Predictors of Burden for Caregivers of Patients with Parkinsonʼs Disease

Abstract

Parkinson's disease (PD) is a chronic, progressive neurological disease that affects an estimated 1 million Americans each year. Its progressive nature leads to increased burden for the caregiver. This study explored factors that contribute to the perception of burden in caregivers of individuals with PD using a cross-sectional design. The sample consisted of 41 caregivers who were married to or cohabitating with individuals with PD. Questionnaires were mailed to spousal caregivers and returned via mail. Burden was determined by utilizing the Zarit Burden Inventory. The independent variables that were measured were activities of daily living (ADLs), perceived social support, psychological well-being, and marital satisfaction. All four factors were found to significantly predict perceived burden. Multiple regression analysis showed that ADLs and perceived social support were significant predictors of caregiver burden, accounting for 44.3% of the variance. The implication for healthcare professionals is that they should provide information on PD symptom management, thus promoting independence in performing ADLs, identifying appropriate resources to reduce caregiver burden, and using support groups.
