Screenshots of Task 2 from the Better-Worse (BW) and Drop-Down (DD) assessment and judgment tasks. For the BW method, respondents (i.e., patients) compared their own health states to five slightly different, alternative health states. With the exception of only two items, the alternative health states portrayed in Task 2 of the BW method did not differ from the actual health states as reported by the patients in Task 1. One of these items depicted an improvement of one level relative to the patient’s actual health state (depicted as a green box). Another item showed a reduction of one level relative to the patient’s actual health state (depicted as a red box). For the DD method, patients made multiple selections (2–5 times) of items at the levels that hindered or disturbed them the most. They did this by swiping (dropping down) the level and moving the item one level lower (i.e., better)
