The research is about the prevalence of traditional and cyber bullying among Chinese middle school students, and we conducted the survey in some middle schools in Zhejiang, Chongqing and Henan provinces. We have three aims: 1. The prevalence of traditional and cyber bullying; 2. The association between traditional and cyber bullying; 3. Whether the occurrence of bullying is related to health status. The research serves for preventing violent related behaviors and providing suggestions for policies, which contributes to the psychosomatic well-being of teenagers.
