Background: School bullying is the most common type of school violence. Victimization by or perpetration of school bullying has frequently been associated with a broad spectrum of behavioral, emotional, and social problems.
Objective: To investigate the prevalence and demographic characteristics of victims, perpetrators, and victim-perpetrators in a Korean middle school sample.
Methods: We evaluated 1756 middle school students in this cross-sectional study. Students provided demographic information and completed the Korean-Peer Nomination Inventory. Descriptive statistics and the Pearson chi(2) test were used.
Results: We found that 40% of all children participated in school bullying. By category, the prevalence of victims, perpetrators, and victim-perpetrators was 14%, 17%, and 9%, respectively. The most common subtypes of victimization were exclusion (23%), verbal abuse (22%), physical abuse (16%), and coercion (20%). Boys were more commonly involved in both school bullying and all 4 types of victimization. The prevalence of bullying was greater in students with either high or low socioeconomic status and in nonintact families.
Conclusions: School bullying is highly prevalent in Korean middle school students. Demographic characteristics can help identify students at greater risk for participation in school bullying.
