Abstract

Purpose

To develop and test the validity and reliability of the Korean version of PES-NWI measuring nursing work environments in hospitals.

Methods

The Korean version of the PES-NWI was developed through forward-backward translation techniques, and revision based on feedback from focus groups. An internal consistency reliability and construct validity using confirmatory factor analysis were conducted using SPSS WIN (16.0) and AMOS (18.0). Survey data were collected from 733 nurses who worked in three acute care hospitals in Seoul, South Korea.

Results

The Korean version of PES-NWI showed reliable internal consistency with a Cronbach's alpha for the total scale of .93. Factor loadings of the 29 items on the five subscales ranged from .28 to .85. The five subscales model was validated by confirmatory factor analysis (RMR<.05, CFI>.9).

Conclusion

The findings of this study demonstrate that the Korean version of PES-NWI has satisfactory construct validity and reliability to measure nursing work environments of hospitals in Korea.
