Abstract

The psychometric properties of the Modified Drinking Motives Questionnaire — Revised (Modified DMQ-R) [Blackwell, E., & Conrod, P. J. (2003). A five-dimensional measure of drinking motives. Unpublished manuscript, Department of Psychology, University of British Columbia], based on a five-factor model of drinking motives with separate coping-anxiety and coping-depression factors, were evaluated in undergraduates. In Study 1, confirmatory factor analyses supported the correlated five-factor model in two samples of undergraduate drinkers (N = 726 and N = 603). Furthermore, the five-factor model fit the data better than a four-factor model conceptually equivalent to that of Cooper [Cooper, M. L. (1994). Motivations for alcohol use among adolescents: Development and validation of a four-factor model. Psychological Assessment, 6, 117–128] (i.e., with coping-anxiety and coping-depression items constrained to a single factor). In Study 1, drinking motives were predictive of concurrent drinking frequency and typical number of alcoholic beverages per occasion, over and above demographics. In Study 2, the Modified DMQ-R scores showed good to excellent test–retest reliability in a sample of undergraduates who were relatively frequent drinkers (N = 169). Also, drinking motives prospectively predicted number of drinks consumed per week and alcohol-related problems, over and above demographics and initial alcohol use. Notably, coping-anxiety and coping-depression motives were distinctly related to alcohol consumption and alcohol problems.
