Summary
The Professional Practice Work Environment Inventory (PPWEI) is a reliable and valid tool for assessing the nursing work environment. This psychometric evaluation confirms its sound measurement properties for healthcare research.
Area of Science:
- Nursing
- Healthcare Administration
- Psychometrics
Background:
- The Professional Practice Work Environment Inventory (PPWEI) was developed to measure eight components of the professional practice environment (PPE).
- It is derived from the Professional Practice Environment (PPE) and Revised PPE scales.
- The PPWEI aims to aid nurse administrators in decision-making processes.
Purpose of the Study:
- To evaluate the psychometric properties of the Professional Practice Work Environment Inventory (PPWEI).
- To determine the reliability and validity of the PPWEI for measuring the nursing work environment.
Main Methods:
- A psychometric evaluation was conducted with 874 nurses at Massachusetts General Hospital.
- The study utilized the newly developed 72-item PPWEI.
- Data from nurses providing direct patient care with no missing information were analyzed.
Main Results:
- The total score of the PPWEI demonstrated strong internal consistency reliability (Cronbach's α = .93).
- Principal component analysis identified 8 components, explaining 64.6% of the variance.
- Subscale reliability coefficients ranged from .82 to .93, with 61 items exceeding the factor loading cutoff of .50.
Conclusions:
- The PPWEI is a multidimensional, psychometrically sound instrument for assessing the professional practice environment in acute care settings.
- The PPWEI is sufficiently reliable and valid for use as independent subscales in healthcare research.
- This inventory supports evidence-based decision-making for nurse administrators.
