Background: One in five individuals in the United States provides care and support to ill, disabled, and aging family members in the home, leading to feelings of burden, stress, and poor health and well-being. Social support represents an important buffer for family caregivers that allows them to feel less isolated and more positive about their caregiving role. Methods: This sequential mixed-methods study aimed to examine the effect of the COVID-19 pandemic on family caregivers’ social connections.
