Person and Environment Predictors of Blood Alcohol Concentrations: A Multi-Level Study of College Parties

Hierarchical linear modeling analyses revealed significant variation at the party and individual levels. At the individual level, motivations to socialize were significantly associated with lower breath blood alcohol concentrations, while drinking games and providing the sample after 11:00 pm were associated with higher breath blood alcohol concentrations. At the party level, large parties were significantly associated with lower breath blood alcohol concentrations while reports of many intoxicated partygoers were associated with higher breath blood alcohol concentrations. Finally, we identified a significant gender by theme party interaction, indicating women had higher breath blood alcohol concentrations at theme parties relative to nontheme parties; however, breath blood alcohol concentrations for men were similar regardless of the type of party attended.
