OBJECTIVE: To assess the relationship between alcohol use expectancies, drinking patterns, and alcohol-related problems, among college students in Mexico City. MATERIAL AND METHODS: This cross-sectional study was conducted in October 1998. Study subjects were 678 male and female college students aged between 17 and 25 years, from private and public schools. Alcohol expectancies were measured through the self-reported "Alcohol Expectancy Questionnaire" (AEQ), adapted for this population, with a high overall internal reliability coefficient (alpha=0.93). RESULTS: Thirty-one per cent of study subjects, mainly males, reported heavy drinking (5 drinks or more per drinking occasion in the previous year), while 17% were non-consumers. Relationships for each of the AEQ scales, drinking patterns, and alcohol-related problems, were analyzed through a structural equations model. Analysis of variance showed a statistically significant association between six AEQ subscales -alcohol as a facilitator of a group interaction, verbal expression, disinhibition, sexual enhancement, reduction of psychological tension and arousal agression- (F=5.23, df=1, p<0.05). CONCLUSIONS: Study findings from other countries show that effects attributed to alcohol, in anticipation of the drinking episode (expectancies), are closely related to alcohol intake. Our results showed that heavy drinkers had higher scores in six AEQ subscales, particularly those who reported having alcohol-related problems in the previous year. Alcohol expectancies related to higher alcohol intake were: facilitation of social interaction, decreasing psychological tension, and increasing arousal/aggression.
