Brief Summary
The goal of this research is to improve treatment outcome for marijuana-dependent individuals. The current study builds on the findings of our prior NIDA-funded marijuana treatment study in which improved client outcomes were associated with greater treatment attendance, greater client self-efficacy, and greater use of coping skills. We will use a contingency management paradigm to provide tangible reinforcement for completing homework assignments that are designed to enhance coping skills. It is anticipated that this will result in greater homework compliance, leading to greater self-efficacy regarding one's ability to cope with high-risk situations. Improved self-efficacy will enhance the likelihood of employing coping skills in high-risk situations, thereby increasing the probability of achieving and maintaining abstinence.
