Abstract
Adolescent suicide is a serious public health problem, and non-suicidal self-injury (NSSI) is both highly comorbid with suicidality among adolescents and a significant predictor of suicide attempts (SAs) in adolescents. We will clarify extant definitions related to suicidality and NSSI and the important similarities and differences between these constructs. We will also review several significant risk factors for suicidality, evidence-based and evidence-informed safety management strategies, and evidence-based treatment for adolescent self-harming behaviors. Currently, dialectical behavior therapy (DBT) for adolescents is the first and only treatment meeting the threshold of a well-established treatment for self-harming adolescents at high risk for suicide. Areas in need of future study include processes underlying the association between NSSI and SAs, clarification of warning signs and risk factors that are both sensitive and specific enough to accurately predict who is at imminent risk for suicide, and further efforts to sustain the effects of DBT post-treatment. DBT is a time- and labor-intensive treatment that requires extensive training for therapists and a significant time commitment for families (generally 6 months). It will therefore be helpful to assess whether other less-intensive treatment options can be established as evidence-based treatment for suicidal adolescents.
