Change in DTSQs: Individual Items and Total Treatment Satisfaction Score (6 of the 8 Items Summed)

Change from baseline (week 0) in Diabetes Treatment Satisfaction Questionnaire - status version (DTSQs) was evaluated at week 26 (wk 26) and week 52 (wk 52). The DTSQs items are scored on a 7-point graded response scale ranging from 6 to 0. Higher scores indicate higher levels of treatment satisfaction for DTSQs items 1, 4 -8. For items 2 and 3 a higher score indicates a higher patient perceived experience of hyperglycaemia and hypoglycaemia, respectively. Thus, lower scores indicate a perception of blood glucose levels being "none of the time" unacceptably high (item 2) or low (item 3). The domain score of total treatment satisfaction (total treatment satisfaction score) was computed by adding the six items scores 1, 4-8. The score has a minimum of 0 and a maximum of 36. A higher treatment satisfaction score indicates a higher level of treatment satisfaction.
