Perceptions of Community Norms and Youths' Reactive and Proactive Dating and Sexual Violence Bystander Action.

There is enthusiasm for programs that promote bystander intervention to prevent dating and sexual violence (DSV). However, more information about what facilitates or inhibits bystander behavior in DSV situations is needed. The present cross-sectional survey study investigated whether youth perceptions of adults' behavior and community norms were associated with how frequently youth took action and intervened in DSV situations or to prevent DSV. Specifically, study hypotheses were that youths' perceptions of community-level variables, such as adults' willingness to help victims of DSV or prevent DSV, perceptions of community collective efficacy, and perceptions of community descriptive and injunctive norms disapproving of DSV and supporting DSV prevention, would be associated with how frequently youths took reactive and proactive bystander action. Participants were 2172 students from four high schools in one New England state. ANOVA analyses found that descriptive norms were associated with all actionist behaviors, and perceptions of community cohesion were also consistently associated with them. Injunctive norms were associated, but less consistently, with actionist behaviors. Findings suggest that DSV-related social norms, and descriptive norms and community cohesion in particular, might be relevant to youth DSV bystander behavior.
