The purpose of this study is to measure the validity and reliability of the Korean version of the self-efficacy for restorative care activity (K-SERCA) scale and the outcome expectations for restorative care activity (K-OERCA) scale. Psychometric testing was given to 187 nurses who have worked in 69 long-term care facilities in South Korea via post service and personal visit. Data were collected via structured-questionnaire and analyzed using SPSS/WIN 21.0 and AMOS 22.0. Content, construct validity using confirmatory factor analysis (CFA), criterion validity and internal consistency reliability were conducted. The K-SERCA scale had factor loading of the 10 items ranged from .74 to .87, and was validated by confirmatory factor analysis (CFI=.96, NFI=.94, RMSEA=.10). The K-SERCA scale was also a significantly positive correlation with 'Job satisfaction' (r=.32, p<.001). There was a reliable internal consistency with a Cronbach's ${\alpha}=.94$. The K-OERCA scale had factor loading of the 9 items ranging from .38 to .95, and was validated by confirmatory factor analysis (CFI=.98, NFI=.96, RMSEA=.09). The K-OERCA scale was also a positive correlation with 'Knowledge (r=.26, p<.001)', and 'Job satisfaction (r=.30, p<.001)'. There was a reliable internal consistency with a Cronbach's ${\alpha}=.89$. The results demonstrate that the K-SERCA and K-OERCA scales had satisfactory validity and reliability to measure self-efficacy and outcome expectations for restorative care activities among nurses who have worked in long-term care facilities in South Korea.
