The study examines dance teachers' perceptions of how mental illness among adolescence can affect the role of teachers, what knowledge these teachers feel they have when they deal with these young people and where this knowledge comes from. Through semi-structured interviews which were analysed with thematic analysis and memo-writing, it emerged that the teachers feel that the role of the teacher is affected on a personal and professional level. They felt that they have the knowledge to deal with mental illness in adolescence but request more knowledge in the subject. The results of the study show the complex role of the teacher and indicate that teachers want more knowledge regarding mental illness among adolescents in order to better respond to these young people, but also that more research in the field is needed.
