Informal caregivers play a crucial role in supporting persons with multiple sclerosis (MS), a neurodegenerative disease resulting in progressive worsening of physical and cognitive functioning. While research extensively showed that caregiving workload can be perceived as burdensome, little attention was devoted to the relation connecting workload and caregivers' well‐being. Building on previous literature on stress and coping, the aim of this study was to test the mediational role of coping between caregivers' tasks and well‐being.
