The purpose of this study was to verify the mediating effect of accepting diversity in the effects of unconditional self-acceptance on gender equality consciousness in college students. To this end, a survey was conducted on 723 students (male: 405, female: 318) enrolled in a four-year university. For analysis, the collected data was verified using correlation analysis and a regression analysis procedure proposed by Baron & Kenny (1986), and bootstrapping was performed to verify the significance of the mediating effect. The research results are as follows. First, there was a significant correlation between unconditional self-acceptance, diversity acceptance, and gender equality consciousness. Second, in the relationship between unconditional self-acceptance and gender equality consciousness, the mediating effect of diversity acceptance was partially significant. Finally, the significance and implications of this study, and limitations for subsequent studies were suggested.
