The goal of this study was to examine the factorial structure, internal consistency, test-retest reliability, criterion validity, convergent validity, and discriminant validity of the Brief Strengths Scale-12 (BSS-12) in Korean population. The Korean sample comprised 288 college students (68.1% were female), ranging in age 19 to 30 years (mean age = 21.65 years, SD = 1.98). Results showed that a three-factor model with exploratory structural equation modeling provided a better model fit than the other competing models. Indices of internal consistency reliability, criterion validity, convergent validity, and discriminant validity of the BSS-12 were acceptable. These results suggest that the BSS-12 can be used as an effective tool for measuring character strengths in Korean population.
