Abstract:
The increasingly diverse nursing workforce in the United States often creates challenges for researchers in meaningfully interpreting survey data from large samples of nurses with heterogeneous cultural backgrounds. Considering this, the purpose of this study was to determine the measurement invariance of the Practice Environment Scale-Nursing Work Index (PES-NWI) between registered nurses (RNs) reporting as Asian/Pacific Islander and those reporting as White. Data from the National Database of Nursing Quality Indicators®, collected in 2018 from RNs (N = 27,619) providing direct patient care, were used in this study. Multi-group confirmatory factor analysis was used to determine measurement invariance. Interpretation of the fit indices across models (configural, metric, and scalar) provides support for measurement invariance of the PES-NWI across the two groups. There is empirical support for pooling PES-NWI data and comparing it across these two groups.
