Confirmatory factor analyses and assessments of reliability and construct validity were performed.Results: Study participants were 371 patients with type 2 (56% male; mean age, 57 years) and 481 with type 1 diabetes (57% male, mean age, 40 years). In both populations a four-factor model was the best fit. Cronbach’s α ≥ 0.79 and intraclass correlation coefficient ≥0.63; subscales correlated (P ≤ 0.05) with measures of well-being and satisfaction (0.12 ≤ r ≤ 0.71). In patients with type 1 diabetes, three subscales correlated (P < 0.05) with A1C.Conclusions: The psychometric properties of the DSC-R Cognitive Distress, Fatigue, Hyperglycemia, and Hypoglycemia suggest they may be utilized in clinical trials as reliable and valid measures of acute symptoms of diabetes.Keywords: Diabetes Symptom Checklist-Revised, DSC-R, type 1 diabetes, type 2 diabetes, psychometric validationNaegeli ANHayes CDove Medical PressarticleDiabetes Symptom Checklist-RevisedDSC-RType 1 DiabetesType 2 DiabetesPsychometric validationSpecialties of internal medicineRC581-951ENDiabetes, Metabolic Syndrome and Obesity: Targets and Therapy, Vol Volume 3, Pp 27-30 (2010)
