Effect of a One-Time Communication Training Session on Dental Students' Self-Efficacy Expectancy.

An implementation of training units that provide evidence for improving students' communication skills in the dental curriculum is now more than ever of utmost importance. This study aimed to investigate how students assess their skills after communication training and whether this training also increased students' self-efficacy expectancy. A total of 32 male and 71 female students with a mean age of 25.6 ± 3.9 years participated in the study. Self-assessment of communication skills and self-efficacy expectancies were collected at two time points using Likert scales. Our study shows that the communication training, consisting of a practical exercise with actors and an online theory module, significantly improved the students' self-assessment of their communication skills and also improved some aspects of self-efficacy expectancy. These results indicate that, in addition to the practical and technical-theoretical training of students, communication training is essential in the dental curriculum. In summary, this study showed that a one-time practical exercise with actors together with an online theory module could improve both the self-assessment of communication competence and some aspects of self-efficacy expectancy, which demonstrates the importance of training communication skills alongside practical and technical-theoretical training.

Development and testing of a summative video-based e-examination in relation to an OSCE for measuring communication-related factual and procedural knowledge of medical students.

Objective: In the context of educating medical students, testing of competence in medical communication is carried out primarily with the Objective Structured Clinical Examination [1]. This makes it possible to assess practical performance, but it is resource-intensive and has a negative impact on test quality. The project "Digital test tool for measuring communication skills in medical studies" (digiRole) was funded by the BMBF (Federal Ministry of Education and Research) and its objective was to develop digital formats as electronic versions of an OSCE in order to test the communication competency of medical students. Such digital forms of examination should be cost-effective, be relevant to clinical practice and have high psychometric quality. In terms of content, the examination questions should incorporate factual and procedural knowledge as components of communication competency, although we assumed that procedural knowledge is more relevant than facutal knowledge to OSCE performance. This article describes the development and testing of a video-based, communication-related e-examination that is relevant to passing the test, which is the first milestone of the overall project. Methodology: We produced videos and related exam questions in the form of a situational judgement test [2] related to medical psychology and medical sociology, based on the educational content of a preclinical course on doctor-patient communication at the Mainz University Medical Center. In the summer semester of 2018, 226 students sat for this video-based single-choice e-examination (VSE). In the winter semester of 2018/2019, a different cohort of 192 students participated in the VSE as well as a tried-and-tested communication OSCE with five stations [3]. Results: The internal consistencies for the VSE in the summer semester of 2018 were α=.55, in the winter semester 2018/19 with α=.62 and for the OSCE with α=.60. There was a positive correlation between the performance of the students with the VSE and that with the OSCE (r=.21, p≤.01). Principal Axis Analyses did not reveal any dimensioning in terms of factual and procedural knowledge. In the evaluation, the majority of the students stated that the VSE was quite relevant to the practise of medical communication and were in favour of retaining this form of examination. Conclusion: The correlation between the VSE and the OSCE is relatively low, so that the VSE in this form is not a satisfactory predictor of an OSCE result. In terms of internal consistency, the VSE and the OSCE produced an almost identical result. It can also be assumed that the VSE can achieve a high degree of objectivity with the use of standardised video-based examinations as well as greater resource efficiency than OSCEs.
