Note. IR = Incapacitated Rape. Percentage or mean (standard deviation) are shown. P values reflect the significance of chi-square test of independence for Fisher’s exact test for categorical variables (i.e., past-year IR at follow-up) and Welch’s t-test for continuous variables (i.e., all other variables). Bolded values are significantly different at p < .05. One participant in Study 1 was missing data on blackout frequency. A different participant in Study 1 was missing data on two of four items within the situational control motives scale; thus, a mean value was not computed for this participant. Two participants in Study 2 were missing past-year IR data at baseline and excluded from examination of bivariate associations.
