Cyberbullying is a relatively new form of interpersonal aggression that has become a widespread topic of public concern. Although cyberbullying is not as prevalent as traditional bullying, it is a problem that has become commonplace in many young people’s lives. In general, approximately one in five children and adolescents have been involved in some form of cyberbullying. Males are more likely to engage in cyberbullying perpetration, while females are at higher risk for victimisation. Other risk factors related to cyberbullying involvement include violent family context, unsupportive parenting and school climate, involvement in traditional bullying, low self-esteem, low self-control, high socioeconomic status, and frequent technology use. Various negative consequences impacting physical, emotional, social, and cognitive development have been associated with cyberbullying. Since many researchers predict that cyberbullying rates will increase in the future, continued prevention and intervention efforts are warranted.
