The financial, opportunity and social costs and benefits of providing
informal support to frail older people are described within an economi
c framework. Mentally and/or physically frail older people were identi
fied through screening interviews with random community samples of peo
ple aged 65 and over in four UK areas: 884 frail older people living i
n private households nominated key informal supporters and 650 of thes
e supporters were interviewed. Around half the supporters reported fin
ancial costs (43 per cent) or lost social opportunities (45 per cent).
A minority of supporters had reduced their working hours or withdrawn
from employment because of caregiving. Nearly all supporters reported
at least one social cost (92 per cent) and identified at least one po
sitive aspect of caregiving (95 per cent). Go-resident supporters were
more likely to report opportunity costs and loss of health and well-b
eing. Daughters supporting a frail parent were generally most likely,
and friends or neighbours least likely, to report each type of cost. S
upporters of older people who were both mentally and physically frail
reported significantly greater opportunity and social costs. The benef
its of caregiving were not consistently related to co-residency, relat
ionship of supporter or frailty type. Possible strategies for decreasi
ng the costs and increasing the benefits of caregiving are discussed.
