This study examined the mediating and moderating effect of mindfulness through rumination on the relationship between evaluative concerns perfectionism and depression in early adults. For this study, an online self-report survey was conducted on 436 participants aged 19 to 35, and 405 participants (179 men, 226 women) were included in the final analysis. The mediating, moderating, and mediated moderating effects were verified using the PROCESS macro for SPSS v3.5. It was found that evaluative concerns perfectionism had a significant effect on depression, and this relationship was mediated by rumination. As a result, mindfulness (nonjudging of experience and acting with awareness) had a partially mediated moderating effect on the relationship between evaluative concerns perfectionism, rumination, and depression.
