Effective psychosocial therapies treat self-injurious thoughts and behaviors in youth
Over the past two decades, research on psychosocial treatments for self-injurious thoughts and behaviors (SITBs) in youth has grown substantially. Clinicians and families now have more options than ever before, including therapies designed specifically to reduce suicidal ideation, suicide attempts, and nonsuicidal self-injury. Still, the field continues to ask an important question: which treatments have the strongest evidence, and for whom do they work best? As rates of youth suicide and self-harm remain elevated, regularly updating the evidence base is essential to ensure that prevention and intervention efforts are grounded in the most rigorous and current science.
With an updated review covering studies published between 2018 and 2024, Dr. Catherine Glenn and her team evaluated the strength of evidence for psychosocial treatments targeting self-injurious thoughts and behaviors in children and adolescents. Building on prior evidence reviews, she examined randomized controlled trials and other rigorous evaluations to determine which approaches meet criteria for well-established, probably efficacious, or possibly efficacious treatments. The findings indicate that several structured, skills-based therapies, particularly those incorporating cognitive behavioral and dialectical behavior therapy components, continue to show the strongest support for reducing suicidal behaviors and self-harm in youth. Family involvement and emotion regulation skill-building emerged as common and important elements across effective interventions. At the same time, the review highlighted ongoing gaps, including limited replication studies, variability in outcome measurement, and the need for more research in diverse populations and real-world clinical settings. Overall, evidence-based psychosocial treatments can meaningfully reduce risk for self-injurious thoughts and behaviors in youth, while underscoring the importance of continued refinement and implementation research.
