Abstract: An investigation adopting Basic Empathy Scale, Moral Disengagement Scale, College Bullying Behavior Questionnaire, and Cyberbullying Inventory, which collected 1556 students responses in a college is conducted to explore the relations among empathy, moral disengagement, traditional bullying and cyberbullying. The results indicate that: (1) a. The variables of cognitive empathy, traditional bullying and cyberbullying are all significantly negatively correlated. b. Emotional empathy is significantly negatively correlated with the two variables of moral disengagement and cyberbullying, and it has no significant correlation with traditional bullying. c. Moral disengagement is significantly positively correlated with the two variables of traditional bullying and cyberbullying. (2) Cognitive empathy can directly make a negative prediction of cyberbullying, and it can also indirectly make a prediction of cyberbullying in three ways, i. e., the mediating effect of moral disengagement, the mediating effect of traditional bullying, and the chained mediating effect of moral disengagement and traditional bullying. (3) Emotional empathy may also directly make a negative prediction of cyberbullying, and it can also indirectly make a prediction of cyberbullying in two ways, i. e., the mediating effect of moral disengagement, and the chained mediating effect of moral disengagement and traditional bullying. On the basis of the Cues Filtered-out theory and the General Attack Model of cyberbullying, the study incorporates the factor of personal experience of traditional bullying, attempting to reveal the mechanism of cyberbullying.

Key words: empathy, cyberbullying, traditional bullying, moral disengagement
