The EuroQol Group first met in Rotterdam in May 1987 determined to develop a standardised non-disease-specific instrument for valuing health-related quality of life. The book traces the activities of the Group over the next 25 years. The instrument constructed, eventually named the EQ-5D, was translated into many languages and used in a wide range of countries and settings. The book describes how the instrumentâ€{u3824}escriptive system was determined, how translation and language issues were handled, and how valuations were provided. Recent developments, in particular a 5-level version (EQ-5D-5L), and a youth version (EQ-5D-Y) are covered. The history of the institutional and administrative framework within which the Group operated is also treated.
