Provision of patient-centered services is one of the values of any health care system. Patient-centered means giving importance to the patientchr('39')s rights and entitlements in all areas related to treatment and involving the patient in decisions throughout the process of rendering services to the patient. The purpose of this study was to translate and validate the Stewart Patient-Centered Questionnaire and to provide an appropriate and valid tool to assess the patient-centered rate in the provision of medical services.

The present descriptive methodological study was conducted in 2020. Initially, Stewart patient-centered questionnaire was translated using the forward-backward method. Later, the translated version was examined by the research team to establish cultural compatibility with Iranian culture. The validity of its content was assessed by obtaining the opinions of 15 health management specialists and its face validity was assessed by 15 patients. The internal reliability of the questionnaire was assessed using the opinions of 30 patients and Cronbachchr('39')s alpha coefficient was calculated using SPSS 22 software. The construct validity was assessed according to the opinions of 283 patients in the study population through STATA 15 software.

Based on the content validity results, all items of the main questionnaire had acceptable CVR and the CVI index was 0.87 for this questionnaire. The face validity also confirmed all the statements. Cronbachchr('39')s alpha coefficient of the whole questionnaire was calculated as 0.976 and thus the internal reliability of the questionnaire was confirmed. Based on the results of the confirmatory invoice analysis GFI (0.988), RMR (0.048), and CFI (0.984), the translated questionnaire had suitable construct validity and all questions were retained.

The questionnaire can be applied as a valid and applicable tool for assessing patient-centered care in the Iranian health care system.
