Prediction of treatment outcome in a clinical sample of problem drinkers: self-efficacy, alcohol expectancies, and readiness to change.
Cognitive processes related to client motivation are important mediators of alcoholism treatment outcome. The present study aimed to expand previous research on client motivation and treatment outcome by establishing the predictive utility of self-efficacy, alcohol expectancies, and readiness to change in a sample of alcohol-dependent inpatients (N = 83). Treatment outcome was assessed three months following discharge. According to self-reported alcohol use, 22 clients were classified as abstainers and 41 clients as relapsers. Twenty participants were lost to follow-up. Readiness to change and anticipated reinforcement from alcohol predicted abstinence at follow-up. Client motivation was unrelated to both frequency and quantity of alcohol use. In accordance with social learning theory, self-efficacy was inversely correlated with alcohol expectancies. The results of the present study suggest that once abstinence has been violated factors other than pretreatment motivation determine drinking behavior.
