The aim of this qualitative research was to gather data about young people's experiences of depression stigma and its impact on loneliness, social isolation, and mental health disclosure and secrecy. This novel information can then be used to guide psychosocial interventions for young people with depression. This study provides new evidence of how young people with depression experience stigma and its effects on disclosure and mental health secrecy. Knowing how young people struggle with these issues can allow us to develop interventions to encourage them to come forward and discuss their mental health in order to receive appropriate support and treatment. We recommend young people be signposted and have access to mental health champions or nominated teachers in their schools or universities.
