An essential component of healthy sexual exploration is the understanding of sexual consent. Unfortunately, sexual consent is not consistently taught in sex education programs developed for adolescents. Furthermore, although early adolescence is a critical developmental period for the formation of sexual identity, norms, attitudes, and relationships, this population is underrepresented in the sexual consent literature. To fill this important gap, this study examined the sexual consent beliefs, attitudes, and behaviors of 254 middle school students from a large, urban city in the province of Ontario. Correlates and predictors of sexual consent endorsement were tested via bivariate and multiple regression analyses. Greater perceived negative sanctions of dating violence and higher endorsement of gender stereotypes emerged as variables significantly related to and predictive of sexual consent attitudes, perceived behavioral control, and affirmative consent norms. Gender was also a significant correlate, as girls were more likely than boys to endorse affirmative sexual consent beliefs, attitudes, and behaviors. The findings highlight important group differences and provide guidance for the design and implementation of sexual education and prevention programs.
