Note: Reference category for both IPV perpetration groups at T2 is No IPV (n = 226). OR = odds ratio; CI = confidence interval; IPV = intimate partner violence; T0 = baseline (senior year in high school); T1 = first fall semester in college; T2 = first spring semester in college; HED = heavy episodic drinking. N is reduced due to listwise deletion of cases missing data on one or more variables.
Dummy variable; reference group is No IPV at T1.
Dummy variable coded 1 for yes, 0 for no.
