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.

The purpose of this study was to investigate the effects of professional dancers' achievement goal orientation and self-management on their dance commitment. Subjects of the study were professional dancers working in one of the national, provincial, and municipal professional dance organizations located in Seoul, Kyeonggi-do, Incheon, Gangwon-do and Chungcheong-do, as of 2019. For the data collection, questionnaires based on self-administration were distributed to the study population. 325 samples were collected and used for the data analysis. Corelation analysis and multiple regression analysis were employed, and each hypothesis was tested at the a=.05 level of significance. Through these research methods and procedures, the following results were derived: First, self orientation of achievement goal orientation showed to have a significant effect on all of the subsidiary factors of self-management: mental management, personal relations, training management and physical management. Task orientation was found to have significant influence on mental management, and physical management. Second, self orientation of achievement goal orientation appeared to have significant influence on both of the subsidiary factors of dance commitment: cognitive commitment and behavioral commitment. However, task orientation did not show any meaningful effect on any of the subsidiary factors of self-management. Third, subfactors like training management, personal relations and mental management of self-management turned out to have a meaningful effect on both of the subsidiary factors of dance commitment: cognitive commitment and behavioral commitment. These results proved that professional dancers' achievement goal orientation and self-management were the factors that were significantly related to dance commitment. Therefore, as the higher and better the professional dancers' achievement goal orientation and self management are, the better their commitment to dance become, it will lead dancers to higher degree of perfection of dance performance and consequently bring high quality of performance to their audience.
