Abstract

This study was undertaken to validate and assess the reliability of the Korean version of professional quality of life scale (K-ProQOL) that measures the compassion satisfaction, compassion fatigue and burnout among clinical nurses in Korea. We conducted an internal consistency reliability and construct validity by applying confirmatory factor analysis using SPSS WIN (24.0) and AMOS (18.0). Survey data were collected from 210 nurses working at three tertiary hospitals located in Seoul. Reliable internal consistency was achieved for the K-ProQOL, with a Cronbach's alpha for the total scale and three sub scale values of 0.72-0.90. Factor loadings on three subscales of the 30 items considered ranged from 0.25 to 0.82. The model was validated by confirmatory factor analysis (RMSEA 0.05-0.1, GFI >0.7, CFI >0.7). The findings of this study demonstrate that the K-ProQOL has satisfactory construct validity and reliability to measure compassion satisfaction, compassion fatigue and burnout among clinical nurses in Korea. This is the first study assessing the validity and reliability of the Korean version of professional quality of life scale for clinical nurses in Korea.

본 연구는 한국어판 전문직 삶의 질 측정도구(Korean version of professional quality of life scale : K-ProQOL)가 한국 간호사의 공감만족, 공감피로와 소진을 측정하기에 타당한 도구인지를 검증하는 방법론적 연구이다. 조사 자료는 서울에 위치한 3개의 상급종합병원에서 근무한 210 명의 간호사로부터 수집되었으며, SPSS WIN (24.0)과 AMOS (18.0)를 이용하여 확인적 요인 분석과 Cronbach 's alpha 검정을 통해 도구의 타당도와 신뢰도를 측정하였다. K-ProQOL의 RMSEA는 .09로 .05~.1 사이의 값을 보였으며 GFI와 CFI는 각각 .72와 .71로 모형 적합도 최소 기준인 .7 이상의 값을 보였다. 각 문항별 요인 적재량을 분석한 결과 .25에서 .82의 수준을 보였다. K-ProQOL의 Cronbach 's alpha는 .72로 각 하위영역인 공감만족, 공감피로, 소진의 Cronbach's alpha값은 각각 .90, .78, .75 수준을 보였다. 본 연구결과를 종합해 볼 때, K-ProQOL 도구는 한국 간호사를 대상으로 공감만족, 공감피로, 소진을 측정함에 있어 일부 문항들에 제한이 존재하지만 최소 기준의 타당도와 신뢰도가 확보되었다. 본 연구는 국내 최초로 간호사를 대상으로 K-ProQOL 도구의 타당도와 신뢰도를 검정한데 의의가 있다.
