The purpose of this study was to translate and adapt a scale to evaluate social justice in nursing students and to examine the validity and reliability within a Korean context. With a survey design, a total of 267 nursing students were recruited, and data were collected using a self-administered study questionnaire to measure their levels of SJS. Using SPSS/WIN 28.0, construct validity, item convergent and discriminant validity, concurrent validity, and internal consistency reliability of the scale was evaluated. Exploratory factor analysis supported the construct validity with a four-factor solution; that explained 55.52% of the total variance. Criterion validity was demonstrated with the Social Issues Advocacy Scale (r = 0.78, <i>p</i> < 0.001). Cronbach's α coefficient for the scale was 0.96. The findings show satisfactory construct and criterion validity and reliability of the Korean version of the SJS for measuring social justice in nursing students.
