Students in medicine, dentistry and biology will be approached by their lecturers with an invitation to volunteer to participate in a questionnaire survey on living conditions and mental health. To strengthen the chance of gaining 200 volunteers over a short time-period, students will also be able to forward the link to their peers. I will target students in health-related programs, because the psychological intensity of the health sector is more than likely to have a strong negative impact on these students’ mental health (Huang et al., 2020). To be included, students must be aged from 18 to 35 years and, to ensure that they are familiar with their neighbourhood environment, must have lived in their current home for at least six months. Participants will need to confirm that they are at least 18 years old and provide informed consent on the survey form, thereby agreeing that their personal information will be processed and stored according to the General Data Protection Regulation in the European Union.
