Alcohol expectancies and motives in a substance abusing male treatment sample

Abstract

Although prior research has demonstrated the utility of both alcohol expectancies and drinking motives in the prediction of alcohol use and problems, the specific relationship between these domains has not been examined in a clinical sample. One-hundred, forty-seven veterans on an inpatient substance abuse unit completed questionnaires measuring alcohol expectancies and alcohol motives and provided information on their alcohol consumption and related problems. Covariance structure modeling was used to test four theoretically competing models. Findings indicated that: (1) motives mediate the effects of expectancies on use and problems and expectancies do not exert an independent influence on consumption and alcohol problems and (2) contrary to past findings, alcohol use only partially mediates the relationship between enhancement motives and alcohol problems.
