Economic evaluation of health promotion poses few major difficulties w
hen the theoretical approach of the programme and the evaluation of co
st and benefits are confined within the context of the individual. Met
hodological individualism has a long history in economics and the tech
niques of microeconomics are well suited to the examination of individ
ually focused behaviour change programmes. However, new developments i
n community health promotion pose special challenges. These programmes
have the community, not the individual, as the focus of programme the
ory and 'community' means something completely different from the sum
of individuals. Community empowerment and promotion of the community's
capacity to deal with health issues are the goals of such programmes.
To reflect these notions, sense of community and community competence
should be considered as 'functionings', an extra-welfarist constituen
t of well-being. Their inclusion as outcomes of community health promo
tion requires a shift from individualist utilitarian economics into a
communitarian framework which respects the programme's notion of commu
nity. If health economics fails to develop new constructs to deal with
these new approaches in health promotion, the application of existing
techniques to community programmes will mislead health decision maker
s about their value and potential.
