Beliefs about the consequences of using alcohol, alcohol expectancies, are powerful predictors of underage drinking. The Alcohol Expectancies Questionnaire-Adolescent form (AEQ-A) has been widely used to measure expectancies in youth. Despite its broad use, the factor structure of the AEQ-A has not been firmly established. It is also not known whether it assesses similar constructs (i.e., measurement invariance) between boys and girls. This article reports on a confirmatory factor analysis (CFA) of a shortened version of the AEQ-A with 310 youth, ages 10-16, to determine whether a two factor, positive and negative expectancy structure held for this sample and to test measurement invariance across gender. The results support evidence of a 2-factor, positive and negative structure for the abbreviated version of the AEQ-A and show that it assesses equivalent alcohol expectancy constructs among males and females. These findings have important implications for cognitive based approaches to alcohol prevention. © Springer Science+Business Media, LLC 2006.
