Rasch analysis informed the development of a classification system for a diabetes-specific preference-based measure of health
چکیده انگلیسی

ObjectiveTo develop a classification system (CS) for a diabetes-specific preference-based measure of health titled the Diabetes Utility Index (DUI).Study Design and SettingFactor analysis of the Audit of Diabetes-Dependent Quality-of-Life (ADDQoL) items (n = 385) identified plausible attributes. An expert panel provided qualitative input, including additional items. Data from three pilot rounds on patients with type 1 or type 2 diabetes were analyzed using Rasch analysis (RA). In a validation survey, the final version of the CS was mailed along with the SF-12v2, Well-Being Questionnaire, and Diabetes Empowerment Scale Short Form to a convenience sample (type 1 or type 2 diabetes).ResultsFactor analysis identified two plausible attributes. Experts rated the importance of ADDQoL and additional items, described attributes from item sets and suggested severity levels. Three pilot rounds (n1 = 52, n2 = 65, n3 = 111) tested versions of a CS, containing five attributes with severity levels that were modified using RA and expert input. The final attributes were Physical Ability and Energy, Relationships, Mood and Feelings, Enjoyment of Diet, and Satisfaction with Management of Diabetes. The validation survey (n = 396) results indicated satisfactory Rasch fit statistics, reliability, and severity scaling, whereas correspondence of responses to the CS with included measures suggested validity.ConclusionResults provide initial report of the validity and reliability of the CS of the DUI.
