This study aims to examine how self-compassion affects depression, subjective happiness and whether counseling majors differ from students in other majors in the effects of self-compassion on depression and subjective happiness. For the analysis, 148 students majoring in counseling, 187 students majoring in other majors at four-year universities in Busan and Jeolla Province were surveyed on depression, subjective happiness, self-compassion. Descriptive statistics, correlations, t-tests, hierarchical regressions were performed. First, the results showed that higher self-compassion was associated with lower depression and higher subjective happiness in college students. Second, the effects of self-kindness and over-identification on depression were significantly higher for counseling majors than for undergraduates in other majors. Third, the impact of self-judgment and over-identification on subjective happiness was significantly higher for counseling majors than for non-counseling majors. Based on these findings, the importance of self-compassion and ways to improve it for the mental health of counseling majors were discussed.
