摘要：This study analyzed differences of role behaviors of participants in bullying according to bystanders' characteristics. Participants were 112 5',6" and 7" grade students. Bystanders' characteristics of empathy, negative atitudes about bullying,psychological burden,distoting of consequences,and attibution of blame were classified by K-Means Cluster Analysis into three groups with similar characteristics : lack of empathy/cognitive distorting,ani-ullyig,and perception of cost groups. Major findings were that : the lack of empathycognitive distoring group had higher levels of bullying behavior than the ani-bllying group and higher levels of victimization than the perception of cost group. The ani-iulling group showed higher levels of defense behavior than the lack of empathy/cognitive distorting group. Implications for future research were discussed.
