It
was the aim of this research project to investigate
the health of Australian women aged 70 years and over
who are caring for someone ill or disabled at home.
This sample of women was drawn from the Australian Longitudinal
Study of Women’s Health (ALSWH) which is a large
population-based mail-out survey examining aspects of
health in these women.
Study
one was cross-sectional in nature. Results of independent
t-tests indicated that caregivers (N= 851) reported
poorer mental health as compared to demographically
similar non-caregivers (N = 9 583), and no differences
between groups were found for self-reported physical
health. There were few observed differences between
these groups on measures of social support, stress and
personality traits. Results of hierarchical multiple
regression analyses indicated that health-related hardiness
(HRH), physical activity, social support, neighbourhood
satisfaction and income are important in fostering positive
ratings of mental health. Higher stress and the occurrence
of more than one major life event in recent years were
not helpful for caregiver mental or physical health.
HRH, physical activity and income were important in
fostering positive outcomes for self-reported physical
health. There was no support for any interactive or
moderating relationships.
Study two aimed to investigate caregiver health over
time where continuous non-caregivers were compared with
caregiving groups via linear mixed models analyses.
While the means for mental health for all caregiving
trends fell within the average range for Australian
norms, statistical analysis suggested a downward trend
over time for caregiver mental health. There was a lack
of definitive support for the adaptation hypothesis
as it stands at present, and there was no support for
improvement in mental health following cessation of
the caregiving role. Caregiving was not associated with
declines in self-reported physical health. However,
age was associated with declines in this domain, where
over time, all caregiving groups and the non-caregivers
reported worse physical health.
Implications for future caregiving research and for
social and health care policy are discussed.
