Comparing treatments for dual diagnosis: twelve-step and self-management and recovery training

The purpose of this study was to compare the effectiveness of 12-step and cognitive-behavioral (Self-Management and Recovery Training [SMART]) approaches for persons with a dual diagnosis of serious mental illness and substance use disorder in an intensive outpatient/partial hospitalization setting. Participants (n = 112) were alternately assigned to the two treatment conditions, with 50 participants completing the 6-month treatment program. Assessments occurred at baseline, 3 months, and 6 months during treatment, and at 3- and 12-month follow-ups. Analyses were conducted on participants who had completed 3 months of treatment (n = 70). The 12-step intervention was more effective in decreasing alcohol use and increasing social interactions. However, a worsening of medical problems, health status, employment status, and psychiatric hospitalization were associated with the 12-step intervention. SMART was more effective in improving health and employment status, but marijuana use was greater for SMART participants. Improvements in alcohol use and life satisfaction occurred in both approaches. Covariates associated with treatment outcome were identified, with greater attendance being positively related to outcome. Involvement with the criminal justice system was positively related to treatment completion but negatively associated with medical problems. Less alcohol use, fewer medical problems, and better financial well-being at baseline were associated with better attendance.
