Fifty caregivers and 41 heart failure patients participated in a study examining the association of caregiver characteristics and the caregiving environment on caregiver burden. Using a cross-sectional design, caregivers were interviewed face-to-face using a caregiver characteristic/demographic tool designed for this study, the Centers for Epidemiological Studies Short Depression Scale, the Caregiver Reaction Assessment questionnaire, and the New York Heart Association Functional Classification Guide to obtain the caregiver's perception of patient disease severity.
