OBJECTIVES: School bullying is known to be related to behavioral, emotional and social problems both in victims and perpetrators. The aims of this study are to develop a Korean-Peer Nomination Inventory(K-PNI), which can identify victims and perpetrators of school bullying in an objective and effective way, and to examine its reliability and validity. METHODS: Fourth to 6 th graders of two elementary schools in An Yang city completed K-PNI, Peer Acceptance Scale and Self-Perception Scale. Varimax Rotation Factor Analysis, Cronbach's Alpha Reliability Analysis and Pearson's Correlational Analysis were performed for statistical analyses. RESULTS: Total of 532 students(male:female=1:1;4 th:5 th:6 th grader=1:1:1.2) participate in this study. Factor analysis showed that K-PNI identified victims and perpetrators of school bullying effectively with excellent reliability(Chrobach's alpha;0.90-0.94). Victims were further divided into two categories;passive bullying including exclusion and verbal abuse, and active bullying including physical abuse and being forced. K-PNI, Peer acceptance scale and Self-perception scale were significantly correlated, reflecting its validity identifying victims and perpetrators of school bullying. CONCLUSION: K-PNI is an effective tool with excellent reliability and validity to identify victims and perpetrators of school bullying. K-PNI is expected to be a useful tool in future studies of school bullying and school violence.
