The purpose of this study is to investigate the effect of self-realization on psychological happiness in 225 college students majoring in contemporary dance and to verify the mediating effect of physical self-concept. To achieve the purpose of the study, 225 contemporary dancers enrolled in universities in the metropolitan and non-metropolitan areas were surveyed for about two weeks from November 27 to December 8, 2023. For data analysis, factor analysis, reliability analysis, multiple regression analysis, and mediated regression analysis were performed using the statistical program SPSS 18.0. As a result of multiple regression analysis, it was found that the ability development of self-realization and the purpose ideal had a positive (+) effect on the self-realization of psychological happiness, and the ability expression and the purpose ideal had a positive (+) effect on confidence, and the ability expression and the purpose ideal had a positive (+) effect on immersion, and the purpose ideal had a positive (+) effect on pleasure. As a result of mediated regression analysis, it was found that physique partially mediated the relationship between more than the purpose of ability expression, confidence, and immersion, and physical strength partially mediated the relationship between ability development, ability expression, more than the purpose and self-realization, immersion, self-confidence, and pleasure, and physical activity partially mediated the relationship between more than the purpose and confidence, and health partially mediated the relationship between ability expression and confidence. "Research results are accumulated in various ways related to self-realization and psychological well-being," and "research by adding variables, and use in-depth interviews" were derived as implications.
