ICECAP-CYP measures are in development for children and young people (CYP). Descriptive systems are being generated using in-depth interviews with parents (0-5), parents and CYP (6-15), and CYP (16-18). Descriptive systems are now available for the ICECAP-CYP:6-11 and ICECAP-CYP:11-15, and valuation studies using best-worst scaling are underway for both of these measures. Development work for the other measures is continuing.
