Abstract
Traditional bullying perpetration explicates the importance of a power differential between the bully and the victim—predominantly physical and/or social status. The application of power from traditional to cyberbullying is unclear. The current research utilized a longitudinal study to examine the relationships between four different derivations of power—belief in the irrelevance of muscularity for online bullying (BIMOB), social capital, harmful computer skills, and popularity motivation—and cyberbullying attitudes and perpetration. Participants (185 US emerging adults) completed self-report assessments of the aforementioned power constructs, cyberbullying attitudes, and cyberbullying behavior twice—6 months apart. Results showed only Wave 1 BIMOB predicted cyberbullying attitudes to yield subsequent cyberbullying perpetration.
