RESUMO
BACKGROUND: Semi-automated software is essential for planning and prosthesis selection prior transcatheter aortic valve replacement (TAVR). Reliable data on the usability of software programs for planning a TAVR is missing. The aim of this study was to compare software programs 'Valve Assist 2' (GE Healthcare) and 3mensio 'Structural Heart' (Pie Medical Imaging) regarding usability and accuracy of prosthesis size selection in program-inexperienced users. METHODS: Thirty-one participants (n = 31) were recruited and divided into program-inexperienced users (beginners) (n = 22) and experts (n = 9). After software training, beginners evaluated 3 patient cases in 129 measurements (n = 129) using either Valve Assist 2 (n = 11) or Structural Heart (n = 11) on 2 test days (T1, T2). System Usability Scale (SUS) and ISONORM 9241/110-S (ISONORM) questionnaire were used after the test. The valve size selected by each beginner was compared with the valve size selected from expert group. RESULTS: Valve Assist 2 had higher SUS Score: median 78.75 (25th, 75th percentile: 67.50, 85.00) compared to Structural Heart: median 65.00 (25th, 75th percentile: 47.50, 73.75), (p < 0,001, r = 0.557). Also, Valve Assist 2 showed a higher ISONORM score: median 1.05 (25th, 75th percentile: - 0.19, 1.71) compared to Structural Heart with a median 0.05 (25th, 75th percentile: - 0.49, 0.13), (p = 0.036, r = 0.454). Correctly selected valve sizes were stable over time using Valve Assist 2: 72.73% to 69.70% compared to Structural Heart program: 93.94% to 40% (χ2 (1) = 21.10, p < 0.001, φ = 0.579). CONCLUSION: The study shows significant better usability scores for Valve Assist 2 compared to 3mensio Structural Heart in program-inexperienced users.
RESUMO
INTRODUCTION: Childhood asthma is a highly prevalent chronic disease. A failure to implement patient education programmes may result in increased morbidity, despite the availability of distinct diagnostic and therapeutic approaches. Patients with lower socioeconomic status (SES) tend to have a higher asthma prevalence. Moreover, the progression of asthma is significantly influenced by factors such as health literacy and the children's specific knowledge about the condition. With this trial, the primary objective is to evaluate whether asthma education enhances specific disease understanding in children with asthma (primary outcome). Secondary objectives include evaluating training effects on health literacy, retention rates of information, 'Children Asthma Control Test' (C-ACT) score, frequency of emergency room and physician visits (secondary outcomes) and whether SES influences training effects. METHODS AND ANALYSIS: To address the research objectives, this study comprises two projects. The first subproject will investigate the influence of asthma training on the development of disease understanding and health literacy. The second subproject will analyse the influence of SES on the outcome of children participating in asthma training. This research is designed as a comparative, non-randomised study involving two paediatric groups between the ages of ≥7 and < 14 years. After being diagnosed with asthma, the intervention group undergoes standardised psychoeducational asthma training at a certified centre associated with paediatricians in private practice in Germany, following the recommendations of the 'Arbeitsgruppe Asthmaschulung im Kindes- und Jugendalter e.V.', a national association aiming to establish uniform and guideline-based standards for patient education in children and adolescents. The comparison group receives a significantly shorter period of education and instruction on the usage of asthma medication at outpatient clinics. Data will be collected from patients and their parents at three specific survey time points, based on standardised tools.To describe mean differences between the intervention and control group over time (subproject 1), a repeated-measures analysis of variance (ANOVA) will be conducted. In subproject 2, multivariate linear regression analysis will be used to analyse the variables determining the changes in specific disease understanding and health literacy, including SES. The sample size calculation is based on a mixed ANOVA model with two groups and two measurements resulting in a total of 126 participants. ETHICS AND DISSEMINATION: All protocols and a positive ethics approval were obtained from the Witten/Herdecke University, Germany (S-159, 2023; application submission: 24 June 2023, final vote: 10 July 2023). Furthermore, the study was registered at the German Clinical Trials Register (DRKS), DRKS00032423. The application submission was on 3 August 2023, and the final approval was on 4 August 2023. The results will be disseminated among experts and participants and will be published in peer-reviewed, international journal with open access. TRIAL REGISTRATION NUMBER: DRKS00032423.

Objective: The aim of the study was to assess the current curricular status of content on infection prevention in hospitals during medical education prior to the development of a serious game on infection prevention in hospitals. In addition, the data collected was to be contrasted with the training for a specialist nurse in hygiene and infection prevention (FKHI). Methodology: In an online survey, persons in charge of medical degree programs and continuing education centers for FKHI, SkillsLabs and professional associations in Germany were asked to answer 28 questions on framework conditions, teaching, examinations, and gamification. Results: Data was collected for 22 medical degree programs and 5 FKHI continuing education centers. Due to the low response rate, the data for the FKHI was only analyzed in summary form. On average, 13.5 teaching units (median) are available in medical studies. Six degree programs have a longitudinal curriculum. In 7 of the 22 degree programs, teaching is based on the National Competency-Based Learning Objectives Catalogue (NKLM). Almost all locations teach this content in lectures (n=18) and/or in internships (n=13). Teaching and examinations are most common in the third year of study (n=12). In addition to practical OSCE examinations (n=5), written (n=12) and computer-based (n=8) examinations are used in particular. Gamification is known as a didactic approach to some extent but is not used for teaching infection prevention. Conclusions: Infection prevention in hospitals is given relatively low priority in medical education. Teaching and examinations are based on traditional knowledge-oriented formats, although practical teaching and practical examinations are established at some locations. In contrast to the FKHI, learning objectives currently appear to be less standardized. Further interprofessional development of teaching would be desirable in the future.

Objective: Medical students' health and resilience have increasingly been the subject of current research in recent years. A variety of interventions are recommended to strengthen resilience or its known or suspected influencing factors, although the literature shows that the evidence on the effectiveness of the interventions is inconsistent. The present study investigated whether gratitude is a direct protective factor for resilience in medical students or whether resilience factors (optimism, self-efficacy, social support) and stress mediate the effects of gratitude on resilience. Methods: 90 medical students at Witten/Herdecke University took part in the study that determined their gratitude, resilience, optimism, self-efficacy, social support and stress levels using validated questionnaires (GQ-6, RS-25, LOT-R, SWE, F-SozU, PSS). Correlations were analyzed using Pearson correlation coefficients. In addition, a multivariate regression analysis and a path analysis were calculated to determine the direct and indirect effects of gratitude on resilience. Results: Multivariate regression analysis showed that only optimism, social support and stress were significantly associated with resilience (B=0.48, 95% CI: 0.31, 0.66; B=0.23, 95% CI: 0.01, 0.44 and B=-0.02, 95% CI: -0.03, -0.001, respectively). The direct effect of gratitude on resilience was minimal and not significant in the path analysis. However, there was an indirect effect of gratitude on resilience (B=0.321; p<0.05). Mediation via the optimism variable was mainly responsible for this effect (indirect effect B=0.197; p<0.05). Conclusion: This study shows that gratitude has only a minimal direct influence on resilience. However, results indicate that optimism as a mediating factor strengthens the resilience of medical students. Against this background, it may be useful to integrate interventions that promote an optimistic attitude into medical studies in order to strengthen the mental health of future doctors in the long term.

Objectives: Physicians and the medical/scientific establishment during Nazism and the Holocaust committed egregious ethical violations including complicity with genocide. Critical reflection on this history serves as a powerful platform for scaffolding morally resilient professional identity formation (PIF) with striking relevance for contemporary health professions education and practice. Study aim was to explore the impact of an Auschwitz Memorial study trip within the context of a medicine during Nazism and the Holocaust curriculum on students' personal and PIF. Methods: The authors analyzed 44 medical and psychology students' reflective writings from a 2019 Auschwitz Memorial study trip using immersion-crystallization qualitative thematic analysis. Results: Six distinct themes and 22 subthemes were identified and mapped to a reflective learning process model: 1. "What am I bringing?" 2. "What am I experiencing through the curriculum?" 3. "What am I initially becoming aware of as a first response?" 4./5. "How and what am I processing?" 6. "What am I taking with me?" Particularly compelling subthemes of power of the place, emotional experience, reflection on myself as a moral person, and contemporary relevance referred to impactful course elements. Conclusions: This curriculum catalyzed a critically reflective learning/meaning-making process supporting personal and PIF including critical consciousness, ethical awareness, and professional values. Formative curriculum elements include narrative, supporting emotional aspects of learning, and guided reflection on moral implications. The authors propose Medicine during Nazism and the Holocaust curriculum as a fundamental health professions education component cultivating attitudes, values, and behaviors for empathic, moral leadership within inevitable healthcare challenges.

Casposons are transposable elements containing the CRISPR associated gene Cas1solo. Identified in many archaeal genomes, casposons are discussed as the origin of CRISPR-Cas systems due to their proposed Cas1solo-dependent translocation. However, apart from bioinformatic approaches and the demonstration of Cas1solo integrase and endonuclease activity in vitro, casposon transposition has not yet been shown in vivo. Here, we report on active casposon translocations in Methanosarcina mazei Gö1 using two independent experimental approaches. First, mini-casposons, consisting of a R6Kγ origin and two antibiotic resistance cassettes, flanked by target site duplications (TSDs) and terminal inverted repeats (TIRs), were generated, and shown to actively translocate from a suicide plasmid and integrate into the chromosomal MetMaz-C1 TSD IS1a. Second, casposon excision activity was confirmed in a long-term evolution experiment using a Cas1solo overexpression strain in comparison to an empty vector control under four different treatments (native, high temperature, high salt, mitomycin C) to study stress-induced translocation. Analysis of genomic DNA using a nested qPCR approach provided clear evidence of casposon activity in single cells and revealed significantly different casposon excision frequencies between treatments and strains. Our results, providing the first experimental evidence for in vivo casposon activity are summarized in a modified hypothetical translocation model.

OBJECTIVES: To evaluate possible associations between learners' results in written and performance-based assessments of communication skills (CS), either in concurrent or predictive study designs. METHODS: Search included four databases for peer-reviewed studies containing both written and performance-based CS assessment. Eleven studies met the inclusion criteria. RESULTS: Included studies predominantly assessed undergraduate medical students. Studies reported mainly low to medium correlations between written and performance-based assessment results (Objective Structured Clinical Examinations or encounters with simulated patients), and gave correlation coefficients ranging from 0.13 to 0.53 (p < 0.05). Higher correlations were reported when specific CS, like motivational interviewing were assessed. Only a few studies gave sufficient reliability indicators of both assessment formats. CONCLUSIONS: Written assessment scores seem to predict performance-based assessments to a limited extent but cannot replace them entirely. Reporting of assessment instruments' psychometric properties is essential to improve the interpretation of future findings and could possibly affect their predictive validity for performance. PRACTICE IMPLICATIONS: Within longitudinal CS assessment programs, triangulation of assessment including written assessment is recommended, taking into consideration possible limitations. Written assessments with feedback can help students and trainers to elaborate on procedural knowledge as a strong support for the acquisition and transfer of CS to different contexts.

Introduction: The promotion of physicians' empathy (PE) skills in medical school plays a central role in physician-patient communication. However, a significant decline in empathy among medical students during their training has been repeatedly reported. Gratitude could be a possible protective factor for PE. However, as some students do not seem to be affected by this empathy loss, this study explores the relationship between gratitude and PE. Methods: Using validated questionnaires (JSPE-S, IRI and GQ-6), 88 medical students at LMU München evaluated their self-assessed PE and gratitude. In addition, they went through four OSCE stations focusing on general medicine, in which their empathy and communication skills were assessed by simulated patients (SP) and by an assessor using the Berlin Global Rating. Correlations were analysed using Pearson's correlation coefficient and gender differences were analysed using Mann-Whitney U-tests. Results: In the self-assessment, there was a significant, moderate correlation between students' attitude towards empathy (JSPE-S) and their gratitude (GQ-6) and a weak correlation between the IRI subscale "Empathy" and the GQ-6. In terms of the performance-based assessment, there were also weak correlations between PE or communication skills and gratitude. There were no gender-specific differences in the gratitude of the students. Conclusion: We were able to demonstrate a correlational relationship between gratitude and empathy in medical students. Whether gratitude acts causally as a protective or supportive factor for empathy remains open. A causal relationship of gratitude to empathy should therefore be examined in a prospective study design.

In Germany, about two thirds of students and doctoral candidates in medicine are female. The proportion is only about 35% for post-doctoral degrees and much lower for many leadership positions at medical schools and on medical education committees. Although reasons for this have long been known, changes are slow in coming. Therefore, with this commentary, we would like to shed light on the current situation regarding gender equality in Germany in medical education and identify and discuss measures. These include, for example, mentoring and networking programs as well as greater consideration of women in committees.

OBJECTIVES: Investigate whether medical students' emotive abilities, attitudes, and cognitive empathic professional abilities predict empathic behavior in an Objective Structured Clinical Examination (OSCE). METHODS: Linear and multiple regressions were used to test concurrent validity between Interpersonal Reactivity Index (IRI), Jefferson Scale of Physician Empathy (JSPE-S), Situational Judgement Test (SJT-expert-based score (SJT-ES), SJT-theory-based score (SJT-TS)) and empathic behavior in an OSCE measured by Berlin Global Rating (BGR) and Verona Coding Definitions for Emotion Sequences (VR-CoDES). RESULTS: Highest amounts of explained variance of empathic behavior measured by VR-CoDES were found for the SJT-ES (R2 = 0.125) and SJT-TS (R2 = 0.131). JSPE-S (R2 = 0.11) and SJT-ES (R2 = 0.10) explained the highest amount of variance in empathic behavior as measured by BGR. Stepwise multiple regression improved the model for BGR by including SJT-ES and JSPE-S, explaining 16.2% of variance. CONCLUSIONS: The instrument measuring the emotive component (IRI) did not significantly predict empathic behavior, whereas instruments measuring moral (JSPE-S) and cognitive components (SJT) significantly predicted empathic behavior. However, the explained variance was small. PRACTICE IMPLICATIONS: The instrument measuring the emotive component (IRI) did not significantly predict empathic behavior, whereas instruments measuring moral (JSPE-S) and cognitive components (SJT) significantly predicted empathic behavior. However, the explained variance was small. In a longitudinal assessment program, triangulation of different instruments assessing empathy offers a rich perspective of learner's empathic abilities. Empathy training should include the acquisition of knowledge, attitudes, and behavior to support learner's empathic behaviors.

OBJECTIVE: The aim of this scoping review was to investigate the published literature on written assessment of communication skills in health professionals' education. METHODS: Pubmed, Embase, Cinahl and Psychnfo were screened for the period 1/1995-7/2020. Selection was conducted by four pairs of reviewers. Four reviewers extracted and analyzed the data regarding study, instrument, item, and psychometric characteristics. RESULTS: From 20,456 assessed abstracts, 74 articles were included which described 70 different instruments. Two thirds of the studies used written assessment to measure training effects, the others focused on the development/validation of the instrument. Instruments were usually developed by the authors, often with little mention of the test development criteria. The type of knowledge assessed was rarely specified. Most instruments included clinical vignettes. Instrument properties and psychometric characteristics were seldom reported. CONCLUSION: There are a number of written assessments available in the literature. However, the reporting of the development and psychometric properties of these instruments is often incomplete. Practice implications written assessment of communication skills is widely used in health professions education. Improvement in the reporting of instrument development, items and psychometrics may help communication skills teachers better identify when, how and for whom written assessment of communication should be used.

Situational judgment tests (SJTs) are often used in aptitude testing and present practice-specific challenges. Their implementation into online training programs provides the opportunity to assess learning progress and improve training quality. In this study, text-based SJTs for oncology physicians were developed, validated, and implemented into the KOKON-KTO training which uses a blended learning training format to teach oncology physicians how to consult cancer patients on complementary and integrative medicine (CIM). The SJT was implemented to measure the e-learning results. In the development and validation phase, a total of 15 SJTs (each SJT including 1 best choice answer based on training content and 4 distractors; 9 SJTs for oncologists and 6 SJTs for oncology gynecologists only) were developed by an interprofessional team (n=5) using real-case vignettes and applying an in-depth review process. Best answers were validated by experts (oncologists and oncology gynecologists) with experience in advising cancer patients on CIM. In the implementation and evaluation phase, SJTs were answered by KOKON-KTO training participants (n=19) pre- and post e-learning. Results were analyzed using descriptive measurements, item difficulties, and Cohen's d for effect size pre- and post-training. The experts (n=12, 49.8% gynecologists) agreed with best choice answers (69.4% for oncology gynecology; 81.5% for oncology) in 12 out of 15 SJTs. Comparing pre- and post-training scores, KOKON-KTO training participants were able to improve knowledge substantially (effect sizes for oncologists d=1.7; oncology gynecologists d= .71). Future studies need to increase the number of experts and SJTs in order to apply further psychometric measurements. As part of the KOKON-KTO study, this project is registered as DRKS00012704 on the "German Clinical Trials Register" (Date of registration: 28.08.2017).

The commentary deals with the question of what constitutes communicative competence (or communication skills) and to what extent findings regarding motor and social skills are transferable to the domain of communication. After a proposal for a definition, the commentary considers how learners acquire communicative competence and what needs to be considered from the trainers' perspective in order to support learners in their competence development. The commentary does not claim to present all definitions of the concept of competence or communicative competence in a comprehensive way. Nor does it aim to present the current state of research. Our aim is to provide teachers and interested individuals in medical education with a pragmatic guide to how communicative competence can be taught and learned based on a skills model.

Background: In October 2018, the University of Witten/Herdecke (UW/H) launched the new reformed medical education programme called Medicine 2018+. A major innovation compared to the existing model programme was the introduction of thematic focuses. A longitudinal communication skills curriculum was integrated into the new thematic focus "professional and personal development - inner work" (IAP). With the start of the new programme, the IAP curriculum has been built step-by-step over time, i.e. the first four semesters have already been implemented, the following semesters are being planned. Project description: IAP aims to provide students with patient-centred medicine. Five areas of competence were defined: Doctor-patient communication, team competence, staying healthy, my paths to becoming a doctor, medicine and society. The focus of this article is on the communication curriculum. The first year of study focusses on the training of basic communication skills. In the 2nd year of study, students practice these basic skills in small groups with simulated patients (SP), whereby the emphasis in the 3rd semester is on history taking and in the 4th semester is on sharing information. In the 3rd semester, students complete a communication station in an OSCE. From the 5th semester onwards, the focus of training is on the consolidation of basic and advanced communication skills, which can be applied in clinical clerkships, and the reflection of clinical experiences. Key didactic elements are, in addition to teaching the theoretical basics, experience-based small group work with and without SP, feedback and reflection. The evaluation of the summer semester 2020 showed high agreement ratings of the students regarding the overall satisfaction with the individual courses (83-100% agreement). Discussion: The introduction of IAP has been very positively received by the students. Challenges are the adequate handling of the increasing student workload when planning new courses, the implementation of a longitudinal e-portfolio as well as the recruitment and training of clinical teachers and SPs. Conclusion: As the evaluation results of the summer semester 2020 show, the first steps of implementing a longitudinal communication curriculum at UW/H have been successful. Helpful strategies were the orientation on published examples from other faculties as well as regular feedback and discussions with students and teachers in order to adapt and integrate educational considerations into the existing model programme in Witten.

Small ORF (sORF)-encoded small proteins have been overlooked for a long time due to challenges in prediction and distinguishing between coding- and noncoding-predicted sORFs and in their biochemical detection and characterization. We report on the first biochemical and functional characterization of a small protein (sP26) in the archaeal model organism Methanosarcina mazei, comprising 23 amino acids. The corresponding encoding leaderless mRNA (spRNA26) is highly conserved on nucleotide level as well as on the coded amino acids within numerous Methanosarcina strains strongly arguing for a cellular function of the small protein. spRNA26 level is significantly enhanced under nitrogen limitation, but also under oxygen and salt stress conditions. Using heterologously expressed and purified sP26 in independent biochemical approaches [pull-down by affinity chromatography followed by MS analysis, reverse pull-down, microscale thermophoresis, size-exclusion chromatography, and nuclear magnetic resonance spectroscopy (NMR) analysis], we observed that sP26 interacts and forms complexes with M. mazei glutamine synthetase (GlnA1 ) with high affinity (app. KD = 0.76 µm± 0.29 µm). Moreover, seven amino acids were identified by NMR analysis to directly interact with GlnA1 . Upon interaction with sP26, GlnA1 activity is significantly stimulated, independently and in addition to the known activation by the metabolite 2-oxoglutarate (2-OG). Besides, strong interaction of sP26 with the PII-like protein GlnK1 was demonstrated (app. KD = 2.9 µm ± 0.9 µm). On the basis of these findings, we propose that in addition to 2-OG, sP26 enhances GlnA1 activity under nitrogen limitation most likely by stabilizing the dodecameric structure of GlnA1 .

Since October 2018, a longitudinal communication curriculum for medical students has been implemented at Witten/Herdecke University. In the summer semester 2020, the concept for the 4th preclinical semester included a practical training on "sharing information", which consisted of three two-hour face-to-face sessions with simulated patients (SP). Due to the Covid 19 pandemic, teaching was changed to an inverted classroom concept combining asynchronous and synchronous teaching. The students worked at the beginning of the semester on an e-learning module of the learning platform docCom.deutsch on the topic "sharing information" using reflection and processing tasks. In two digital sessions, the students then were able to practice discharge interviews and discussions about risk communication illustrated by the example of screening methods for cancer prevention. In the first zoom session, students practiced in role-plays among themselves. In the second zoom session, they practiced with SP. The evaluation results revealed that 76% of the responding students considered working with the e-learning module as a good preparation for the interviews. According to the evaluation results, satisfaction with the Zoom meeting including SP contact was slightly higher than those with role-plays among themselves. Although the group atmosphere was rated by all responding students as conducive to learning, almost half of them confirmed that using Zoom significantly impaired the atmosphere (47%). In retrospect, the conversion of the communication training to a digital format worked better than expected from both the perspective of teachers and students. The students explicitly appreciated working with SP. From the teachers' perspective, some specific aspects of successful communication were difficult to reflect on, e.g. non-verbal communication. The use of e-learning as a preparation for practical exercises has proven successful and will be continued in the future.

Background: As a teaching method, feedback is an integral part of medical education. However, there is a lack of a uniform theoretical basis or generally recognized guidelines for its specific design. Against this background, the aim of this article is to discuss conceptual considerations and empirical findings regarding feedback using various practical examples. Procedure and conceptual considerations: Building on the results of a workshop of the Committee for Communicative and Social Competences of the Society for Medical Education (GMA), this article first explains central conceptual considerations and empirical results on the topic of feedback. A particular focus is on various variables that influence the effect of feedback. This includes the feedback source, the frequency of feedback, starting points of feedback, the connection between feedback and reflection as well as the motivation and meta-cognitive skills of the feedback recipient. Practical examples: The implementation of feedback in practice is illustrated using eight examples from the field of medical and dental education. They stem from various settings and the focus is on formative oral feedback. It will become evident that the focus is more on the givers of feedback than the recipients of feedback. Instructions for recipients of feedback on how to reflect on it is still the exception. Discussion: Many of the relevant aspects for the effect of feedback described in the literature are already taken into account in the practical examples discussed. In conclusion, seven recommendations are made for implementing feedback in practice.

Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR) loci are found in bacterial and archaeal genomes where they provide the molecular machinery for acquisition of immunity against foreign DNA. In addition to the cas genes fundamentally required for CRISPR activity, a second class of genes is associated with the CRISPR loci, of which many have no reported function in CRISPR-mediated immunity. Here, we characterize MM_0565 associated to the type I-B CRISPR-locus of Methanosarcina mazei Gö1. We show that purified MM_0565 composed of a CRISPR-Cas Associated Rossmann Fold (CARF) and a winged helix-turn-helix domain forms a dimer in solution; in vivo, the dimeric MM_0565 is strongly stabilized under high salt stress. While direct effects on CRISPR-Cas transcription were not detected by genetic approaches, specific binding of MM_0565 to the leader region of both CRISPR-Cas systems was observed by microscale thermophoresis and electromobility shift assays. Moreover, overexpression of MM_0565 strongly induced transcription of the cas1-solo gene located in the recently reported casposon, the gene product of which shows high similarity to classical Cas1 proteins. Based on our findings, and taking the absence of the expressed CRISPR locus-encoded Cas1 protein into account, we hypothesize that MM_0565 might modulate the activity of the CRISPR systems on different levels.

OBJECTIVE: Emotion-handling skills are key components for interpersonal communication by medical professionals. The Verona Coding Definitions of Emotional Sequences (VR-CoDES) appears useful to develop a Situational Judgment Test (SJT) for assessing emotion-handling skills. METHODS: In phase 1 we used a multi-stage process with expert panels (npanel1â¯=â¯16; npanel2â¯=â¯8; npanel3â¯=â¯20) to develop 12 case vignettes. Each vignette includes (1) video representing a critical incident containing concern(s) and/or cue(s), (2) standardized lead-in-question, (3) five response alternatives. In phase 2 we piloted the SJT to assess validity via an experimental study with medical students (nâ¯=â¯88). RESULTS: Experts and students rated most of the 'Reduce space' responses as inappropriate and preferred 'Explicit' responses. Women scored higher than men and there was no decline of empathy according to students' year of study. There were medium correlations with self-assessment instruments. The students' acceptance of the SJT was high. CONCLUSION: The use of VR-CoDES, authentic vignettes, videos and expert panels contributed to the development and validity of the SJT. PRACTICE IMPLICATIONS: Development costs were high but could be made up over time. The agreement on a proper score and the implementation of an adequate feedback structure seem to be useful.
