Perceived and Actual Norms, and Norm Misperceptions in Explaining Participant Roles in Bullying.

Bullying norms have been shown to affect adolescents' decisions on different behaviors in bullying situations, but little is known about the differential contribution of perceived and actual bullying norms as well as their agreement. The present study investigated the effects of perceived and actual norms, along with norm misperceptions in participant roles in bullying. A sample of 890 students (337 fourth-, 223 fifth-, and 320 sixth-graders; Female 48%; M = 11.98, SD = 0.82) from 34 classrooms in South Korean elementary schools was assessed at two time points: at the beginning (Wave 1) and at the end of the semester (Wave 2). Multilevel modeling results indicated that empathy as well as perceived and actual anti-bullying norms had unique effects on different participant roles in bullying. The agreement between perceived and actual norms also varied across classes, and bullying, victimization, and bystanding were found to be higher in classes where individuals misperceived the actual anti-bullying norms. Adolescents were more likely to defend in response to their empathy in classes with higher anti-bullying norms, while they were less likely to bystand in response to their empathy in classes where individuals accurately perceived the actual anti-bullying norms. These findings underscore that intervention programs can focus on correcting adolescents' erroneous perceptions and convictions about peers' anti-bullying attitudes to alleviate bullying and its negative consequences.
