Burden, family functioning, and psychological health of older caregivers of older adults: a path analysis

Objectives: To evaluate an explanatory model of direct and indirect associations regarding the psychological health of older caregivers of functionally dependent older adults. Methods: This is a cross-sectional study performed with older caregivers recruited in contexts of outpatient and home care. We collected information on sociodemographic characteristics, duration of caregiving, physical and cognitive function indicators of the older care recipients, perceived burden, family functioning, and psychological health measures (psychological need satisfaction and depressive symptoms). Results: We evaluated 133 caregivers (76% female, 69.5 ± 6.98 years). Variables that were significantly correlated with psychological health were selected to form an association model to be tested by structural equation modeling via path analysis. Depressive symptom variability was best explained by this model. Caregiver burden remained in the model as a mediator of indirect associations between physical function for instrumental activities of daily living and indicators of family functioning and psychological health. Three associative paths between caregiver burden and depressive symptoms were found — one of them was direct and the other two were mediated whether by family functioning or by the level of psychological need satisfaction. Conclusion: Depressive symptoms were the psychological health indicator best explained by the model involving instrumental functional demands that generate burden. Clinical consequences suggested by the model indicate interventions aimed at family functioning and opportunities of psychological need satisfaction as strategies for promoting caregivers’ psychological health.
