Exploring caregiving stressors and informal resources among Alzheimer's caregivers

Background: We use Pearlin's Stress Process Model to examine the objective stressors and subjective burdens of caregiving among family members who care for people with Alzheimer's disease. We ask how these factors are related, whether and how these factors are related to caregivers’ depressive symptoms, and whether their impact on caregivers’ mental health is reduced by caregivers’ informal resources. Methods: OLS regression analyses were used to examine the processes hypothesized by the stress process model using baseline and screen data from the Resources for Enhancing Alzheimer's Caregiver Health II (REACH II) study. Analysis was conducted using R. Results: Social structural disadvantages have little effect on the stress of caregiving. However, women experience greater subjective burden and greater depressive symptoms. The most important objective stressor is the care recipient's behavior problems, but its effects are mostly explained by subjective burden. Subjective burden tends to deplete caregivers’ informal psychosocial resources, but this does not explain why subjective burden is the most important determinant of depressive symptoms. Informal psychosocial resources do not play an important role in reducing the impact of caregiving stress on depressive symptoms. Discussion: This study suggests that without a full understanding of the effects of the burden of caregiving, any interventions or preventive actions will be of limited utility. Researchers and policymakers should consider the utility of providing tangible services to offset the negative impact of caregiving
