We performed this cross-sectional study with 72 chronic obstructive pulmonary disease (COPD) patients and their family caregivers to analyze relationship of physical and psychological health status between COPD patients and caregivers. Most caregivers were female (100%). Caregiver depression and burden were significantly associated with caregiving hours. In path analysis, the higher the patient's social support, the higher the patient's self-efficacy. The higher the patient's self-efficacy, the lower the care burden of the caregiver.
