The Indirect Effects of Self-Efficacy on Cannabis Use via Cannabis Protective Strategies: A Preliminary Study

Abstract

Cannabis use has more than doubled in the past decade and nearly three of 10 users develop a cannabis use disorder. The increase in users, combined with the ongoing changes in the medical, legal and social status of cannabis, has contributed to interest in the antecedents of cannabis use. In the current preliminary study, we gathered information from a community sample (N = 54) of regular cannabis using young adults. Assessments included perceived self-efficacy for reducing intake or abstaining (SE-R/A), use of cannabis protective strategies (CPS), and average quantity of cannabis use per day. We systematically explored which specific CPS were most strongly associated with self-efficacy and cannabis use. Three clinically relevant subgroups of CPS emerged from this analysis: strategies strongly associated with only self-efficacy, only cannabis use, and both variables. We hypothesized that self-efficacy would be associated with less cannabis use via use of CPS. Among specific CPS examined, "Use a little and then wait to see how you feel before using more" had the strongest association with self-efficacy while "Avoid methods of using cannabis that can make you more intoxicated than you would like" had the strongest negative association with cannabis use. We observed a significant indirect relationship from self-efficacy to cannabis use through use of CPS. Our findings suggest that use of CPS is a potential mechanism by which cannabis users reduce use, and a more proximal antecedent of cannabis use than personal confidence in one's ability to stop using. These preliminary findings highlight the value of studying individual strategies. They also may have implications for promoting use of cannabis protective strategies when treating those with cannabis use problems.
