Caregiver Burden among Caregivers of Older Adults with Alzheimer’s Disease Impairs their Quality of Life: A Cross-sectional Study in Brazil
##plugins.themes.bootstrap3.article.main##
Abstract
Introduction. The role of caregivers of older adults with Alzheimer’s disease is crucial but often challenging.
Objective. To determine whether the increased burden of care among caregivers of older adults with Alzheimer’s disease negatively impacts their perceived quality of life.
Method. This is a cross-sectional study of 126 caregivers using the Zarit Caregiver Burden Interview and WHOQOL-Bref. Data analysis included the Kolmogorov-Smirnov test, skewness and kurtosis coefficients, bootstrap procedures, Pearson correlation, simple linear regression analysis, Pearson’s Chi-square test, and One-Way ANOVA together with Tukey’s Post-Hoc test (p < .05).
Results. The burden level explained a significant degree of caregivers’ perceived quality of life (p < .01), with a significant negative prediction across all quality of life domains (β = -.48 to -.62).
Discussion and conclusion. Higher burden levels compromise caregivers’ perceived quality of life.
