Ethics approval and consent to participate

: The study was approved by the Ethics Committee of the Faculty of Health, Medicine and Life Sciences, Maastricht University, on 23 October 2017 (reference number: Steenaart/231017) and registered at the Dutch Trial Register (NTR6771;). Students provided written informed consent after explanations about the study, had the opportunity to withdraw their consent at any time, and were informed of the anonymous way in which their data would be processed. They were provided with contact information in case they had any further questions.Parents of participants were not informed about the program or the research connected to this. The content of the curriculum that students follow is decided on by the schools, which means that no consent from parents is needed for the actual program. Parental consent was, therefore, only considered for the questionnaire that students filled out. This was, however, not seen as necessary as all students were above the age of 16 years and the large majority was above the age of 18 years. Moreover, practical difficulties made it impossible to reach the parents in this type of schooling.

: Written informed consent for publication of their details was obtained from the students. A copy of the consent form is available for review by the Editor of this journal.
