Relational bullying is a form of indirect bullying that often occurs in schools, involving acts of exclusion, neglect, spreading negative rumors, gossip, and social manipulation. This research aims to develop a theoretical model of relational bullying and determine the influence of extraversion personality, peer conformity, and school climate on it in boarding students. This research uses a quantitative approach. The study involved 210 madrasah tsanawiyah students boarding at Makrifatul Ilmi and Al Quraniyah Islamic boarding schools in South Bengkulu Regency. The (...) results showed that theoretical models of influence can influence relational bullying among students. The R square value was 0.68, indicating that personality variables extraversion, peer conformity, and school climate can explain relational bullying by 68%. Extraverted personality had a positive effect on relational bullying, peer conformity had a positive effect, and school climate had a positive effect. This research contributes to the development of a more specific relational bullying theory model in psychology and suggests a holistic approach that includes guidance and counseling for teachers, collaboration between parents and the school, socialization and education for interventions to overcome relational bullying behavior.
