descriptions on the scale between the two anchors so that the intervals between the scores corresponded to the differences they perceive. The distribution of EQ-5D questionnaires and EQ-5D+C questionnaires was performed randomly. Analysis of the data included: Calculations of means and standard deviations for all valued health-state descriptions; Statistical testing within pairs (EQ-5D versus EQ-5D+C); Paired t-tests were performed for some health states i.e. health states; health states with level variations. Results of t tests for differences between the EQ-5D and EQ-5D+C showed significant differences in 2 cases: health state 11211(2) where a “moderate” cognition level was added to a state, and health state 12311(3) where “good“ a cognition level was added to a state. Adding a “bad“ “moderate“ “good” cognition level to a health state did not result in any meaningful “bad” improvements. Adding a cognition level to a health state resulted “bad” “bad” in a poor valuation.
