Data collection
Evaluation questionnaires were distributed in paper form as part of the closure session of the course. The questionnaire can be found under supplementary files (Mindfulness questionnaire). Participation was open to every employee who had attended the course in full or in part. Conducting the survey took place as part of a routine quality assurance survey. Therefore, all course participants were included and a high response rate could be expected even if participation was voluntary. The sample corresponds to the description of the participants. Additional questionnaires were accessible for later participation and further participants respectively. As in every regular course evaluation, participation was voluntary and anonymous. In a timeframe of two weeks, the evaluation questionnaires were collected in a box ensuring that no tracing of the participants was possible. With their submission, the participants gave their consent to the evaluation. For the retrospective scientific analysis of the routine evaluation, a positive vote of the appropriate ethics committee is available.
