Due to the impersonal and anonymous nature of cyberspace, past work underscored the pivotal role of social influence processes in cyberbullying among adolescents. However, there was also evidence revealing the weak influences that some referent groups yield on youth. The current study argues that the strength of normative influences on cyberbullying depends on the properties of the referent groups. In the school context, we examined whether class entitativity-the extent to which a class is a unified and coherent group, rather than a mere aggregation of students-moderated the relationship between class norms and cyberbullying. A total of 474 adolescent students responded to measures of descriptive and injunctive class norms about cyberbullying, perceived class entitativity, and cyberbullying. The results indicated that pro-cyberbullying descriptive and injunctive class norms were positively correlated with cyber aggression. Most importantly, higher levels of pro-cyberbullying class norms predicted increases in cyber aggression when students perceived their classes as highly entitative. In contrast, this effect was not significant when students perceived their classes having low entitativity. These findings promote an understanding of how peer norms work and provide an alternative strategy for interventions into cyber aggression in schools.
