The Effectiveness of Group Therapy for Substance Use Disorders: A Meta-Analysis of Randomized Controlled Trials
Abstract
Group therapy has long been recognized as a valuable intervention for individuals with substance use disorders, offering a supportive environment for peer interaction and shared experiences. This meta-analysis of randomized controlled trials (RCTs) evaluates the efficacy of group therapy in reducing substance use and improving overall functioning in individuals with substance use disorders. Through a comprehensive review of the literature, the meta-analysis synthesizes effect sizes from RCTs assessing the effectiveness of group therapy compared to control conditions (e.g., individual therapy, treatment as usual) in targeting substance use frequency, severity of dependence, cravings, and psychosocial functioning. Additionally, it examines potential moderators of treatment outcomes, such as treatment duration, group size, therapist involvement, and participant characteristics (e.g., substance of abuse, comorbidities), to better understand the factors influencing the effectiveness of group therapy for substance use disorders.
