NATIVIDADE, Jean Carlos; AGUIRRE, Alba Recalde; BIZARRO, Lisiane and HUTZ, Claudio Simon. Personality factors as predictors of alcohol consumption by university students. Cad. Saúde Pública [online]. 2012, vol.28, n.6, pp.1091-1100. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2012000600008.
This study aimed to verify differences in personality factors between abstainers and drinkers and between individuals with higher versus lower levels of alcohol consumption in the previous three months, and to test the predictive power of factors for any lifetime alcohol consumption and for at least monthly alcohol consumption. A total of 169 university students participated, of whom 66.7% were women, with a mean age of 21.2 years. Lifetime alcohol consumption was 90.1%; 42.3% had consumed at least twice in the previous three months; and 57.7% consumed alcohol at least monthly. Participants with less frequent consumption in the previous three months showed higher mean scores for personality factors involving socialization and achievement, while those that consumed more frequently scored higher on extroversion. A predictive model showed that increments in extroversion contributed to increased odds of drinking alcohol, while increments in achievement decreased the odds of drinking. Personality characteristics were able to distinguish between different groups of drinkers and predict the frequency of alcohol consumption.
