Resumo:Background: Acceptance of diabetes is a psychological adaptation to the potential limitations of the disease. Poor acceptance of diabetes impairs efective self-management of diabetes, leading to worsening metabolic control. This study aimed at determining the psychometric properties of the Persian version of the Diabetes Acceptance Scale. Methods: This cross-sectional methodological study was performed on diabetic patients in Iran in 2021. The ques tionnaire consisted of two parts: demographic characteristics and Diabetes Acceptance Scale. The questionnaire was translated into Persian through the forward–backward translation method. The face validity and content validity were performed qualitatively and quantitatively. Exploratory (n=200) and confrmatory (n=200) factor analysis were performed to evaluate the validity of the structure. Internal consistency and temporal stability were estimated to determine reliability. Results: Exploratory factor analysis on the polychoric correlation matrix obtained three factors: Rational dealing, Resentment and Avoidance, which explained 68.8% of the total DAS variance. Confrmatory factor analysis showed that the 3-fractor model had a good ft to a second independent data set. Finally, Ordinal Cronbach’s alpha coefcient was 0.96, 0.94 and 0.93, respectively for the Rational dealing, Resentment, and Avoidance factor. Also, using intraclass correlation coefcient, the stability of the instrument was 0.97. Conclusion: Based on the fndings of this study, the Persian version of DAS has sufcient validity and reliability to measure the admission of Iranian diabetic patients
