“…Investigating college students' unique reasons for drinking is useful for informing future interventions focused on promoting responsible drinking behavior and harm reduction. Drinking motives predict drinking behaviors and consequences and are essential for understanding alcohol use (Cooper, 1994;Cox, 1990;Cox & Klinger, 1988). One existing measure, the Drinking Motives Questionnaire (DMQ) (Cooper, 1994), has been widely used to examine drinking motives as they relate to drinking contexts, behaviors, and consequences (Cooper, 1994;Gorka et al, 2017;Kuntsche et al, 2005;Kuntsche & Cooper, 2010;Kuntsche & Müller, 2012;Piasecki et al, 2014).…”

Objective: Self-Determination Theory (SDT) examines human motivation in multiple domains, facilitating comparison of motives across health behaviors. However, no existing measure assesses SDT-informed motives for drinking, which is necessary for understanding how SDT-based motives influence drinking and how drinking motives overlap with other health behavior motives. This study tested and cross-validated the structural and external validity of the SDT-informed Comprehensive Relative Autonomy Index for Drinking (CRAI-Drinking). Method: 630 adults (Mage=21.5, 55% female, 88% undergraduates) rated drinking motives on the CRAI-Drinking and Drinking Motives Questionnaire (DMQ), typical alcohol consumption, and negative and positive drinking consequences. Results: In Sample 1 (n=274), CRAI-Drinking item and subscale order aligned with SDT’s autonomy continuum. A five factor, 19-item model with factors for intrinsic, identified, positive introjected, external, and amotivation regulations (Cronbach’s α: 0.68-0.85) showed acceptable model fit in Sample 1 and in cross-validation Sample 2 (n=356). In the combined sample (n=630), CRAI-Drinking scores demonstrated convergent (r=0.45 to 0.76) and divergent (r=0.01 to 0.41) validity with the DMQ. Poisson regressions indicated that intrinsic (IRR=1.13) and identified (IRR=1.11) regulations were significantly associated with drinking frequency, identified (IRR=0.94) and positive introjected (IRR=1.08) regulations were significantly associated with drinking intensity, and amotivation (IRR=1.16) and intrinsic regulation (IRR=1.09) were associated with negative or positive consequences, respectively, after controlling for other CRAI-Drinking and DMQ factors, sex, and drinking intensity. Conclusions: The CRAI-Drinking provides unique information regarding associations between drinking motives, behaviors, and consequences, providing the first SDT-based measure of drinking motives enabling comparison of drinking motives with other health behavior motives.
