School bullying among U.S. adolescents includes physical, verbal, relational, and cyber forms. A study using data from the 2005 HBSC survey found that 20.8% of adolescents bullied others physically, 53.6% verbally, 51.4% relationally, and 13.6% electronically. Boys were more involved in physical and verbal bullying, while girls were more involved in relational bullying. Boys were more likely to be cyber bullies, while girls were more likely to be cyber victims. African-American adolescents were more involved in bullying but less likely to be victims. Higher parental support was associated with less involvement in bullying, while having more friends was linked to more bullying and less victimization in traditional forms but not cyber bullying. The study examined the roles of parental support and number of friends in bullying. Parental support was negatively associated with bullying involvement across all forms. Having more friends was linked to increased bullying and decreased victimization in traditional forms but not cyber bullying. The study also found gender differences in bullying behaviors, with boys more involved in physical or verbal bullying and girls in relational bullying. Age differences were consistent across traditional bullying forms, with 7th/8th graders less likely to be victims. Cyber bullying did not vary by grade, with 9th/10th graders being less likely to be bullies. The study highlights the distinct nature of cyber bullying compared to traditional forms. While traditional bullying is associated with social factors like friends and parental support, cyber bullying is not. The study also found racial differences, with African-American adolescents more likely to be bullies but less likely to be victims. Higher socioeconomic status was associated with less physical victimization but increased risk of cyber victimization. The study's findings suggest that parental support and friends play important roles in bullying prevention. However, the distinct nature of cyber bullying indicates the need for targeted interventions. The study also emphasizes the importance of considering demographic factors and different forms of bullying when developing interventions. The study's limitations include its cross-sectional design and reliance on self-report data. Despite these limitations, the study provides valuable insights into the prevalence and correlates of bullying among U.S. adolescents.School bullying among U.S. adolescents includes physical, verbal, relational, and cyber forms.
