Psychometric Properties of Drinking Motives Questionnaire-Revised (DMQ-R) in Slovak Adolescents
The objective of the study was to verify the psychometric properties of DMQ-R questionnaire in Slovak adolescent population. DMQ-R is targeted at measuring four motives for alcohol consumption. Using the sample of 533 high school students from Slovakia, its content, construct and criterial validity as well as the level of reliability were examined. The given psychometric properties were verified via factor analysis, internal consistency coefficient, correlations with constructs of situation motivation factors and problems caused by alcohol consumption. For data collection, the creation of Slovak version of DMQ-R was needed; the questionnaire battery was further supplemented by the Questionnaire on Situation motivational Alcohol Behaviour Factors (SMF) and the Rutgers alcohol problem index (RAPI). The results showed the DMQ-R (in Slovak version) to be sufficiently valid and reliable in Slovak population.
