Since an estimate of the literacy level can be effective in increasing the level of personnel awareness of safe and health behavior, the purpose of this study is to provide a tool in the form of a valid and reliable questionnaire in the field of occupational health and safety literacy.

Materials and Methods: The current research was conducted to examine feasibility of the Persian version of the occupational health and safety literacy assessment questionnaire in employees in 2023. After translating the tool using the translation-retranslation, quantitative and qualitative validity of the questionnaire were assessed by 10 experts. Repeatability and internal consistency were examined by 30 employees, and item analysis as well as construct validity by 410 employees.

Results: The impact score, CVR and CVI of the questionnaire were 3.51, 0.96 and 0.91, respectively. The construct validity confirmed the final version of the questionnaire contains 34 questions in 4 dimensions including access, review, evaluation, and use of health and job information. The ratio of the chi-square test to the degree of freedom (χ2⁄df) was equal to 3.71. and the RMSEA index was 0.08. The internal consistency of the questionnaire was (⍺=0.923), and repeatability (ICC= 0.98) which were within the acceptable range. 

Conclusion: The Persian version of occupational safety and health literacy questionnaire with 34 items and 4 dimensions was confirmed by the concept of Iranian occupational safety and health literacy.
