Suicide Among Adolescents: Prior Use of Psychiatric Services and Opportunities Offered by Digital Prevention Programs Abstract: Suicide prevention in adolescence poses a challenge to society as a whole, in which child and adolescent psychiatry plays a central role in view of the high prevalence of mental disorders among suicides. But how often do adolescents actually seek psychiatric help before committing suicide? This review looks at contact rates with psychiatry and other institutions prior to suicide. It examines how nonlethal suicide attempts often precede suicide as a "warning signal," and which individual and structural barriers prevent young people from seeking psychiatric help. Furthermore, it discusses whether messenger-based prevention programs reach those adolescents who do not seek psychiatric care. This review highlights existing gaps in care and identifies possible starting points for digital prevention strategies in practice.
