Confirmatory factor analysis of the Brazilian version of the Drinking Motives Questionnaire-Revised (DMQ-R)

The main objective of this study was to evaluate the factor structure of the Brazilian version of the Drinking Motives Questionnaire-Revised (DMQ-R; Cooper, 1994) in a sample of 584 university students. A secondary goal was to investigate the relationships between motives and measures of alcohol use and drinking problems. The DMQ-R assesses four motive dimensions: social, enhancement, coping, and conformity. Confirmatory factor analysis supported a revised four-factor model identical to the original, with the exception of one item that did not load on its intended factor. Relative to coping and conformity motives, enhancement and social motives were strongly related to both alcohol use and drinking problems. Overall results indicate that the factor structure of the Brazilian DMQ-R parallels that observed in North America and Europe using the original English language DMQ-R, despite a distinct pattern of relationships with alcohol use and drinking problems.

► DMQ-R is a popular psychometric measure of drinking motivations. ► Instrument was originally represented by a four-factor structure. ► This is the first study regarding DMQ-R structure with a Latin American sample. ► Analyses supported a four-factor structure for the Brazilian version of the DMQ-R.
