This study examines the phenomenon of cyberbullying on Facebook and how it is related to school bullying among secondary school students in Singapore, aged 13–17. We also focus on generic use of Facebook and risky Facebook behaviors as the predictors of cyberbullying and victimization on Facebook. 1676 secondary students, from two secondary schools, participated in a pen and paper survey. The findings show that the intensity of Facebook use and engagement in risky Facebook behaviors were related to Facebook victimization and Facebook bullying, respectively. Moderately strong positive relationships between school bullying and Facebook bullying, as well as between school victimization and Facebook victimization, were also uncovered
