Background: With the increased empirical interest in the positive significance of improving nurses' sense of professional benefits, there is a requirement for measures of nurses' perceived professional benefit (NPPB). Our objective was to develop and psychometrically test a brief Nurses' Perceived Professional Benefit Questionnaire (NPPBQ).
Methods: After expert consultation and nurse interviews, a primary questionnaire was developed for an exploratory factor analysis (EFA). The seventeen items of the NPPBQ were used for verification of the theorized factor structure and content validity using a confirmatory factor analysis (CFA). The NPPBQ's concurrent validity was evaluated. Three samples of nurses were collected in Shanghai, Hangzhou and Nanjing between November 2017 and August 2018.
Results: The results of the EFA and CFA verified the five dimensions of nurses' occupational benefit discovery. The results demonstrated that the NPPBQ has adequate internal consistency and is fully consistent with the theorized factor structure. This 5-factor solution explained an adequate percentage of the total variance. The Cronbach's alpha of each dimension of the NPPBQ was good. The concurrent validity was significantly correlated with all aspects of the Maslach Burnout Inventory (MBI).
Conclusion: The results suggest that the NPPBQ is a psychometrically sound measure for evaluating perceived professional benefits among a wide range of nurses.
