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.</p>","PeriodicalId":42806,"journal":{"name":"Journal of the Korean Academy of Child and Adolescent Psychiatry","volume":"37 1","pages":"22-32"},"PeriodicalIF":1.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12782989/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145953167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It includes physical, verbal, relational, sexual, and cyber forms involving perpetrators, victims, and bully-victims. This narrative literature review synthesizes findings from studies published between 2000 and 2024 across disciplines including psychology, education, public health, and law. Data were sourced from PubMed, Scopus, and Google Scholar, focusing on global and Indonesian contexts. Bullying arises from a combination of individual traits (e.g., impulsivity and poor emotional regulation), family dynamics (e.g., insecure attachment and low cohesion), and school and cultural influences. Theoretical frameworks such as the social learning and attachment theories help explain how bullying behaviors are learned and reinforced. Neurobiologically, bullying acts as a chronic stressor that dysregulates the hypothalamic-pituitary-adrenal axis, thereby increasing the vulnerability to anxiety, depression, and behavioral disorders. Legally, many countries, including Indonesia, have implemented child protection laws that emphasize restorative justice. Interventions such as Mindfulness-Based Cognitive Therapy for Children, Cognitive-Behavioral Play Therapy, and school-based programs such as KiVa and Olweus have effectively reduced bullying and promoted psychosocial well-being. Addressing bullying requires a comprehensive multilevel approach that integrates psychological, educational, familial, and legal strategies.
