Publication: EuroQol--a new facility for the measurement of health-related quality of life. The EuroQol Group
In the course of developing a standardised, non-disease-specific instrument for describing and valuing health states (based on the items in Table 1), the EuroQol Group (whose members are listed in the Appendix) conducted postal surveys in England, The Netherlands and Sweden which indicate a striking similarity in the relative valuations attached to 14 different health states. The data were collected using a visual analogue scale similar to a thermometer. The EuroQol instrument is intended to complement other quality-of-life measures and to facilitate the collection of a common data set for reference purposes. Others interested in participating in the extension of this work are invited to contact the EuroQol Group.
