The main objective of this study was to compare and contrast adolescent and adult values for
the Child Health Utility-9D (CHU9D), a new generic preference based measure of health
related quality of life designed for application in the economic evaluation of treatment and
preventive programmes for children and adolescents. Previous studies have indicated that
there may be systematic differences in adolescent and adult values for identical health states
but have failed to use a common valuation technique. An on-line survey including a series of
best worst scaling discrete choice experiment questions for health states defined by the
CHU9D, was administered to two general population samples comprising adults and
adolescents respectively. The results highlight potentially important age related differences
in the values attached to CHU9D dimensions. Adults, in general, placed less weight upon
impairments in mental health (worried, sad, annoyed) and more weight upon moderate to
severe levels of pain relative to adolescents. The source of values (adults or adolescents) has
important implications for economic evaluation and may impact significantly upon health
care policy. Profile case best worst scaling offers a promising approach for the elicitation and
comparison of health state values across population groups.
