Abstract: Objective To compile the health information literacy scale of military training injuries for grassroots officers and soldiers,test its reliability and validity. Methods Based on the knowledge-attitude-practice model and the framework of health information theory,the entry pool was formed through literature analysis,qualitative research and theoretical analysis from May to December 2023,and the pre-test scale was formed through two rounds of Delphi expert letter inquiry and small sample testing. Using the convenience sampling method,476 grassroots officers and soldiers of an unit were selected from January to May 2024,to test the reliability and validity of the questionnaire. Results The final constructed formal scale covered six dimensions with 30 entries,the exploratory factor analysis extracted six common factors,and the cumulative variance contribution rate was 75.888%. The confirmatory factor analysis showed that the structure of the scale factors was stable. The total table Cronbach's α coefficient was 0.954,the half reliability was 0.918,and the retest reliability was 0.928. The total scale content validity index was 0.985,and the content validity of each entry was 0.889-1.000. Conclusion The health information literacy scale of military training injuries of grassroots officers and soldiers has good reliability and validity,which has guiding significance for the health education of military training injuries,and is worth popularizing and applying.
