Note. a Effects of X on M; b effects of M on Y; c total effect of X on Y; c’ direct effect of X on Yi controlling for M; Path a is consistent in all models; therefore, it presented only in model 1. Obsessive-compulsive symptoms is the predictor; Enhancement, Conformity, Expansion, Coping, and Social are the mediator variables; Risky cannabis use per the Alcohol, Cannabis use problems, and Cannabis Quantity is the outcome variable. LLCI lower bound of a 95% confidence interval; ULCI upper bound; → effects. The indirect effect (a*b) is the product of path a and path b. Bolded values are statistically significant. Problematic alcohol use and smoking status were covariates.
