Recent scholarship suggests treatment effects from cognitive behavioral therapy (CBT) based interventions can significantly reduce rates of prison misconduct. However, these findings may overestimate CBT treatment effects due to publication bias towards positive results and limitations of nonexperimental methodologies. This study used propensity score matching (PSM) to evaluate the effectiveness of a CBT-based substance abuse program in reducing misconduct at a northeastern correctional facility. Disciplinary outcomes were compared between program graduates (n = 156) and non-graduates (n = 482). Despite observable differences between groups before PSM, results indicated no significant treatment effects on misconduct after matching. Research and policy implications are discussed.
