Abstract: Objective: To translate the Ethical Decision-Making Confidence scale (EDMC) into Chinese and examine its reliability and validity, so as to provide an effective assessment tool for research on the ethical decision-making confidence of nurse managers in China. Methods: Following Brislin's model, the original scale was translated, back-translated, culturally adapted and pre-investigated to form the Chinese version of the EDMC scale. Using the convenience sampling method, a total of 433 head nurses from 8 general hospitals in Jinan were surveyed from September 2023 to January 2024 to evaluate the reliability and validity of the scale. Results: The Chinese version of the EDMC scale consisted of 2 dimensions and encompassed a total of 16 items, with a cumulative variance contribution rate of 66.310%. The results of confirmatory factor analysis showed that χ2/df=1.319, RMSEA=0.038, GFI=0.931, AGFI=0.909, NFI=0.943, indicating a good model fit. The item-level CVI of the EDMC was 0.975, and the scale-level CVI was 0.969. The correlation coefficient between the EDMC scale and the psychological empowerment scale was 0.752. The overall Cronbach's α coefficient of the scale was 0.933, while the Cronbach's α coefficients of the confidence in skill and behavior dimensions were 0.937 and 0.902 respectively. The Spearman-Brown broken half reliability coefficient was 0.906. The retest reliability of the scale was 0.881, and the retest reliabilities of the confidence in skill and behavior dimensions were 0.836 and 0.885, respectively. Conclusion: The Chinese version of EDMC has good reliability and validity and can be used as an assessment tool for the ethical decision-making confidence of nurse managers.
