Predictors of Spiritual Well-Being in Family Caregivers for Individuals with Parkinson's Disease.

Background

Parkinson's disease (PD) is a common neurodegenerative illness that causes disability through both motor and nonmotor symptoms. Family caregivers provide substantial care to persons living with PD, often at great personal cost. While spiritual well-being and spirituality have been suggested to promote resiliency in caregivers of persons living with cancer and dementia, this issue has not been explored in PD.

Objective

The aim of this study was to identify predictors of spiritual well-being in PD patients' caregivers.

Design

A cross-sectional analysis was performed. Our primary outcome measure, the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp), was measured in caregivers alongside measures of patient quality of life, symptom burden, global function, grief, and spiritual well-being and caregiver mood, burden, and perceptions of patient quality of life. Univariate correlation and multiple regression were used to determine associations between predictor variables and caregiver FACIT-Sp. Setting/Subjects: PD patient/caregiver dyads were recruited through three academic medical centers in the United States and Canada and regional community support groups.

Results

We recruited 183 dyads. Patient faith, symptom burden, health-related quality of life, depression, motor function, and grief were significant predictors of caregiver spiritual well-being. Predictive caregiver factors included caregiver depression and anxiety. These factors remained significant in combined models, suggesting that both patient and caregiver factors make independent contributions to caregiver spiritual well-being.

Conclusions

The present study suggests that both patient and caregiver factors are associated with spiritual well-being in PD. Further study is needed to understand the causal relationship of these factors and whether interventions to support caregiver spiritual well-being improve outcomes for caregivers or patients.
