改善肺疾病患者之日常生活功能是現今胸腔科醫療的主要目標。本研究目的旨在探討慢性阻塞性肺疾病患者憂鬱及日常生活功能之概況，進而瞭解其二者之間的相關性，以提供醫護人員參考，規劃身心層面之醫護措施。本研究採立意取樣方式，以北部某醫學中心胸腔科住院病患 120 人為對象，進行調查性、描述性的研究。 研究工具乃參照文獻採自擬的憂鬱量表及Weaver和Narsavage（ 1989 ）所發展的日常生活功能量表，研究結果發現：研究對象平均年齡為 66.4 歲，65.8 ％的個案有憂鬱情形， 且患者愈憂鬱其日常生活功能障礙度愈高，二者具有強相關性。從本研究結果可知，日常生活功能並非只受疾病病理及生理變化的影響，也受心理因素影響，臨床上，上述患者之治療或復健，若能考慮其心理狀況、日常生活功能等狀況及彼此關係，有助於提供更佳照護予慢性肺疾病患者，使其日常生活功能之障礙度達最低程度。

　　　　　The purpose of this study was to investigate the relationship betweendepression and functional capacity in 120 patients with chronic obstructivepulmonary disease (COPD). The researcher interviewed COPD patients in Chang GungHospital in Taipei City. Purposive sampling data was collected through face toface interviews using a self-developed instrument. The findings showed that themean age of the patients was 66.4; 65.8% of the patients had significantdepression. There was significant correlation between depression and pulmonaryfunctional status. The more depressed patients were, the worse their functionalcapacity. The results of this study provide a picture of functional capacity anddepression of COPD patients. We recommend that health care providers useavailable measuring tools in clinical practice to assess depression andfunctional capacity of patients with chronic obstructive pulmonary disease.
