We aimed to assess the influence of anxiety and depression on the physical and mental quality of life (QoL) in patient with chronic obstructive pulmonary disease (COPD) and caregiver dyads, detect the simultaneous effect of anxiety and depression of each partner on the other's QoL and determine the dyadic patterns. ⋯ The results suggest that caregivers' psychological distress influences caregivers' mental QoL and patients' physical QoL. Therefore, health-care professionals should assess and treat anxiety and depression in both members of the COPD dyad to improve their QoL.
