Abstract: Objective: To cross-culturally adapt the Nurse-Doctor Professional Communication Questionnaire (NDPCQ) into Chinese and test its reliability and validity, so as to provide an evaluation tool for the professional communication atmosphere of medical staff in operating room in China. Methods: The English version of NDPCQ was translated according to the Brislin principle, and the content validity of the Chinese version of NDPCQ was evaluated by eight experts. From October 2023 to February 2025, 1142 operating room medical staff were surveyed using the Chinese version of NDPCQ to test its reliability and validity. The random splitting method was adopted, with 450 questionnaires utilized for exploratory factor analysis and 692 questionnaires for confirmatory factor analysis. Results: The Chinese version of NDPCQ consisted of 4 dimensions and 33 items. The content validity index I-CVI of each item was 0.875-1.000, and the S-CVI/Ave was 0.968. The results of confirmatory factor analysis showed that χ2/df=3.399, RMSEA=0.059, CFI=0.926, TLI=0.919, IFI =0.926, and GFI=0.863. The Cronbach's α coefficient of the total scale was 0.945, the split-half reliability was 0.817, and the test-retest reliability was 0.855. Conclusion: The Chinese version of NDPCQ demonstrates adequate reliability and validity, and can be used as an effective tool to evaluate the professional communication atmosphere of medical staff in operating rooms in China.
