Five outpatient treatment models for adolescent marijuana use: a description of the Cannabis Youth Treatment Interventions.

The five manual-guided treatment models tested in the Cannabis Youth Treatment study funded by the Center for Substance Abuse Treatment are described. The five models include (a) a 6-week intervention consisting of two sessions of individual motivational enhancement therapy plus three sessions of group cognitive behavioral therapy (MET/CBT5); (b) a 12-week intervention consisting of two sessions of motivational enhancement therapy plus 10 sessions of group cognitive behavioral therapy treatment (MET/CBT12); (c) a 12-week intervention consisting of MET/CBT12 plus the family support network (FSN), a multi-component intervention that includes parent education, family therapy and case management; (d) a 12-week intervention based on the adolescent community reinforcement approach (ACRA), an individual behavioral treatment approach designed to help adolescents and their parents reshape their environment and learn new skills; and (e) multi-dimensional family therapy (MDFT), a multi-faceted, developmentally and contextually oriented family-based model targeting individual, family and social systems. For each model, we describe the treatment background and/or its empirical support, its theoretical underpinnings, its goals and proposed treatment mechanism and the structure and content of each treatment. Procedures used for maintaining treatment fidelity and monitoring quality assurance are also described. These interventions represent the first readily available, manual-guided interventions to be evaluated in a large randomized field study for this population. Consequently, these manuals have the potential to advance treatment and research for adolescents with substance use disorders.
