Factors influencing the temporal relationship between alcohol consumption and experiences with aggression among college women

The authors assessed temporal relationships among alcohol use, aggression, and mood using daily data from 179 college women. Participants called an interactive voice response system over an 8-week period. The odds of experiencing verbal, sexual, and physical aggression (odd ratios = 2.25, 19.44, and 11.84, respectively) were significantly higher on heavy drinking days (M = 7.46 drinks) compared to non-drinking days. Both a history of victimization and greater psychological symptom severity influenced the odds of involvement in verbal aggression. The odds of alcohol consumption were 3 times higher during the 24 hr following verbal aggression compared with days in which verbal aggression did not occur. On the day immediately following involvement in either verbal or physical aggression, positive mood decreased and negative mood increased. During the week (2-7 days) following sexual aggression, women's positive mood was decreased. These findings reinforce the need for interventions aimed at reducing heavy episodic drinking on college campuses.
