醫學中心的胸腔內科門診部取得100位診斷為慢性阻塞性肺部疾病的病患。收案期間為97年3月1日至87年5月31日。本研究以SPSS〈社會科學的統計軟體〉做資料分析。聖喬治呼吸問卷的分數與病患的第一秒吐氣量(FEV1) (r=-.37 ~ -.44)以及病患的六分鐘的步行距離(r=-.33~ -.48)呈現負相關，聖喬治呼吸問卷的分數與柏格呼吸困難量表(r=.41~.62)則呈現中度的=正相關；而聖喬治呼吸問卷的總分數與簡版的疾病衝擊量表的總分的相關係數為.69，聖喬治呼吸問卷的活動部分和簡版的疾病衝擊量表總分的相關性為0.72，而聖喬治呼吸問卷的衝擊部分和簡版的疾病衝擊量表總分的相關性為0.64。以上r值皆達到統計上之顯著水準(p<0.01)。聖喬治呼吸問卷在本研究對象的內在一致性是以Cronbach’s α來評量，「症狀」0.76、「活動」0.79、「衝擊」0.86，而「總分」的內在一致性是0.92。簡版的疾病衝擊量表的內在一致性是0.82。這些α值都在0.70以上而且達到可接受的範圍(Nunnally, 1978)。簡版的疾病衝擊量表中的「心理上的自主性與溝通」與「情緒的穩定性」，和無人勾選的「身體的自主性」等項目的題目不適用於本研究個案。基於這些研究結果，顯示聖喬治呼吸問卷可用在台灣慢性阻塞性肺部疾病的病人，來測量其與疾病相關的生活品質。

Treatment of diseases causing COPD is largely directed toward relief of symptoms and improvement in the quality of life. Given the increasing interest in multinational clinical studies measuring perceived health status, the St. George's Respiratory Questionnaire (SGRQ) and the short form of the Sickness Impact Profile (SIP68) were chosen for evaluating Taiwanese C~PO patients. In this study, a cross-sectional correlational survey design was used. A convenience sample of 100 patients diagnosed with COPD, as defined by the American Thoracic Society, was recruited from a pulmonary clinic of a university hospital in Taipei, Taiwan. The sample was recruited from March 1 to May 31, 1998. The SPSS (Statistical Program for the Social Sciences) for Windows was used for the analysis of data. Results: FEV, showed negative correlations with the SGRQ total score, its three sections, and the SIP68 (r=-.37 to -.44). The SGRQ scores and the SIP68 were negatively correlated with the 6-minute walk distance (r=-.33 to -.48). Dyspnea ratings on the Borg scale were moderately positively correlated with both the SGRQ and the SIP68 scores. The correlation between the SGRQ total score and the SIP68 total score was .69 (p <.01) . Internal consistency of each section score of the SGRQ was assessed by Cronbach's coefficient, which was .76 for the Symptoms section, .79 for the Activity section, .86 for the Impacts section, and .92 for the total SGRQ. The Cronbach's coefficient of the SIP68 was .82 in this sample. These values were greater than .70 and reached an acceptable level. The findings of these procedures suggest that the SGRQ can be used to measure health-related quality of life in Chinese COPD patients.
