ESTRUCTURA FACTORIAL Y FIABILIDAD DEL DRINKING MOTIVES QUESTIONNAIRE REVISED SHORT FORM (DMQ-R SF) EN ADOLESCENTES MEXICANOS.

One of the most widely used and studied instruments worldwide to assess the reasons for consuming alcohol is the Drinking Motives Questionnaire (DMQ) based on the Cox & Klinger (1988) model, of which different versions have been made and have shown different factorial structures. However, in Mexico the psychometric properties of the DMQ and its versions have not been studied. Objetive. Due to the need for an instrument to assess the reasons for alcohol consumption, this study set out to adapt and study some psychometric properties of the DMQ-R and its different versions in the Mexican adolescent population. Method. The longest version of the questionnaire (28 items) was administered to 464 adolescents between 13 and 18 years old (M = 16.20; SD = 1.24), in this sample n=179 were female (55.1%). Results. Five different versions of the test were fitted. The only model that obtained an adequate fit was that of the short version of 12 questions, which also showed adequate internal consistency indexes (α = .88 y ω = .94). Conclusion. The short version of the DMQ-R-12 is an instrument that has shown adequate construct validity and reliability to evaluate the reasons for alcohol consumption in Mexican adolescents.
