We explored in an experimental setting whether such discrepancies in values for health states exist. It was hypothesized that the more the measurement strategy was incorporated in measurement theory the more similar the responses of patients and healthy people would be. Methods A sample of the general population and two patient groups cancer rheumatoid arthritis were included. All three study groups judged the same 17 hypothetical EQ-5D health states each state comprising the same five health domains. The patients did not know that apart from these 17 states their own health status was also included in the set of states they were assessing. Three different measurement strategies were applied 1 ranking of the health states 2 placing all the health states simultaneously on a visual analogue scale VAS 3 separately assessing the health states with the time trade-off TTO technique. Regression analyses were performed to determine whether differences in the VAS and TTO can be ascribed to specific health domains. In addition effect of being member of one of the two patient groups and the effect of the assessment of the patients own health status was analyzed. Results Except for some moderate divergence no differences were found between patients and healthy people for the ranking task or .
