Hope Mediates Stress to Reduce Burden in Family Caregivers of Persons with Alzheimer's Disease.

The experience of burden among family caregivers of persons with Alzheimer's disease and other forms of dementia may be deleterious for their health and well-being. Little is known, however, about the degree to which internal positive psychological resources, such as hope, influence burden perceptions in this population. The current study is novel in that it examined how multiple dimensions of hope, hope-agency and hope-pathway, influenced burden in a sample of one-hundred and fifty-five family caregivers of persons with Alzheimer's disease. The stress process model was used as the theoretical framework for variable specification in this study. Hope was conceptualized using Snyder and colleagues' hope theory. Supporting our first hypothesis, we found that burden was negatively associated with hope-agency, r = -0.33, p < 0.001 and hope-pathway, r = -0.24, p < 0.01. Multiple regression was used to determine if hope-agency and hope-pathway independently contributed to burden. Analysis revealed that hope-agency but not hope-pathway influenced burden when other key variables were taken into consideration. Findings from mediation analysis affirmed that hope-agency had a small but significant mediation effect between stress and burden in this sample. This study provides evidence for the relevance of assessing multiple dimensions of hope when working with caregivers of persons with Alzheimer's. Although replication studies are warranted, the current study confirms a need for further development and refinement of hope-bolstering behavioral interventions which may mediate stress and burden in this population. These interventions should be systematically assessed for efficacy and effectiveness via implementation studies in real-world settings.
