Abstract
BACKGROUND: Motives for use have been identified as important predictors of substance use and related problems; however, little is known about how motives for use change following an intervention and how this change may impact future substance use behaviors. The present study sought to describe change in motives following an intervention for marijuana-dependent adults. Furthermore, investigators examined change in motives as a predictor of treatment outcome. METHOD: The study randomized 74 adults to one of two conditions: both of which received 9-sessions base treatment ofcognitive behavioral therapy and motivational enhancement therapy and had access to additional sessions of cognitive behavioral treatment on an as-needed basis. The experimental condition received two additional "check-ups" during the course of follow-up. RESULTS: Significant decreases in reported frequency of motives used were observed following treatment. Changes in Expansion and Coping were associated with differential treatment outcomes. Decreases in Expansion were associated with poorer treatment outcome, while decreases in Coping were associated with better treatment outcome. CONCLUSIONS: The relationship between expansion motives and outcomes was paradoxical. Although there were some inconsistencies in the findings, the results regarding the coping motive were consistent with hypotheses and may have important implications for treatment.
