Background: The aim of this study was to develop a valid and reliable instrument in order to measure self-management of type 2 diabetic patients.
Methods: Validity and reliability of Iranian version of Diabetes Self-Management Instrument (DSMI) measured through a cross-sectional study. Content validity, reliability, and cultural equivalency of Iranian version of DSMI were evaluated through a qualitative and quantitative study by 350 type 2 diabetic patients.
Results: Reliability and validity of the instrument and its 5 subscales, namely, "self-integration" (a=0.88), "self-regulation" (a=0.88), "interaction with health professionals and significant others" (a=0.79), "self-monitoring blood glucose" (a=0.92), and "adherence to recommended regimen" (a=0.87) were approved by a psychometric analysis. An intraclass correlation was satisfactory when a test-retest conducted among 150 patients by two weeks interval (p< 0.001). Criterion validity between total instrument and metabolic control Index (HbA1c) of type 2 diabetic patients was approved (p< 0.001).
Conclusion:  Study findings supported the reliability and validity of the Iranian version of DSMI for measuring self-management among Iranian people with type 2 diabetes in order to set appropriate interventions.
