Abstract: PURPOSE: To construct the assessment scale of nurses' oral and maxillofacial trauma emergency response capacity and test its reliability and validity, providing a reliable and practical assessment tool for clinical oral and maxillofacial trauma training. METHODS: The assessment scale of nurses' oral and maxillofacial trauma emergency response capacity was designed based on literature review,expert consultation and Delphi method. Using the convenience sampling method, 328 nurses from Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine were selected in June 2022 for screening items and testing the reliability and validity of the constructed scale. SPSS 24.0 software package was used for data analysis. RESULTS: There were 2 rounds of Delphi expert consultations, including 6 experts, and the effective response rate of the questionnaire was 100%,with the Kendall harmony coefficients of 0.398 and 0.427（P<0.001）,and the authority coefficients of 0.967. The final assessment scale of nurses' oral and maxillofacial trauma emergency response capacity included 8 first-level indicators and 54 second-level indicators. The Cronbach's ɑ coefficient was 0.988, test-retest reliability was 0.817, I-CVI was 0.833 to 1.000, and S-CVI/Ave was 0.944. CONCLUSIONS: The assessment scale of nurses' oral and maxillofacial trauma emergency response capacity has good reliability and validity, which provides a scientific and practical evaluation tool for the development and verification of oral and maxillofacial trauma training system for clinical nurses.
