The Practice Environment Scale of the Nursing Work Index (PES-NWI) includes 31 items scored as 5 subscales and an overall score. The National Quality Forum (NQF) adopted the PES-NWI within a set of nursing sensitive measures. The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) in 2006 published an implementation guide and will add the measure set to ORYX in 2008. The National Database of Nursing Quality Indicators (NDNQI) which supports Magnet Recognition shares the NQF goal of common measure sets, including a measure of work environment. Thus the PES-NWI is a measure of considerable importance to hospitals across the country. Unfortunately the factor structure of this PES-NWI is a topic of considerable discussion. To date there has been limited independent testing of the PES-NWI. The purpose of this study was to examine the factor structure of the PES-NWI in a sample of 3113 nurses working in 5 hospitals of varying type (academic, community) and US geographic locations (Midwest, Southeast, Southwest). A convenience sample of RNs was surveyed using an email letter of introduction and consent for research, a follow-up email, and a web-based survey tool. Principal components analysis with orthogonal rotation was conducted. Factors with eigenvalues > 1.0 and items with factor loadings > 0.5 were used to construct subscales. Subscales thus obtained were compared to published reports of the PES-NWI and related work environment measures. We obtained a mean response rate of 40% across hospitals. Six factors were identified; one overriding factor explained 37% of the variance and with five additional factors cumulatively explained 60% of the variance. Items that loaded on the top three factors in our analyses overlap with items on three of the five subscales of the original PES-NWI. These results persisted across analyses by hospital and practice specialization. We have demonstrated a minimal level of support for three of the five subscales of the PEW-NWI as published for use by the NQF. Of considerable concern is the ability to explain only 60% of the variance. This finding suggests that further measure development and/or refinement is required prior to use of this measure as a comparison metric across hospitals.
