The health-related quality of life (HRQoL) instrument
This website provides information of the 15D, its properties and usage.
The 15D is a generic, comprehensive (15-dimensional), self-administered instrument for measuring HRQoL among adults (age 16+ years). It combines the advantages of a profile and a preference-based, single index measure. A set of utility or preference weights is used to generate the 15D score (single index number) on a 0-1 scale. In most of the important properties the 15D compares favourably with other preference-based generic instruments.
Based on the 15D, a version has also been developed for adolescents aged 12-15 years (16D, is also used up to the age of 18) and for children aged 8-11 (17D, with parent-administration even younger).
