Abstract

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.
