In most forms of evaluation the benefits of preventive health care are
narrowly defined in terms of reductions in future morbidity and morta
lity. Thus it is normally assumed that it is the final health gains al
one which bear utility. This discounts the possibility that individual
s may derive utility from the process of health care and other outcome
s as well as the end health states. Attributes such as anxiety, reassu
rance, autonomy, regret and hope provide potential benefits or disbene
fits in addition to health gains. This paper explores the concept of p
rocess utility in the specific context of preventive goods. Characteri
stics such as information, awareness and autonomy are examined for hiv
e preventive goods-hip protectors and mammographic screening. If indiv
iduals trade off process attributes for final health outcomes, then to
ignore process utility may lead to a sub-optimal allocation of resour
ces. (C) 1998 John Wiley & Sons, Ltd.
