A 3-Item Screening Scale for Caregiver Burden in Dementia Caregiving: Scale Development and Score Mapping to the 22-Item Zarit Burden Interview

Brief screening scales for caregiver burden are much needed in routine dementia services to efficiently identify caregivers of persons with dementia (PWD) for further intervention. Although the 22-item Zarit Burden Interview (ZBI) is often used, its available screening versions have not performed as well as the full version in distinguishing significant burden. We developed a brief screening scale that is valid and comparable to ZBI in distinguishing caregiver burden.
