Note. OR = odds ratio; CI = confidence interval; B = regression estimate; Freq. = frequency of; Attend. = attendance; GPA = grade point average. Two-part modeling looked at the probability of experiencing any oral sex hookup and the number of oral sex hookups given at least one occurred. All predictors were entered into the regressions; regression weights for highly non-significant predictors (T > 1) were fixed at zero to stabilize estimates. All remaining coefficients are reported. Significant predictors appear in boldface type.
