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.
从生物医学角度来看，慢性阻塞性肺疾病（COPD）患者生活质量的变化可能归因于肺功能的改变；因此，肺功能的提高应与健康相关生活质量测量得分的增加相关。然而，文献中报道了关于各种肺功能测量与生活质量之间相关性的不一致结果。作者通过在递归路径模型中分析生物医学测量、自我效能测量和生活质量测量之间的关系，评估了COPD患者生活质量的社会认知模型。路径分析结果表明，肺功能和症状与生活质量之间的关联是由对功能活动的自我效能感介导的。
