Health Literacy Organization in Iran.Materials and Methods: This research was a cross-sectional descriptive analytic study that was conducted on the tool of the
Health Literacy Organization that was designed during previous studies. First, the face validity assessment of the checklist was checked by ۲۲ experts. Then, the content validity was done using the relative coefficient of content validity rate and the content validity index by ۲۲ experts in the field of
health literacy who have favorable clinical and technical university experiences. In the third stage, in order to evaluate the calculation of the reliability coefficient, the instrument was performed by two evaluators in ۱۲ environments, including three hospitals, two clinics, five comprehensive
health service centers and two pharmacies.Results: During the content validity phase, ۶ questions were removed from the list of ۶۷ questions, and ۳ questions were structurally modified. The questionnaire had a CVI of ۰.۹۱۹ and a CVR of ۰.۷۸۱. The score of the reliability coefficient for the checklist was ۰.۹۴, and if this index is higher than ۰.۸, it indicates a very favorable reliability. Ultimately, the checklist of ۱۰ attributes and ۶۱ questions was approved.Conclusion: The evaluation checklist of
Health Literacy Organization has the necessary psychometric features. Hence, it is suggested to use this tool, which is a native tool and has been prepared during various studies in Iran, to design and measure the organization of
health literacy.
