Health-related quality of life in individuals with chronic obstructive pulmonary disease

Background -related quality of life (HRQOL) is an individual’s perception of physical and mental health. ive jective of this study was to examine the relationships between symptoms and HRQOL in individuals with chronic obstructive pulmonary disease (COPD), using a modification of a HRQOL model in COPD. elational descriptive design was used to examine the relationships between symptoms and HRQOL in individuals with COPD. ts enience sample of 58 subjects with a medical diagnosis of COPD, specifically chronic bronchitis or emphysema, was evaluated. es rtical Visual Analogue Scale, Baseline Dyspnea Index, Bronchitis-Emphysema Symptom Checklist, Positive and Negative Affect Scales, Pulmonary Functional Status and Dyspnea Questionnaire, and Medical Outcome Study Short Form-36 Health Survey were used. s les that affected the physical health component of HRQOL included breathlessness, physical impairment, and reduced activities of daily living (adjusted R2 = .52, P < .001), and variables that affected the mental health component of HRQOL were breathlessness, hopelessness and anxiety, and negative affective trait (adjusted R2 = .58, P < .001). sions lessness, physical impairment, reduced activities of daily living, hopelessness and anxiety, and negative affective trait seem to contribute to physical and mental components of HRQOL in individuals with COPD.
