Efficacy of DBT for Substance Abuse and Co-Occurring Disorders
DBT consistently shows positive outcomes for individuals with substance abuse and co-occurring mental health issues.
Randomized controlled studies conducted with people with borderline personality disorder have demonstrated a consistent reduction in self-harm and suicidal behavior, as well as a reduction in substance use and hospitalizations when compared to treatment-as-usual controls.[5] Since BPD so frequently co-occurs with substance use disorder (nearly 80% of those with BPD will develop a substance abuse disorder at some point in their lives), these findings have direct relevance to addiction treatment.[6]
Studies focusing on DBT in substance use disorder have demonstrated meaningful reductions in drug use, cravings, and relapse rates. Research conducted by Dr. Marsha Linehan and colleagues found that DBT resulted in a greater reduction in substance use than standard treatment among women with BPD and a substance abuse disorder, with results that were sustained at follow-up.[7] Similar findings have been replicated with varying populations since that time.
DBT has also been successful in reducing symptoms associated with co-occurring disorders commonly seen with substance use disorders, including PTSD, eating disorders, bipolar disorder, and depression, making it a valuable treatment option in a dual diagnosis setting.[8] For clients managing multiple co-occurring conditions alongside addiction, DBT’s broad applicability makes it one of the most versatile and impactful therapies available.
The evidence overwhelmingly shows that DBT provides valuable and powerful tools for persons with emotional dysregulation that feeds addiction and provides individuals with the ability to build a life of wellness and stability.
