There are several meanings of health outcome: the gap between attainme
nt and aspiration, the objective level of attainment, and the capacity
to adapt to changed circumstances, and each of these different meanin
gs reflect different value systems about the meaning of life. Existing
health measuring scales reflect one particular type of value system -
that health status is indicated by level of health complaint. Health
measurement is inevitably value dependent. Health measuring scales are
used in deciding how to allocate scarce health resources within healt
h care systems, and this process of resource allocation involves addit
ional value judgements, value judgements which should be made explicit
. Current health resource allocation decisions reflect a model of medi
cine where individual differences in response to treatment are discoun
ted. The biopsychosocial model is consistent with the suggestion that
individual differences in response to treatment and individual differe
nces in valuation of outcome should be expected, predicted, and should
be taken into account in resource allocation.
