Background: A substantial number of family caregivers go through bereavement because of cancer, but little is known about the bereaved caregivers' long-term adjustment. This study aimed to document levels of bereavement outcomes (prolonged grief symptoms, intense emotional reaction to the loss, depressive symptoms, and life satisfaction) among family cancer caregivers 3-5 years post-loss and to investigate how self-rated preparedness for the patient's death predicted those bereavement outcomes.
