The purpose of this study was to examine the effects of narcissism on self-management and performance confidence among university students majoring in dance. A survey was conducted with dance majors enrolled in four-year universities in Seoul, and a total of 363 valid questionnaires were analyzed using SPSS Version 23.0. Data analysis included frequency analysis, exploratory factor analysis, reliability testing, correlation analysis, and multiple regression analysis. The findings are as follows. First, narcissism had a statistically significant effect on self-management. Second, narcissism significantly influenced performance confidence. Third, self-management had a significant positive effect on performance confidence. These results indicate that narcissism functions as a psychological resource that promotes self-management and enhances performance confidence among dance majors. The findings suggest that, within pre-professional dance training contexts, certain dimensions of narcissism may contribute positively to psychological stability and performance-related competence.
