Abstract: This study examines whether self-perceived popularity, need for popularity, and peer pressure explain teenagers use of the mobile phone to make and distribute hurtful pictures and videos of peers and teachers. A large-scale quantitative survey study among 1787 Flemish high school pupils in 2010 revealed that, in the six months prior to the study, 25% of adolescents had made a picture/video of a peer who was being ridiculed, 8% of a peer who was being physically bullied, and 11% had distributed such a picture/video online. Thirteen percent had made a picture/video of a teacher being ridiculed, and 6% had distributed such content online. Self-perceived popularity, need for popularity, and perceived peer pressure positively predicted adolescents involvement in several of the above practices. The results suggest that greater investments need to be made to counter the social rewards that adolescents receive when engaging in these bullying practices.
