Aims:
This paper had three aims: (1) to validate a Spanish adaptation of the Modified Drinking Motives Questionnaire-Revised (M DMQ-R), (2) to explore the relationship of each drinking motive with different patterns of alcohol use, and (3) to compare the drinking motives of moderate drinkers, heavy drinkers, and alcohol abusing/dependent individuals.
Methods:
Two studies were carried out. In Study 1, a sample of 488 participants completed the M DMQ-R and a self-report scale of alcohol consumption in order to study the factor structure and different indices of reliability and validity of the Spanish M DMQ-R. In Study 2, we compared the drinking motives of moderate and heavy drinkers from Study 1 and an additional sample of 59 clinical drinkers.
Results:
The M DMQ-R demonstrated sound reliability and validity indices. Coping-with-anxiety, social, and enhancement motives predicted higher alcohol use on weekends, but only coping-with-anxiety and social motives were related to consumption on weekdays. Furthermore, moderate drinkers had the lowest scores for all motives, whereas alcohol-dependent participants obtained the highest scores for negative reinforcement drinking motives.
Conclusion:
The Spanish M DMQ-R is a reliable and valid measure of drinking motives and has potential for assisting with treatment planning for problem drinkers.
