Akzeptanz und Verständlichkeit verschiedener Methoden der Gesundheitsbewertung bei chronisch Kranken: Willingness to pay, visuelle Analogskala und verbale Ratingskala

Abstract

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.
