The purpose of this study was to examine the correlation between the school bullying and covert
narcissism of high school students and the mediating effects of their mode of anger expression on the
relationship between the two in an effort to provide some information on school intervention. The subjects in
this study were 280 selected high school students in South Gyeongsang Province and Gyeonggi Province. The
instruments used in this study were three scales that respectively dealt with school bullying, covert narcissism
and mode of anger expression. As for data analysis, a statistical package SPSS WIN 19.0 was employed. The
Cronbach alpha coefficients of the scales were calculated to test their reliability, and descriptive statistics
analysis was made including frequency analysis. To determine the correlation of the independent and
dependent variables and the effects of the mediator variable, regression analysis was made, and Sobel test was
conducted to verify the model.
The findings of the study were as follows: First, covert narcissism had a positive correlation with offending
and victimization that were the subfactors of school bullying. Covert narcissism was positively correlated with
anger expression and anger-in, and there was no significant relationship between it and anger control. Second,
concerning the mediating effects of anger expression(anger expression, anger-in and anger control) on
narcissism and school bullying(offending and victimization), anger expression, anger-in and anger control had
partial mediating effects on the relationship between covert narcissism and offending of school bullying.
Anger-in had partial mediating effects on the relationship between covert narcissism and victimization of
school bullying, but anger expression and anger control had no mediating effects on that. The findings of
the study suggest that every high school is required to offer more intensive support including appropriate
intervention in order for students to lead a healthy, sound school life and improve their peer relationship.
