Background and Objectives: Even though there are existing studies on the correlation between health literacy (HL) and lifestyle, to this day, the concept of Lifestyle health literacy (LHL) has not been considered. This study was conducted to design and evaluate the validity and reliability of the LHLQ among military bases of Tehran.Material and methods: In the present study, first the questionnaire was designed, and then the validity and reliability of the LHLQ in soldiers were evaluated from ۲۰۲۰ to ۲۰۲۱. The face and content validity and quantitative and qualitative content validity were performed and eventually ۳۳ questions were examined for reliability. The Cronbach’s alpha and Intra-class Correlation Coefficient (ICC) were used. Factor analysis was performed on ۳۰۰ soldiers who were available through four selected garrisons in Tehran.Results: The mean of CVI was ۰.۹۲ and CVR was ۰.۷۱. Also, in the ICC reliability study, the total questions were ۰.۸۵ and the Cronbach's alpha’s questions were ۰.۹۳. The exploratory factor analysis identified a ۶-factor structure of responsibility, nutrition, physical activity, stress control, spiritual growth, and interpersonal relationships for the LHLQ, which were plotted in ۳۳ terms and explained ۵۸.۵۸% of the total variance. The ۶ factors model was approved via the confirmatory factor analysis method X۲/df=۲.۹۷۴ RMSEA=۰.۷۷, GFI=۰.۸۷۰, and NFI= ۰.۹۰۲.Conclusion: The questionnaire's indices have an acceptable level of validity and reliability, therefore the soldiers' LHLQ can be used to measure the LHL of this group.
