Predictors of change in binge drinking over a 3-month period

Abstract Self-efficacy and positive and negative alcohol expectancies have been associated with drinking reduction for some groups, but the relationship of these constructs with changes in high-risk binge drinking behavior among young adults over time is poorly understood. Seventy-six young adults between the ages of 18–32 were recruited to examine this question. Lower self-efficacy and greater positive alcohol expectancies predicted greater numbers of follow-up binge drinking episodes, and greater positive alcohol expectancies predicted greater follow-up alcohol consumption. Young adults with lower self-efficacy, and greater numbers of positive alcohol expectancies may be at risk for experiencing a worsening binge pattern over time.
