Heart failure is a serious and complex chronic illness and family caregivers often assist these individuals in performing self-care. Unsurprisingly, caregivers often are overwhelmed by daily activities associated with heart failure management and frequently have depressive symptoms. This study examined predictors (i.e., sociodemographic and clinical characteristics, social support, social problem-solving, family functioning, and objective and subjective burden) of depressive symptoms in 530 informal caregivers of individuals with heart failure in a large cross-sectional, descriptive study in the community. Younger caregivers who provided care for longer periods of time, lived in rural areas, and had less social support and lower problem-solving skills were more likely to have depressive symptoms. These findings emphasize the need for further studies to develop dynamic and innovative approaches that incorporate multiple components to lessen caregiving challenges. Social support and problem-solving skills training may be useful components to lessen depressive symptoms in these younger, rural caregivers.
