Establishing Efficacy of an Inpatient Intervention and Phone App to Reduce Suicidal Risk

The investigators aim to randomize 240 adolescents psychiatrically hospitalized for suicidal ideation with a plan or a suicide attempt to one of four treatment arms: (1) ASAP + BRITE + TAU (treatment as usual); (2) BRITE + TAU (treatment as usual); (3) ASAP + TAU (treatment as usual); and (4) TAU (treatment as usual) alone. The investigators will assess suicidal ideation and behavior at 4, 12, and 24 weeks post‐intake, in order to: 1. Assess the relative efficacy of ASAP, BRITE and the combination on suicidal ideation, non‐suicidal self‐injury (NSSI), and suicide attempts, and re‐hospitalizations. 2. Examine mediators and moderators of treatment outcome. 3. Examine the costs and cost efficacy of ASAP and BRITE and the combination.
