title: The relationship of perceived self-efficacy to quality of life in chronic obstructive pulmonary disease.
abstract: From a biomedical perspective, variations in the quality of life of chronic obstructive pulmonary disease (COPD) patients may be attributed to changes in pulmonary function; thus, an increase in lung function should be correlated with an increased score on a health-related quality-of-life measure. However, inconsistent results regarding correlations between various measures of pulmonary function and quality of life have been reported in the literature. The authors evaluated a social cognitive model of quality of life among persons with COPD by analyzing relationships among biomedical measures, self-efficacy measures, and quality-of-life measures in a recursive path model. Path analysis results indicated that the association of pulmonary function and symptoms with quality of life was mediated by perceived self-efficacy for functional activities.
