Chronic obstructive pulmonary disease (COPD) is a progressive, irreversible disease and is the third leading cause of mortality. Past studies suggest that individuals with COPD have poorer quality of life and decreased psychological well-being compared to the general population. In addition, previous studies indicate that negative illness perceptions among patients with COPD are associated with psychological distress and poor quality of life. However, no prior studies have examined the relationship of caregiver illness perceptions to COPD patient outcomes. This cross-sectional study evaluated the relationship of illness perceptions with quality of life and psychological functioning among patients with COPD and extended the literature by examining the moderating effects of caregiver perceptions in the relationship of patient illness perceptions and patient outcomes. In addition, the current study examined relationship of caregiver illness perceptions and caregiver outcomes. The current study included 55 patients with COPD (85.5% Caucasian, 52.7% male, mean age = 63.5 years, mean FEV1 % predicted = 72.5%) and 36 caregivers (83.3% Caucasian, 72.2%, female, mean age = 58.1). Pearson correlations and hierarchical regression analyses were the primary modes of data analysis. Correlational analyses indicated that patient illness perceptions were associated with patient quality of life and psychological well-being, but not with functional capacity or disease severity. Caregiver perceptions of consequences were associated with poorer physical quality of life and increased burden. Hierarchical regression analysis of patient anxiety revealed an interaction between patient perceived consequences and caregiver perceived consequences. Thus, when caregiver perception of consequences for the patient and self are low, patient perceived consequences is associated with greater anxiety. Regression analyses revealed interactions of patient emotional representation (i.e., negative response to illness.) with caregiver emotional representation for patient physical quality of life and illness-specific quality of life. These interactions indicate that in the context of higher emotional representation among caregivers, emotional representation for patients is associated with poorer quality of life. Results of this study suggest that negative illness perceptions, specifically perceived consequences and emotional representation are associated with poorer patient outcomes. Furthermore, caregiver perceptions of consequences and emotional representation moderated the relationship of patient illness perceptions and patient quality of life and psychological well-being. Patient well-being may be particularly poor in the context of congruent beliefs between patient and caregiver regarding emotional representation. Results indicate the importance of assessing illness perceptions among patients as well as among caregivers. Identifying patients and caregivers with negative illness perceptions could facilitate interventions directed toward improving quality of life among patients with COPD.
