Students experience many forms of victimization at school, yet few studies address more than one form of victimization. In this study, we explored the incidence of multiple forms of peer victimization, including direct verbal and physical, relational, and sexual harassment victimization among urban middle school students. We examined the overlap and gender differences among victimization experiences. Further, social cognitive theory was used to better understand how victimization experiences influence beliefs about the acceptability of aggression. Youth in 6th through 8th grades (N=111) completed self-report measures assessing peer victimization experiences and normative beliefs about aggression. Results revealed overlap between victimization experiences, suggesting that students commonly experience multiple forms of victimization by peers. Males who were sexually harassed held the strongest beliefs supporting aggression in situations without provocation. Our findings suggest that direct physical/verbal, relational, and sexual harassment victimization are inter-related experiences among youth, and these experiences differ by sex. (Contains 4 tables.)
