In search of the seven dwarves: Issues of measurement and meaning in alcohol expectancy research.

Discusses substantive issues in predicting drinking patterns from expectancies, as well as issues of content and measurement of the scales developed to measure these expectancies. In recent years, much research has suggested that alcohol expectancies--or the beliefs that individuals hold about the effects of alcohol on their behavior, moods, and emotions--are an important factor in motivating drinking behavior. Although measures of these expectancies have consistently been shown to be correlated with measures of alcohol use, conceptual and methodological problems remain to be addressed. In order to progress in understanding this potentially important psychosocial factor in abusive and nonabusive drinking, alcohol expectancy research, which has been atheoretical in nature, should attend to potential contributions from other areas of research in psychology.
