Ethics approval and consent to participate
: The present project was approved by the Norwegian Centre for Research Data (NSD: approval no. 52648). The Norwegian Centre for Research Data ensures that data about people can be collected, stored and shared, both safely and legally, today and in the future. The Ethical Committee of South East Norway provides advance approval for medical and health research projects involving humans. As this project is not a medical nor health research project, approval from The Ethical Committee of South East Norway was not required. Informed consent was obtained from all participants. Information was provided to the informants on both occasions when they participated in the study. At baseline they received information both orally and on a written handout, and at the follow-up point via e-mail. The students were also informed about participant anonymity and their right to withdraw from the study at any time, without giving any reason. All methods were implemented in accordance with the EU’s General Data Protection Regulation (Regulation 2016/679), and the study adhered consistently to STROBE guidelines.
