Editorial: Dialectical Behavior Therapy and the Function of Self-Injury.

The study by Asarnow et al. is the third major paper from a large, federally funded, randomized, controlled trial of dialectical behavior therapy (DBT) as compared to Individual and Group Supportive Therapy (IGST) for reducing self-injury in teens. The first paper established the superiority of DBT as compared to IGST. The second paper focused on predictors and moderators of treatment outcome. The goal of this, the third, publication is to identify the mechanism by which DBT is effective in reducing suicidal and self-injurious behavior in an at-risk group of adolescents. The value of DBT in reducing suicidal behavior is increasingly important as we face what appears to be a rise in attempt rates and suicide deaths during the COVID-19 pandemic..
