[Acceptance and understandability of various methods of health valuations for the chronically ill: willingness to pay, visual analogue scale and rating scale].
Health valuations are one way of measuring patient preferences with respect to the results of their treatment. The study examines three different methods of health valuations--willingness to pay (WTP), visual analogue scale (VAS), and a rating question for evaluating the subjective significance. The goal is to test the understandability and acceptance of these methods for implementation in questionnaires. ⋯ With respect to understandability and acceptance, VAS questions appear to be better suited for reflecting patient preferences than WTP questions. The rating scale for assessing the personally estimated importance was understandable, but had poor distribution properties and was considered by patients to be superfluous.
