The NDNQI-Adapted Index of work satisfaction

Area of Science:

• Nursing Quality Indicators
• Healthcare Management
• Organizational Psychology

Background:

• Accurate measurement of nurse job satisfaction is crucial for retaining qualified nursing staff in hospitals.
• Job satisfaction directly impacts patient care quality and hospital operational efficiency.
• Existing tools required adaptation for unit-level assessment within national quality indicator databases.

Purpose of the Study:

• To adapt and validate the Stamps Index of Work Satisfaction for measuring work satisfaction at the patient care unit level.
• To ensure the adapted index is suitable for use by the National Database of Nursing Quality Indicators (NDNQI).
• To assess the reliability and validity of the adapted instrument in measuring nurses' job satisfaction.

Main Methods:

• Two studies involving Registered Nurses (RNs) were conducted.
• Study 1 utilized exploratory factor analysis (n=918) to replicate conceptual dimensions and assess reliability (theta=.91).
• Study 2 employed confirmatory factor analysis with structural equation modeling (n=2277) to support the 7-subscale structure and validity.

Main Results:

• Exploratory factor analysis replicated the original Stamps measure's dimensions.
• The adapted Work Satisfaction subscales explained a significant portion of the variance in Job Enjoyment (46% in Study 1, 56% in Study 2).
• Confirmatory factor analysis supported the 7-subscale structure of the NDNQI-Adapted Index, demonstrating good model fit (CFI=.88, RMR=.05).

Conclusions:

• The NDNQI-Adapted Index is a reliable and valid instrument for measuring work satisfaction at the patient care unit level.
• The adapted index demonstrates a similar structure to the original Stamps instrument.
• The feasibility of using an online version for data collection was confirmed, facilitating efficient data gathering.
