The wear-and-tear hypothesis of caregiving (the longer care provided, the more psychological strain on caregivers) was examined using panel survey data from 112 adult children providing interhousehold care to an impaired elderly parent. Measures included subjective caregiving stress and perceived caregiving effectiveness ("wear") and depression and affect balance ("tear"). Contrary to the hypothesis, data revealed variability in children's adaptation to caregiving, improvement rather than deterioration being the norm. In a recursive path model, both subjective stress and perceived effectiveness were significant predictors of changes in depression. Depression was not significantly related to duration of caregiving. Discussion suggests that future researchers consider other types of caregivers and care settings, factors predicting variability in caregivers' adaptation over time, and changes as well as stability in care arrangements.
These results suggest that caregiver depression is closely linked to how well both the resident and caregiver adjust to the nursing home environment. Results also indicate that by broadening the SPM to include stressors common to the nursing home experience, researchers will be able to understand more clearly the specific components of the stress process that may lead to depression in family caregivers of persons living in nursing homes.
This investigation adapts the social support conceptual framework to examine the moderating influence of community service use by impaired older persons on the negative consequences of caregiving for informal helpers. The model is modified by defining services as a type of social support that can counteract the stress associated with various care recipient impairments. Results from multivariate analyses of data from 401 caregivers suggest that certain services for care recipients can reduce the adverse effects of certain impairments on informal caregivers. The use of health care service by care recipients who are more disabled is related to lower levels of caregiver depression, health deterioration, and social isolation. Personal care service use consistently offsets the negative effects of care recipients' behavioral problems. Additionally, the use of household service when care recipients exhibit behavioral problems is associated with lower levels of caregiver depression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
