Health-Related Quality of Life and Self-Efficacy of Managing Behavior Problems for Family Caregivers of Vascular Dementia and Alzheimer's Disease Patients

Abstract

Background: Little is known about the differences in patients' behavioral problems and health outcomes of family caregivers of patients with vascular dementia (VaD) and Alzheimer's disease (AD). Methods: A secondary analysis of baseline data on a subsample of caregiver-dementia patient dyads in a randomized clinical trial. Results: Family caregivers of VaD patients reported higher self-efficacy than caregivers of AD patients in handling verbally nonaggressive and verbally aggressive behaviors. Caregivers of VaD patients had poorer health-related quality of life (HRQoL) than caregivers of AD patients considering role disability due to physical health problems, bodily pain, social function, and physical component summary. Greater self-efficacy was associated with better mental health-related outcomes for family caregivers of VaD patients, and better self-care ability of VaD patients was associated with better caregiver mental health-related outcomes. Caring for a patient with more severe dementia predicted poor physical health-related outcomes in role disability due to physical health problems, but better overall mental health (mental component summary) for caregivers. Conclusion: This study is the first to examine and compare the behavioral problems of AD and VaD patients in a Chinese population, along with their family caregivers' self-efficacy and health outcomes. Family caregivers of patients with VaD might warrant specific attention to their HRQoL, with interventions developed to enhance their self-efficacy.
