Background: Caring for people with dementia (PWD) is stressful and poses many life challenges for the family caregivers. Interventions targeting the stress and psychological well-being of the caregivers have been proposed but the sustainable effects and efficacies of these interventions vary considerably. Mindfulness-based cognitive therapy (MBCT) has been shown to be effective at reducing stress in several populations. However, limited research on the effects of MBCT in family caregivers of PWD has been conducted.
