Influence of campus exclusion on bullying behavior of junior high school students: role of callous-unemotional traits and family caring

School bullying significantly impacts adolescent physical and mental development. The current study aimed to explore the effect of campus exclusion on school bullying behavior among junior high school students and the role of callous-unemotional traits and family caring. The Campus Exclusion Questionnaire, Olweus Child Bullying Questionnaire, Callous-Unemotional Trait Scale, and Family Caring Scale were completed by 705 students. A moderated mediation model was analyzed using SPSS 24.0. Results indicated that both campus exclusion and callous-unemotional traits positively predicted bullying behavior. Callous-unemotional traits partially mediated the relationship between campus exclusion and bullying behavior. Additionally, family caring moderated the link between callous-unemotional traits and bullying behavior, mitigating adverse effects. The study highlighted family caring's protective role against bullying linked to adverse school experiences. Therefore, collaboration between schools and families is crucial to reduce bullying.
