If You’re High Status and You Know It - Teasing Apart the Within- and Between-Person Effects of Peer- and Self-Reported Status in the Drinking Group on Alcohol-Related Outcomes

We conducted a longitudinal study on university students’ drinking groups, with a focus on peer-reported and self-reported status as predictors of students’ drinking-related behavior. We first examined average between-persons differences in group members’ typical status as a predictor of systematic changes in their drinking-related behavior over time. We then examined within-person effects, or how students’ drinking-related behavior changes as a function of time-specific changes in their typical status.
