Abstract
AimsThe aim of this study was to examine the reliability and validity of the Practice Environment Scale of the Nursing Work Index (PES‐NWI) for hospital nurses in Japan.DesignA cross‐sectional mail survey.MethodsParticipants in this study were 1,219 full‐time ward nurses from 27 hospitals in Japan, using 31 items of the Japanese version of the PES‐NWI questionnaire, from December 2008‐March 2009. Construct validity, criterion‐related validity and internal consistency of the PES‐NWI were tested.ResultsThe PES‐NWI showed reliable internal consistency. The five‐factor structure was supported by confirmatory factor analysis. The PES‐NWI correlated significantly with job satisfaction, burnout and the nurses’ intention to stay on the job, supporting criterion‐related validity.
Highlights
Like other countries, Japan is experiencing a nurse shortage at the same time its rapidly ageing population demands increasing nursing services for the older people
This paper presents the results of a national study in Japan that corroborated the reliability and validity of the PES-Nursing Work Index (NWI) in Japanese
A study of Registered Nurses (RNs) in US-based Army Medical Department hospitals showed that an unfavourable nursing practice environment was significantly correlated with job dissatisfaction, emotional exhaustion, intent to leave and poor quality of care (Patrician, Shang, & Lake, 2010)
Summary
Japan is experiencing a nurse shortage at the same time its rapidly ageing population demands increasing nursing services for the older people. To attract nurses to the workplace, the features of the practice environment are important. To quantify those features, useful instruments have been developed in the United States, such as the Nursing Work Index (NWI), the Revised Nursing Work Index (NWI-R) and the Practice Environment Scale of the Nursing Work Index (PES-NWI). Useful instruments have been developed in the United States, such as the Nursing Work Index (NWI), the Revised Nursing Work Index (NWI-R) and the Practice Environment Scale of the Nursing Work Index (PES-NWI) These are based on the features of so-called “magnet hospitals,” which, during a nursing shortage in the early 1980, were, like magnets, able to attract and retain well-q ualified nurses, while consistently providing high-quality care.
