The structure of the Italian version of the Practice Environment Scale of the Nursing Work Index.

ABSTRACT

AIM: To investigate the factor structure of an Italian translation of the Practice Environment Scale of the Nursing Work Index (PES-NWI). BACKGROUND: Italy suffers from high turnover rates, yet validated tools in Italian to study and manage the problem are lacking. The PES-NWI measures aspects of nurses' working environment. This study reports on the translation and investigation of the structure of the translated PES-NWI scale. METHODS: A survey was conducted with 3667 nurses from 182 hospitals across 13 Italian regions using the PES-NWI. The structure of this scale was investigated using principal components analysis and other properties, including internal consistency (Cronbach's alpha). Construct validity was investigated using logistic regression. RESULTS: The Italian translation of the PES-NWI showed a five-factor structure, and Cronbach's alpha of the factors ranged between 0.80 and 0.92. Logistic regression showed that the PES-NWI was positively related to job satisfaction (odds ratio = 10.3; CI 8.62-12.35) and negatively related to intention to leave (odds ratio = 0.14; CI 0.12-0.16). CONCLUSIONS: The original five-factor structure of the PES-NWI was evident in the present study, albeit with some different factor loadings. IMPLICATIONS FOR NURSING MANAGEMENT The Italian version of the PES-NWI can be used by nurse managers to tackle the workforce issues related to nurses' work environments in a major European country.
