The aim of this study was to examine the normative dataand some of the psychometric properties of the Persian version of quality of life questionnaire in patientswith diabetes mellitus in an Iranian population.Materials and Methods: Subjects were DM patients who were referred to health centers of Isfahan city(Iran) in 2007. A total number of 120 diabetic patients were selected through stratified randomizedsampling as well as equal number of matched control subjects. A demographic questionnaire, diabetesquality of life (DQOL) and WHO- quality of life (WHO-QOL) tools were administered to both groups.Results: The total mean score of QOL was relatively low in DM patients except for the domains ofworries. Using the chronbach’s alpha test, the reliability of the whole questionnaire and its subscales weredetermined to be 0.89 and 0.51 to 0.84, respectively.
