Background: Managing the burden of care for patients with chronic debilitating diseases is an important issue. Herein, we assessed the burden in primary family members caring for uremic patients on maintenance peritoneal dialysis. Methods: One hundred seventy caregivers and 170 patients were recruited. Self-perceived scoring along the Zarit Caregiver Burden Scale (ZCBS), World Health Organization Five-item Well-Being Index (WHO-5), and Warwick-Edinburgh Mental Well-being Scale (WEMWBS) were determined for caregivers.
