Psychometric Properties of the Alcohol Expectancy Questionnaire (AEQ-A) in psychology students from Mar del Plata, Argentina

Abstract

The aim of this article was to analyze the psychometric properties of an adapted version of the Alcohol Expectancy Questionnaire Adolescents (AEQ-A) in university students from Mar del Plata city, Argentina. Expectancies about the effects of alcohol refer to the beliefs that people hold about the consequences of alcohol consumption on behavior. Expectancies have been related to drinking initiation and maintenance, and to habitual drinking patterns. Although several questionnaires have been developed to measure expectancies, the AEQ-A has been one of the most frequently used. Studies in different cultural contexts have shown that, given expectancies’ cultural variability, the questionnaire must be adapted to each particular context. A version of the AEQ-A previously validated in Mar del Plata, Argentina, was used, consisting of 40 items measured on a (true / false) dichotomous scale. The sample consisted of 1076 psychology students from the National University of Mar del Plata, Argentina. Exploratoryand confirmatory factor analyzes were performed. The factorial analysis resulted in six factors containing 37 items. Internal consistency of each subscale was adequate. Concurrent validity was satisfactory inasmuch as scores on the subscales about beliefs associated with positive effects of consumption in social situations relate to heavy episodic drinking. Instruments like this one to evaluate expectancies, will allow the study of psychosocial factors associated with consumption and provide useful information to develop prevention strategies.
