Aim: To assess the psychometric properties regarding the Portuguese version of the
Practice Environment Scale of the Nursing Work Index.
Background: The Practice Environment Scale of the Nursing Work Index is the most
widely used measure for assessing the practice environment. A model with a higher
number of factors appears to be more adequate to Portuguese settings.
Method: A confirmatory factor analysis was performed to the Practice Environment
Scale of the Nursing Work Index using a sample of 850 Portuguese nurses. Three
models were tested: the original model, a seven-factor
model and a higher-order
model. An analysis of invariance was performed in two subsets to confirm the stability
of the solution.
Results: The seven-factor
model fit better to the data than the original model. After
refinement, this solution showed suitability and a stable factor structure. Reliability,
convergent validity and discriminant validity were confirmed. A second-order
factor
solution also showed suitability.
Conclusion: The seven-factor
structure of the Practice Environment Scale of the
Nursing Work Index showed a better goodness-of-
fit
to Portuguese settings than the
original structure. The second-order
factor solution allows an overall assessment of
practice environments.
Implications for Nursing Management: The Portuguese version of the Practice
Environment Scale of the Nursing Work Index is a valuable tool for assessing
Portuguese nursing practice environments. The seven-factor
solution of the Practice
Environment Scale of the Nursing Work Index showed high specificity.
