Psychometric properties of a new instrument for assessment of treatment satisfaction in insulin-requiring diabetic patients, specifically adapted for evaluation of potential advan…

Sensitive instruments are needed to assess the effects of minor treatment changes resulting e.g. from a change of an insulin preparation. To assess such small improvements in diabetic patients treated with Functional Insulin Treatment (FIT) targeting on full flexibility of food intake and life style by appropriate choice of insulin dosage for correctional, prandial or basal purposes, we extended the Status (S) version of the DTSQ (Diabetes Treatment Satisfaction Questionnaire; Bradley, 1994) with items measuring specific FIT components of short-acting insulin (Howorka and Bradley, 2000) and recently for the dela…
