  1. *p < .05. **p < .001. ICC = intraclass correlation coefficient. CI = confidence interval. Notes: Final models were adjusted for student gender, classroom mean gender, student sexual experience, classroom mean sexual experience, and pretest score. The adjusted standardized mean difference represents the regression estimate divided by the within-classroom standard deviation from the final model for each outcome; the confidence interval for the adjusted standardized mean difference represents the regression estimate’s confidence interval divided by the within-classroom standard deviation from the final model for each outcome.
