%X Background This study was designed to determine the primary psychometric properties of the Iranian version of the Diabetes Empowerment Scale (IR-DES-28). Methods After translating the questionnaire into Persian, re-translating it into English and obtaining the confirmation of the diabetes specialists regarding the accuracy of the translated questionnaire, 100 patients with type 2 diabetes selected using a systematic random sampling method completed the Iranian-DES-28. The validity of IR-DES-28 was evaluated by construct, concurrent and criterion validity, whereas its reliability was assessed by test re-test, internal consistency and splitting method. Results Psychometric analysis confirmed the reliability and validity of the IR-DES-28 in three subscales: Self-awareness and managing psychological aspects of diabetes (¦Á=0.80), goal achievement ability (¦Á=0.50), the ability of setting goals (¦Á=0.79). Test-retest reliability, evaluated through Pearson coefficient correlation, was equal to 0.74 (P <0.01). The total score of IR-DES-28 and that of the extracted subscales were correlated with HbA1c levels (metabolic control) (P <0.01). The findings also supported the concurrent validity of the questionnaire. Conclusion The validity and reliability of the Iranian-DES scale is acceptable. Thus, the scale could be an appropriate instrument in evaluating the empowerment-based education programs.
