This study examined to what extent bullying behavior of popular adolescents is responsible for whether bullying is more or less likely to be accepted or rejected by peers (popularity-norm effect) rather than the behavior of all peers (class norm). Specifically, the mean level of bullying by the whole class (class norm) was split into behavior of popular adolescents (popularity-norm) and behavior of non-popular adolescents (non-popularitynorm), and examined in its interaction with individual bullying on peer acceptance and peer rejection. The data stem from a peer-nominations subsample of TRAILS, a large population-based sample of adolescent boys and girls (N=3312). The findings of multilevel regression analyses demonstrated that the negative impact of individual bullying on peer acceptance and the positive impact on peer rejection were particularly weakened by bullying by popular adolescents. These results place the class-norm effects found in previous person-group dissimilarity studies in a different light, suggesting that particularly bullying by popular adolescents is related to the social status attached to bullying.Keywords Bullying .

RejectionResearch on peer relations has demonstrated that acceptance or rejection of behaviors varies in accordance with the behavioral norm in the peer group or classroom (e.g., Boivin et al. 1995;Chang 2004;DeRosier et al. 1994;Jackson et al. 2006;Sentse et al. 2007;Stormshak et al. 1999). In most of these studies, researchers drew on the person-group dissimilarity model of Wright et al. (1986). This model postulates that negative social behaviors like aggression are more likely to lead to negative peer evaluations when these behaviors are not normative (infrequent) in the peer context. That is, children will be rejected when their behavior is dissimilar to that in their peer group context (they deviate from the group norm), but not if they display behavior similar to that of their peers.These studies have, however, neglected differences in influence reflected by adolescents' reputation-based status in the peer group. Adolescents with a high-status position among peers have more power and the ability to exert influence upon their peers directly or indirectly Adler 1995, 1998; DeBruyn and Cillessen 2006;LaFontana and Cillessen 2002;Lease et al. 2002;Parkhurst and Hopmeyer 1998). In view of their influential position among peers, it seems reasonable to suggest that involvement of popular adolescents in certain behaviors might affect the class norm and, consequently, the acceptance and rejection of behavior.In the present study, we examined the interplay between the class norm and status. The role of status was incorporated in the original person-group dissimilarity model to explain the diffuse relation of negative behavior (here: bullying) with peer acceptance and peer rejection. We would like to investigate whether it is not the class norm as expressed by the mean level of behavior of all peers but rather the mean ...
