Highlight
– A comprehensive 2025 systematic review of 65 studies (14,534 youths) found only moderate-strength evidence that dialectical behavior therapy (DBT) reduces suicidal ideation in adolescents; other psychosocial treatments provide low or insufficient evidence for suicidal outcomes.
– Acute brief interventions, school- and community-based programs, and pharmacologic, neurotherapeutic, and emerging therapies remain inadequately studied in youths at heightened suicide risk.
