The purpose of this research was to adapt and validate the 6-items Academic Major Satisfaction Scale (AMSS, Nauta in J Career Assess 15(4):446-462, 2007) for use in Korea. The scale was tested using 275 college students in South Korea. Results indicated adequate internal-consistency reliability of 0.87, and adequate test-retest reliability of 0.84. Confirmatory factor analysis demonstrated a unidimensional structure and measure invariance tests showed equivalent structure across gender groups. Correlations with career decision self-efficacy and variables related to subjective well-being ranged from moderate-tohigh and were all significant. All the results suggest suitable fit among the population of Korean college students. Suggestions for usage of and future research on the AMSS in the Korean context are discussed.
