Abstract

Objective To develop and test the Knowledge，Attitude and Practice Questionnaire for ICU Nurses on the Prevention and Management of Oral Mucosal Pressure Injuries（OMPI） in Orotracheal Intubation（OTI） Patients. Methods Based on the theory of knowledge，attitude and practice，the first draft of the questionnaire was developed through a literature review，semi-structured interviews，2 rounds of Delphi expert correspondence，and a pre-survey. 441 ICU nurses were recruited to take the survey from January to February 2024，the items were analyzed and reliability and validity were tested. Results A final questionnaire consisting of 3 dimensions and 36 items was developed. The exploratory factor analysis revealed that the cumulative variance contribution rate of the four common factors was 81.330%. The confirmatory factor analysis demonstrated that the chi-square degrees of freedom ratio（χ2/df） was 2.557，the root mean square error of approximation（RMSEA） was 0.084，the root mean square residual（RMR） was 0.040，the incremental fit index（IFI） was 0.912，the comparative fit index（CFI） was 0.912，and Tucker-Lewis Index（TLI） was 0.903，indicating good model fit. The average content validity index（CVI） of the questionnaire was 0.993，with item-level CVIs ranging from 0.875 to 1.000. The overall Cronbach’s alpha was 0.965，with split-half reliability of 0.730 and test-retest reliability of 0.981. Conclusion The questionnaire developed in this study has good reliability and validity and is suitable for investigating the current status of ICU nurses’ knowledge，attitude and practices regarding the prevention and management of OMPI in OTI patients.
