Integrated treatment of posttraumatic stress disorder and substance use disorders for adolescents and youth: current evidence and future directions
AI Summary
Integrated, trauma-focused psychotherapies for adolescents with co-occurring PTSD and substance use disorders appear safe and show promising symptom and substance use improvements.
Risk Reduction Through Family Therapy (RRFT) has multiple randomised controlled trials showing durable PTSD and substance use benefits; COPE-A has preliminary support.
Evidence is limited by small samples, intervention heterogeneity, and scarce long-term and implementation data; larger trials and mechanistic research are needed.
Background: Posttraumatic stress disorder (PTSD) and substance use disorders (SUD) frequently co-occur during adolescence and are associated with substantial functional impairment and elevated risk for chronic comorbidity. Despite strong evidence supporting integrated, trauma-focused treatments for adults with PTSD + SUD, the adolescent treatment literature remains limited.Objective: This review synthesizes current evidence on the integrated treatments for co-occurring PTSD + SUD problems among adolescents and youth, with emphasis on evaluating the strength of the evidence and identifying key directions for future research.Method: Targeted searches identified randomized controlled trials, open trials, pilot studies, and feasibility studies evaluating treatments for adolescents with PTSD + SUD problems. Studies were included if they reported PTSD and/or substance use outcomes. Findings from the adult PTSD + SUD literature were reviewed to inform developmentally appropriate adaptation for youth.Results: The adolescent evidence base is sparse. Risk Reduction Through Family Therapy (RRFT) is the only integrated treatment supported by multiple randomized controlled trials, demonstrating durable improvements in PTSD symptoms and substance use. Preliminary evidence also supports Concurrent Treatment of PTSD and Substance Use Disorders Using Prolonged Exposure for Adolescents (COPE-A). Across studies, trauma-focused treatment was not associated with increased substance use and was generally acceptable to adolescents. However, conclusions are constrained by small samples, heterogeneous interventions, and limited long-term and implementation data.Conclusions: Integrated, trauma-focused psychotherapies appear safe and promising for adolescents with co-occurring PTSD + SUD problems. Larger trials, mechanistic research, and implementation-focused studies are needed to inform best practices and expand access to effective care.
