The Effectiveness of Psychotherapies in Suicide Ideation and Behavior—An Expert Review

Historically, the evidence base for psychotherapies specifically effective against suicidality has been limited; however, recent large meta-analyses have begun to change this picture. Current debate centers on which interventions demonstrate robust efficacy and the mechanisms through which they exert therapeutic benefit. Accumulating studies indicate that some psychotherapies reduce suicidal ideation and behavior. Despite these advances, recent empirical work directly mapping and comparing these interventions as well as elucidating their shared elements remains limited. This evidence-informed expert narrative review synthesizes findings from recent randomized clinical trials and systematic reviews with meta-analyses, and is complemented by a comparative analysis of therapeutic strategies. The objective is to identify psychotherapies with demonstrated effectiveness in suicide prevention and to delineate the common processes underlying clinical improvement. Recognizing these cross-cutting mechanisms may inform the development of interventions that retain efficacy while enhancing scalability in routine care. Such efforts hold potential to advance clinical practice and orient future research agendas in suicidology.
