Development and validation of Nurse Managers’ Empowering Behavioral Scale for staff nurses

AIM: In this study, we developed and verified the Nurse Managers’ Empowering Behavioral Scale for Staff Nurses (NMEB‐SN). DESIGN: A cross‐sectional survey. METHODS: The NMEB‐SN was developed based on the staff nurses’ perspectives. Nurses working in 10 hospitals in Japan were surveyed using a questionnaire to test the scale's validity using construct and criterion‐related validity and reliability using internal consistency and test–retest method. There were 1,146 eligible participants included in the process. RESULTS: The scale items resulted in five subscales comprising of 48 items altogether. The goodness‐of‐fit indices for confirmatory factor analysis were CFI = 0.903 and RMSEA = 0.076. The correlation with external criteria for criterion‐related validity was near the expected standard. Further, Cronbach's α coefficient was 0.95–0.97 for each subscale and 0.99 for the overall scale. The reliability and validity of the developed NMEB‐SN were verified for staff nurses in Japan.
