Assessing the Dependability of Drinking Motives via Generalizability Theory.
This study assessed the score reliability of the Drinking Motives Questionnaire-Revised (DMQ-R) via generalizability theory. Participants (n= 367 college students) completed the DMQ-R at three time points. Across subscale scores, persons, persons × occasions, and persons × items interactions accounted for meaningful variance. Findings illustrate advantages of generalizability theory-based techniques.
