Background: To prevent COVID-19 from spreading in long-term care facilities (LTCFs), the Dutch government took restrictive measures, including a visitor-ban in LTCFs. Objectives: This study examined the relationship between involvement of family caregivers (FCs) of people with dementia (PwD) living in LTCFs and FCs mental health during the visitor-ban, and whether this relationship was moderated by the frequency of alternative contact with PwD during the visitor-ban and FC resilience.
