Abstract Background Timely initiation of insulin therapy in type 2 diabetes is important to achieve metabolic control but can be hindered by negative perceptions of patients regarding insulin treatment.

Methods A sample of 282 patients with type 2 diabetes form the United States US completed the ITAS the WHO-5 Well-being index WHO-5 and the Problem Areas in Diabetes PAID Survey. Exploratory factor analysis EFA internal consistency Cronbach s alpha and item-total correlations were determined to test the reliability of the instrument. Concurrent validity was examined by calculating Pearson correlation .
