本研究的目的是测试一个解释模型的变量影响功能状态的慢性阻塞性肺疾病（COPD）。样本包括104例COPD患者（85例男性，19例女性;平均年龄= 65.5，SD= 7.7）。初始模型中的变量包括年龄、病程、肺功能、运动时氧饱和度下降、呼吸困难、抑郁情绪、焦虑、自尊、运动能力和功能状态。通径分析显示，运动能力（β=. 337，p=. 0007）、呼吸困难（β=. 324，p=. 0009）、抑郁情绪（β=-. 204，p=. 011)直接影响功能状态。呼吸困难（β=. 488，p<. 0001）、抑郁（β=-. 217，p=. 003）、肺功能（β=. 421，p<. 0001）通过运动能力间接影响功能状态。自尊（β=-. 492，p=. 004)焦虑（β=. 696，p<. 0001）通过抑郁情绪间接影响功能状态。这项研究的结果表明，改善COPD患者功能状态的努力应该集中在影响运动能力、呼吸困难、焦虑和抑郁情绪的干预措施上。
The purpose of this study was to test an explanatory model of variables influencing functional status in chronic obstructive pulmonary disease (COPD). The sample consisted of 104 patients with COPD (85 males, 19 females; mean age= 65.5, SD= 7.7). The variables in the initial model were age, length of illness, pulmonary function, oxygen desaturation during exercise, dyspnea, depressed mood, anxiety, self-esteem, exercise capacity, and functional status. Path analysis revealed that exercise capacity (β=. 337, p=. 0007), dyspnea (β=. 324, p=. 0009), and depressed mood (β=-. 204, p=. 011) directly influenced functional status. Dyspnea (β=. 488, p<. 0001), depression (β=-. 217, p=. 003), and pulmonary function (β=. 421, p<. 0001) indirectly influenced functional status through exercise capacity. Self-esteem (β=-. 492, p=. 004) and anxiety (β=. 696, p<. 0001) indirectly influenced functional status through depressed mood. The findings of this study suggest that efforts to improve functional status of individuals with COPD should focus on interventions that influence exercise capacity, dyspnea, anxiety, and depressed mood.
