Objective To translate the Toxic Leadership Behaviors of Nurse Managers (ToxBH NM) scale into simplified Chinese and to test the reliability and validity. MethodsFollowing the Brislin′s model, the original scale was translated, back translated, culturally adapted, and pretested to create the Chinese version of the ToxBH NM scale. A total of 501 nurses in Guizhou Province were selected using convenience sampling and were surveyed to evaluate the reliability and validity of the scale. ResultsThe Chinese version of the ToxBH NM scale consisted of 30 items, and exploratory factor analysis revealed four common factors with a cumulative variance contribution rate of 65.200%. Confirmatory factor analysis showed good model fit indices:χ2/df=1.639, RMSEA=0.036, CFI=0.974, TLI=0.972, and IFI=0.974. The average scale level content validity index was 0.946, and the criterion related validity was 0.669 when using the Workplace Bullying Questionnaire as the criterion. The Cronbach′s α coefficient was 0.951, the split half reliability was 0.831, and the test retest reliability was 0.959. ConclusionThe Chinese version of the ToxBH NM scale is valid and reliable for measuring toxic leadership behaviors of nurse managers in the cultural context of China.
