The mood management intervention will result in higher levels of adaptive coping behavior, self-efficacy, social support, and perceived support from the counselor, and lower levels of negative affect, rumination, and perceived stress, than the health & wellness intervention and these variables will be related to abstinence. Thus, we will evaluate the effects of the intervention (health & wellness and mood management) on hypothesized treatment mechanisms, and assess the impact of those mechanisms on abstinence.
