12-Step approaches for the dually diagnosed: Mechanisms of change

Abstract

Background: Existing data indicate that 12-step program involvement is associated with improved outcomes in the dually diagnosed, but there are questions concerning the magnitude and mechanisms of this effect in various dually diagnosed populations. Methods: Publications identified in a comprehensive review of the literature pertaining to 12-step programs and patients with addictions and co-occurring psychiatric disorders were reviewed for any content relevant to understanding the process of change involving dually diagnosed patients involved with 12-step programs. Results: Dually diagnosed individuals attend 12-step programs at rates comparable to the nondually diagnosed, although specific diagnoses may have some effect on attendance. The benefits of 12-step attendance do not appear to be markedly different for those with psychiatric disorders. Specialized 12-step programs could have benefits for the dually diagnosed over and above those of traditional 12-step programs. Existing data suggest that nonspecific change mechanisms (self-efficacy, social support) are similar to those found in the general AA literature. Conclusions: Based on existing data, the change mechanisms are broadly similar to those found in the general 12-step literature, but additional factors related to mental illness may also play a significant role. Further work is necessary to test the components of this model and to achieve a firm empirical foundation for understanding the processes of 12-step recovery in the dually diagnosed. © 2007 by the Research Society on Alcoholism.
