Comparison of the Original and Short Form Drinking Motives Questionnaire-Revised With High School and Underage College Student Drinkers.

Cooper developed and provided initial support for the Drinking Motives Questionnaire-Revised (DMQ-R). More recently, Kuntsche and Kuntsche introduced the briefer DMQ-R SF. Psychometric properties of the DMQ-R and the DMQ-R SF were examined in samples of high school (n = 131) and underage college student drinkers (n = 189). The original and short-form versions of the DMQ-R were similar with regard to composite score validity, concurrent validity, and internal consistency. Only the Enhancement Motives subscale showed slight decrements in reliability and validity for the short form. Confirmatory factor analysis showed that the DMQ-R SF was associated with slightly better goodness-of-fit and invariant factor loadings between the high school and college student samples. Despite its briefer form and reduced task demands for participants, the DMQ-R SF appears to provide nearly equivalent, and in some instances slightly improved, measurement of drinking motives in underage drinkers as does the original DMQ-R.
