Practice Environment Scale of the Nursing Work Index (5 items version): Translation and validation in Greek

Background: Measuring nurse work environments is essential to address the nursing shortage. Aim: To translate and validate the “Practice Environment Scale of the Nursing Work Index” (5 items version) in Greek. Methods: Study population included 80 nurses in Greece. We performed our study during August 2024. We employed the forward-backward method to translate and adapt the “Practice Environment Scale of the Nursing Work Index” (PES-5) in Greek language. We examined the construct validity of the PES-5 by performing confirmatory factor analysis. We examined the concurrent validity of the PES-5 using the “Quiet Quitting Scale” (QQS), the single item burnout measure, and the single item turnover intention measure. We examined the reliability of the PES-5 by calculating Cronbach’s alpha. Results: The PES-5 showed very good psychometric properties. Our confirmatory factor analysis confirmed the one-factor structure of the PES-5. Concurrent validity of the Greek version of the PES-5 was very good. We found a statistically significant negative correlation between PES-5 and QQS (r = -0.410, p-value < 0.001), and single item turnover intention measure (r = -0.227, p-value = 0.043). We found that the PES-5 had very good reliability since Cronbach’s coefficient alpha was 0.651. Conclusions: The Greek version of the “Practice Environment Scale of the Nursing Work Index” is a reliable and valid tool to measure the nursing practice environment.
