Family Relationship Quality is Associated with Psychological Distress Dyspnea and Quality of Life in COPD

摘要

Family relationship quality predicts medical outcomes in various health conditions, including stroke, end stage renal disease, and heart failure. Family relationships also influence the onset and course of depression and anxiety disorders. Family may be particularly important in COPD given the high prevalence of depression and anxiety in COPD patients and the association of depression and anxiety with important clinical features of COPD such as dyspnea. The objective of this study was to test three hypotheses in a sample of individuals with COPD: 1) unsupportive family relationships are associated with psychological distress; 2) psychological distress is associated with dyspnea and impairment in health-related quality of life; and 3) unsupportive family relationships are indirectly associated with dyspnea and health-related quality of life via psychological distress. Cross-sectional data were collected via self-report questionnaires completed by 526 individuals with COPD. Structural equation modeling was used to test the hypotheses. All three hypotheses were supported. Unsupportive family relationships were associated with psychological distress, psychological distress was associated with dyspnea and impairment in health-related quality of life, and unsupportive family relationships were indirectly associated with dyspnea and health-related quality of life via psychological distress. If subsequent longitudinal investigations demonstrate that unsupportive family relationships do indeed lead to psychological distress among individuals with COPD, then interventions to improve family relationships of patients with COPD could lead to reductions in psychological distress and, ultimately, to improvements in dyspnea and quality of life.
