The rapid growth of electronic and computer-based communication and information sharing during the past decade has dramatically changed social interactions, especially among teenagers. Cyberbullying has emerged as a new form of bullying and harassment, and it has been shown to possess different ramifications from traditional school-yard bullying. This problem has emerged in nations worldwide. Cyber victims have reported various emotional and behavioral symptoms, along with school-related problems. This paper reviews international cross-sectional studies relating to the definition, prevalence, age, and gender differences inherent in cyberbullying. Psychosocial and risk factors associated with cyberbullying are also addressed. Prevention and intervention strategies for school officials and parents are suggested. Healthcare providers, policy makers, and families must be ever-mindful of the grave dangers cyberbullying poses to youths. Longitudinal studies are warranted to assess the psychological risk factors of cyberbullying.
