The validity of the questionnaire was evaluated through concurrent and criterion validity, whereas its reliability was assessed by test re-test internal consistency and splitting method.Results: The internal consistency and test-retest reliability of IR-DAS-3 was acceptable (α= 0.78, α= 0.68). The IR-DAS-3 total score and its five subscales score were correlated with HbA1C levels (P<0.01); this supported the concurrent validity of the questionnaire.Conclusion: The psychometric properties of the IR-DAS-3 are acceptable and the scale is a good instrument for assessing the attitudes of the Iranian diabetic patients.https://jdmd.tums.ac.ir/index.php/jdmd/article/view/279https://jdmd.tums.ac.ir/index.php/jdmd/article/download/279/49
