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.
The purpose of the present study was to examine the initial psychometric properties of the Gambling Problems Scale (GPS), developed for the college student population. Participants were college ...students recruited for an ongoing larger clinical trial from a Midwestern university who reported gambling in the past 60 days and who were experiencing gambling-related problems, scoring +3 on the South Oaks Gambling Screen or +1 on the Brief Biopsychosocial Gambling Index (N = 334). Factor analyses and reliability analyses were conducted to examine the validity of score interpretation and the reliability of scores for the measure. Results suggested a 16-item unidimensional measure provided the best parsimony and theoretical fit. Examination of concurrent and incremental validity of scores provided additional support for the psychometric properties of the GPS. The GPS may be a useful tool for researchers and clinicians interested in examining gambling-related problems among college students and other young adults.
Drinking motives have been associated with alcohol use and alcohol-related problems among young adult drinkers (Kuntsche et al., 2005). We included a sample of 360 college students and fit latent ...profile models at each time point using 12-items from the Drinking Motives Questionnaire-Revised (DMQ-R: Cooper, 1994), which were determined the most discriminating items via Item Response Theory. Patterns of motives were identified using Latent Transition Analysis and included alcohol quantity and problems as covariates with quantity as a moderator to examine transitions. A 3-class model provided the best fit and parsimony: a) High Motive, endorsed items highly (baseline: 11%, 6-month: 10%, 12-month: 14%), b) Positive Reinforcement Motive , endorsed positive affect/social interaction items (49%, 53%, 49%), c) Low Motive, had low motive endorsement (39%, 37%, 38%). These findings suggested High Motive and Positive Reinforcement Motive classes drank more (High Motive, baseline: OR = 1.05, p <0.05, 6-month OR = 1.07, p < 0.05; Positive Reinforcement Motive, baseline: OR = 1.08, p < 0.001, 6-month: OR = 1.04, p < 0.05) and experienced more problems (High Motive baseline: OR = 1.14, p < 0.00, 12-month: OR = 1.06, p < 0.001; Positive Reinforcement Motive, baseline: OR = 1.12, p < 0.001). Transitioning between 6- and 12-month follow-up was less likely for higher levels of alcohol use (+1 SD: ORs = 0.32-0.44, ps < .05). This study provided evidence for the stability of drinking motives and targeting the positive reinforcing beliefs of alcohol, as these individuals are at higher risk for experiencing problems.
