This paper aimed to explore factors associated with burden of care among informal caregivers who had made housing decisions on behalf of a cognitively impaired older person. Factors significantly associated with higher caregiver burden were being female, being the spouses and children of the person cared for; and the perception that a joint decision making process had occurred - caregivers may find it intimidating to partake in collective decision-making with a team of professionals. These findings will help design interventions to prevent and/or reduce caregivers’ burden of care.
