defining “optimal” thresholds. Here, we evaluate the performance of empirically defined “optimal” thresholds (a) in the sample in which they were defined, and (b) in the population from which the sample was drawn. Study design: We simulated test results for 120,000 samples varying the number of people...

Objective: To investigate the long-term effectiveness of a 3-week multimodal inpatient program for children and adolescents with chronic pain. Methods: 167 adolescents were evaluated at pretreatment baseline, 3-, and 12-month follow-up. Long-term effectiveness was investigated for pain-related variables (pain-related disability, school absence,...

... First, we have not investigated possible differences between subgroups of users and/or websites. We have recently shown that expert designers apply more stringent criteria when ratings the aesthetics of websites (Hirschfeld, Wachlin, and Thielsch 2013). While more research is necessary to investigate such differences in more detail this findings also highlights the need for tools that can be used by design experts to gather and interpret ratings of non-experts. ...
... The short version of the Web-CLIC, which measures subjective web content perception, was used to assess the divergent validity (Thielsch & Hirschfeld, 2021). The scale consists of four items, and it is scored on a Likert-type scale that ranges from 1 (totally disagree) to 7 (totally agree). ...
... Disagreements between these 2 raters (10.2%) were resolved by an expert (J.W.). This procedure led to the addition of 35 articles 6,10,11,19,21,24,27,29,39,40,44,52,55,65,[67][68][69]73,81,90,92,99,101,102,104,106,109,112,113,115,119,120,122,141,144 to the 16 previously identified articles to the description of published treatments. In sum, 51 individual articles were included in the description of treatment programs. ...

... In many cases, questionnaires are used to measure the user experience of products or services because UX questionnaires are easy to use, and a common quantitative way to measure user experience [2]. There are various UX questionnaires, such as meCUE [3], SUPR-Q [4], UEQ [5], [6], VisAWI [7], and Web-CLIC [8]. One goal of using a UX questionnaire is the idea of getting a better understanding of the own product or service and making appropriate improvements. ...
... Accordingly, larger changes in pain scores with increasing baseline pain intensities were documented in the studies by Patterson and Berger. The large variability in the absolute minimal clinically relevant difference from 1 to 4 on a 0-10 NRS has been found in studies investigating pain relief in acute, cancer-related and persistent pain (Hirschfeld, Wager, Schmidt, & Zernikow, 2014;Hui et al., 2015;M. F. Olsen et al., 2017). ...
... We know of only four studies that have investigated the degree to which data-driven selection of cutoff may influence diagnostic accuracy estimates [15][16][17][18] . These studies each reported that data-driven cutoff selection produces overly optimistic estimates, particularly in small samples. ...
... Our findings regarding the influence of participant characteristics on performance are similar to previously reported data which supports validity of our results. Absence of a speed-accuracy tradeoff has been reported in several previous studies (Saimpont et al., 2009; Richter et al., 2010; Hirschfeld et al., 2013), and also in line with previous reports we noted significantly faster RT regarding the right foot compared to the left (Fiorio et al., 2007; Coslett et al., 2010a,b). In our sample older age was related to both decreased ACC as well as slower RT for trunk laterality judgments . ...
... 15 Despite multidisciplinary pain treatment approaches, only 40%-60% of adolescents with chronic MSK pain achieve and sustain improvements in relevant clinical endpoints including pain and functional disability. [16][17][18][19][20][21] Discovery of robust prognostic markers differentiating patients who recover from patients with persistent pain and disability is essential to develop more resource efficient and patient-specific treatment strategies and to conceive novel treatment approaches that benefit patients whose pain and disability are refractory to current options. Such discovery is particularly pressing for the paediatric population, as the management of paediatric chronic pain is often absent from policy and funding ...
