This study aimed to examine the validity and reliability of Korean versions of the Nursing Assistant Self-Efficacy for Restorative Care Scale, and the Nursing Assistant Outcome Expectations for Restorative Care Scale. Psychometric testing was performed with 697 direct care workers in long-term care facilities in South Korea. Data were analyzed using SPSS/WIN 21.0, AMOS 22.0, and WINSTEPS 3.68.2. There was evidence for content validity. Factor loading in the Korean versions of the Nursing Assistant Self-Efficacy for Restorative Care Scale was 0.66–0.94, and Nursing Assistant Outcome Expectations for Restorative Care Scale was 0.43–0.77. Scores on the Korean versions of the Nursing Assistant Outcome Expectations for Restorative Care Scale correlated positively with scores on a scale of knowledge of restorative care. Additionally, Rasch model analysis of the K-NASERC and K-NAOERC indicates acceptable item data fit. These results indicated that the Korean versions of the Nursing Assistant Self-Efficacy, and Outcome Expectations for Restorative Care Scale are satisfactorily valid and reliable for the measurement.
