Congestive heart failure significantly compromises quality of life by contributing to severe physical, role, and social functioning impairment as well as increased psychological distress. Previous research examining quality of life in CHF patients has typically been conducted using global self-report instruments that may exceed a patient's ability to accurately recall their experiences. This investigation examines the impact of disease severity, functional status, and level of depression on daily quality of life (i.e., mean level and variability) in CHF patients during a 2-week monitoring period. Indices of quality of life included emotional and physical quality of life, social support and conflict, positive and negative mood, and coping responses. Fifty-eight patients with CHF participated in the investigation. Depressive symptoms were positively associated with a number of quality of life indices (i.e., physical and emotional quality of life, social support and conflict, mood, and coping behaviours). Left ventricular ejection fraction and functional impairment had a much weaker association with quality of life. These findings suggest that depressive symptoms may have a greater impact on quality of life in CHF patients than severity of cardiac dysfunction or functional impairment.
