Abstract |
Hypotheses regarding the relationships between self-efficacy for avoiding marijuana use and theoretically related measures were examined in a sample of 161 men and 51 women who sought treatment aimed at marijuana cessation. Theoretically proposed sources of efficacy judgments showed stronger univariate and multivariate relationships with efficacy for avoiding marijuana use after treatment than before treatment. The cognitive-behavioral relapse prevention treatment resulted in marginally greater self-efficacy, compared with a nonbehavioral treatment, but the link between coping skill training and efficacy was ambiguous. Efficacy contributed incrementally to the prediction of posttreatment marijuana use beyond efficacy source variables, but it did not completely mediate the effects of those sources of efficacy judgments. Predictive validity was stronger for frequency of posttreatment marijuana use than for abstinence status. The need for better assessment of the efficacy construct and potential revisions in efficacy theory as applied to substance use are discussed.
