[Concomitant treatment of psychosis and drug addiction.]

The high prevalence of addiction problems of people with psychosis and the lack of resources to respond to their complex reality has lead a multidisciplinary team at the Centre de santé mentale communautaire (CSMC) to establish a group allowing interventions on drug addiction and psychosis in a concomitant way. Following a brief presentation of problems and intervention models proposed in the literature, this article aims at summarizing the experience of the CSMC and their strategy in order to respond to the needs of these patients. Thus, this article presents the reasons for modifications made over the years, the relevance of the motivational approach with these patients who are often unmotivated in changing their behaviour regarding substance abuse and the strengths and limits of this approach. The objectives of the therapeutic group, the framework, content and clientele are then discussed. Finally the authors examine various perspectives.
