Beliefs about drinking behavior predict drinking consequences.

Cognitions about drinking, such as positive expectancies and self-efficacy, have been found to profoundly influence drinking behavior. Although the relationship of self-efficacy and positive expectancies with drinking consumption has been established, the relationship of self-efficacy and alcohol expectancies with the number of reported drinking related consequences has not been examined. One hundred thirteen participants who met criteria for alcohol abuse or dependence were administered the Situational Confidence Questionnaire, the Alcohol Expectancies Questionnaire, the Drinker Inventory of Consequences-Recent, and the Losses of Significance Self-report Questionnaire-Revised. As predicted, lower self-efficacy and greater positive alcohol expectancies predicted greater recent drinking consequences beyond those accounted for by alcohol consumption alone. Greater numbers of positive alcohol expectancies also predicted greater numbers of recent important alcohol related losses. Correcting errant assumptions about alcohol expectancies and strategies designed to increase self-efficacy may reduce harmful drinking consequences even if a client is unwilling to reduce consumption.
