Background: Adolescents who have experienced peer victimization face a higher risk of negative health outcomes. However, little is known about the factors that are associated with peer victimization among adolescents in Taiwan. Purpose: The aim of this study was to examine the factors related to peer victimization among Taiwanese adolescents. Methods: A cross-sectional design was employed. Three hundred seventy-seven adolescents aged 13Y16 years from seven middle schools in southern Taiwanwere recruited as participants. Validated, self-reported questionnaires were used to gather data on demographic characteristics, resilience, peer relationship, parental monitoring, school connectedness, social support, and peer victimization. Logistic regression analysis was used to examine the factors that were related to peer victimization. Results: About 17% (n = 64) of the participants experienced peer victimization during the previous 1-year period. Logistic regression analysis indicated that parental monitoring of daily life, school connectedness, and peer support were significant predictors of a reduced risk of peer victimization. The final model explained 23.1% of the total variance in less peer victimization and predicted 80.1% of peer victimization. Conclusions/Implications for Practice: School connectedness and peer support were identified as important factors facilitating the avoidance of peer victimization among adolescents in Taiwan. Healthcare providers and school personnel should consider school-based programs to improve school connectedness and to build an atmosphere of peer support to reduce peer victimization. Educating parents to monitor their adolescents’ daily activities is also encouraged in concert with these school-based programs.
