Drinking motives are vital in identifying risk factors and better understanding alcohol-related outcomes. However, context-specific motivations could provide greater motivational perspective on high-risk context-specific alcohol use behaviors such as prepartying (consuming alcohol prior to attending one's intended destination) than general alcohol motivations.
In the current study, students’ open-ended responses to reasons for prepartying were collected from a large diverse sample (n = 2497), and the most commonly offered reasons were used to create a prepartying motivations inventory (PMI) that was then administered to a different sample (n = 1085).
A split-half validation procedure was used for the purpose of evaluating the PMI's factor structure. Exploratory and confirmatory factor analyses yielded a final 12-item measure consisting of four distinct, but inter-related, factors: Interpersonal Enhancement, Situational Control, Intimate Pursuit, and Barriers to Consumption. Internal consistency reliability, discriminant validity, and criterion-related validity were empirically demonstrated.
Results support the notion that individuals preparty for a variety of reasons that are distinct from general motives. Researchers are encouraged to use the PMI in future research with young adults to provide further understanding of prepartying behavior and its psychosocial
correlates.
