Suicide is a leading cause of death among young people and an escalating public health crisis. To assess the effectiveness and harms of available treatments for suicidal thoughts and behaviors among youths at heightened risk for suicide. A systematic review was conducted searching databases including MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Scopus, and various gray literature sources from January 1, 2000, to September 26, 2024. We included randomized clinical trials, comparative observational studies, and before-after studies of psychosocial interventions, pharmacologic interventions, neurotherapeutics, emerging therapies, and combination therapies. Eligible patients were youths (aged 5-24 years) with heightened risk for suicide, adolescents from racial and ethnic minority groups known to be at increased risk of suicide, or those exposed to crime or violence. Pairs of independent reviewers selected and appraised studies. This review included 65 studies (33 randomized clinical trials, 13 comparative observational studies, and 19 before-after studies) reporting on 14 534 patients (median age, 15.1 years; 75.1% female patients). Psychosocial interventions comprised psychotherapy interventions (33 studies; cognitive behavioral therapy, dialectical behavioral therapy, collaborative assessment and management of suicidality, dynamic deconstructive psychotherapy, attachment-based family therapy, and family-focused therapy), acute (ie, 1-4 sessions or contacts) psychosocial interventions (19 studies; safety planning, family-based crisis management, motivational interviewing crisis interventions, continuity of care after crisis, and brief adjunctive treatments), and school- or community-based psychosocial interventions (13 studies; social network interventions, school-based skills interventions, suicide awareness or gatekeeper programs, and community-based, culturally tailored adjunct programs). Dialectical behavior therapy showed moderate strength of evidence for reducing suicidal ideation. Other categories of psychosocial treatments showed insufficient to low strength of evidence for reducing suicidal outcomes. None of the studies evaluated adverse events. The evidence base on pharmacologic treatment for youths at risk of suicide was largely nonexistent. This systematic review found that the current evidence on available interventions targeting youths at heightened risk of suicide is uncertain. Medication, neurotherapeutics, and emerging therapies remain unstudied among this population. The limited evidence base calls for the development of novel, developmentally and trauma-informed treatments, as well as multilevel interventions to target the increasing suicide risk among youths.
