Why do adults drink alcohol? Development and validation of a Drinking Motives Questionnaire for adults.

The Drinking Motives Questionnaire-Revised (DMQ-R; Cooper, 1994) is frequently used to assess adult drinking motives despite being designed for younger drinkers. This study aimed to develop and validate a Drinking Motives Questionnaire for Adults (DMQ-A). A convenience sample of 1,617 adults (25-65-year-olds; The DMQ-A was found to have social, coping, confidence, taste, and enhancement dimensions. The DMQ-R conformity dimension was replaced by one of drinking for confidence and a novel drinking for taste dimension was identified. The second half of the split sample was used to demonstrate the DMQ-A's adequate model fit (CFI = 0.93), good internal consistency (α = .81-.90) and 6-month test-retest reliability ( The DMQ-A is a promising tool for future research or clinical application involving adult alcohol use.
