Evidence-Based Psychotherapy for Disruptive Behavior Disorders.

Disruptive behavior disorder (DBD), which includes oppositional defiant disorder and conduct disorder, is among the most common externalizing disorders in childhood and adolescence. This review aimed to identify evidence-based psychotherapies for DBD and summarize their empirical foundations and characteristics. We searched for randomized controlled trials and systematic reviews using PubMed, PsycINFO, and Google Scholar, focusing on major evidence-based guidelines from the National Institute for Health and Care Excellence (NICE), American Psychological Association (APA), and Agency for Healthcare Research and Quality (AHRQ). Six interventions demonstrated the strongest empirical support: Incredible Years, Triple P, Parent-Child Interaction Therapy, Parent Management Training-Oregon Model, Multisystemic Therapy, and Treatment Foster Care-Oregon Model. These programs share a behavioral foundation that emphasizes parent-centered interventions as the core therapeutic mechanism. Considering treatment resistance and legal implications, multisystemic and community-based approaches are recommended for adolescents with severe antisocial behavior. In Korea, existing studies have primarily applied cognitive-behavioral, child-focused, and group interventions with limited fidelity assessments and few parent-focused trials. Future priorities include disseminating and validating parent-based behavioral therapies, establishing long-term follow-up systems, and adapting digital or telehealth platforms to enhance accessibility. Strengthening evidence-based, scalable behavioral interventions is crucial for improving the outcomes of Korean youths with DBD.
