Abstract: A modified version of Olweus Bullying/Victimization Questionnaire was employed in a sample of 9205 primary and junior middle school children from both urban and rural areas, in order to evaluate the prevalence and explore the major characteristics of school bullying. The results indicated that serious bullying problems existed in primary and junior middle schools, with nearly one out of five (19%)of the children investigated getting involved in bullying problems. The ratios of victims and bullies decreased with the children's age, but that of the bullies kept relatively stable across the junior middle school years. Direct verbal bullying was the most common type of bullying behavior among primary and junior middle school children. Gender differences existed in regard to the incidence of bullying others and being bullied, children's attitudes towards bullying and the types of bullying behavior they suffered.

Key words: bullying/victimization, bullies, victims, attitudes, type of bullying
