Evidence Base Update of Psychosocial Treatments for Self-Injurious Thoughts and Behaviors in Youth

Abstract

The current review provides an evidence base update of psychosocial treatments for self-injurious thoughts and behaviors (SITBs) in youth. A systematic search was conducted of 2 major scientific databases (PsycInfo and PubMed) and ClinicalTrials.gov for relevant randomized controlled trials (RCTs) published prior to June 2018. The search identified 26 RCTs examining interventions for SITBs in youth: 17 were included in the 2015 review and 9 trials were new to this update. The biggest change since the prior review was the evaluation of Dialectical Behavior Therapy for adolescents (DBT-A) as the first Level 1: Well-established intervention for reducing deliberate self-harm (composite of nonsuicidal and suicidal self-injury) and suicide ideation in youth and Level 2: Probably efficacious for reducing nonsuicidal self-injury and suicide attempts. Five other interventions were rated as Level 2: Probably efficacious for reducing SITBs in youth, with the new addition of Integrated Family Therapy. This evidence base update indicates that there are a few promising treatments for reducing SITBs in youth. Efficacious interventions typically include a significant family or parent training component as well as skills training (e.g., emotion regulation skills). Aside from DBT-A, few treatments have been examined in more than one RCT. Given that replication by independent research groups is needed to evaluate an intervention as Well-established, future research should focus on replicating the five promising interventions currently evaluated as Probably efficacious. In addition, an important future direction is to develop brief efficacious interventions that may be scalable to reach large numbers of youth.
