Validation of the Drinking Motives Questionnaire (DMQ) in older adults

Drinking motives have been established as an important construct in the prediction of alcohol use and drinking problems among younger adults, but there is little understanding about the drinking motivations of older adults. Although emerging evidence shows the importance of studying older adults' own reasoning for their alcohol consumption, measures that have been used to assess such reasons lack psychometric assessment. This study aims to validate the three-dimensional structure of the Drinking Motives Questionnaire (DMQ) in older adults and to investigate the relationships between drinking motives and alcohol use. A sample of community dwelling older adults (N=370) completed self-report measures assessing drinking behavior and motives for drinking. Using confirmatory factor analysis, the results supported a three-factor model of drinking motives. Multi-group analysis of invariance showed support for configural and metric invariance, and partial support was met for scalar invariance. Social motivations for drinking were the most frequently endorsed, followed by enhancement, and coping motives. Males reported more frequent drinking for each of the three motives. Social motives were consistently related to drinking behaviors and coping had a direct relationship to drinking problems. Overall, the study shows that the DMQ has promise as a measure for use with older adults.
