: All methods were carried out in accordance with relevant guidelines and regulations. Data collection was anonymous. Students were informed that completion and return of questionnaires was voluntary, and that non-participation had no negative consequences for attendance at the LW nor potential proof of performance. Participants were free to decide how much time to invest in completing the questionnaire, how detailed their answers should be, and how much personal information they were willing to give. Thus, informed consent to participate was given (Additional file InternalRef removed). A vote of approval was obtained from the Ethics Committee of Witten/Herdecke University <i>(submission no. 205/December 2019)</i>.
