前言：近年来，许多研究强调了评估慢性阻塞性肺疾病(COPD)患者健康状况的重要性。本研究旨在检验土耳其版圣乔治呼吸问卷(SGRQ)的效度和信度。材料和方法：研究在土耳其的七个中心进行。321例慢性阻塞性肺疾病患者(年龄40-75岁)纳入研究。对患者进行呼吸困难、咳嗽、咳痰、呼吸困难、SGRQ、慢性阻塞性肺疾病评估试验(CAT)和简明健康状况调查(SF-36)的土耳其文版调查。结果：平均年龄为62.4±8.9岁，平均FEV1为51.9±19.2%。内部一致性系数(Cronbachα)为0.8815。初测总分与两周后总分呈高度显著相关(r=0.9，p<；0.0001)。总分和各分量表的效度检验结果表明，总分与CAT的相关系数为0.782(p<；0.0001)，SGRQ与SF_(36)的相关系数为-0.481-0.819(p&t；0.0001)。结论：SGRQ土耳其语版是一种可靠、有效的COPD患者临床评估工具。
Introduction: The importance of the evaluation of health status in chronic obstructive pulmonary disease (COPD) is recently highlighted in many studies. In this study, we aimed to test the validity and reliability of the Turkish version of St. George Respiratory Questionnaire (SGRQ).Materials and Methods: The study was conducted in seven centers in Turkey. Three hundred and twenty one COPD patients (40-75 years) were included to the study. Turkish versions of breathlessness, Cough, and Sputum Scale (BCSS), mMRC (Modified Medical Research Council) dyspnea scale, SGRQ, COPD assessment test (CAT) and Short Form Health Survey (SF-36) were carried out to the patients. The statistical analysis of SGRQ was performed by using the coefficient of internal consistency, discriminative analysis for different stages and the correlation with the other scales.Results: The mean age was 62.4 +/- 8.9 years and the mean FEV1 was 51.9 +/- 19.2% pred. The coefficient of internal consistency (Cronbach alpha) was 0.8815. The correlation between the total score measured initially and that obtained two weeks later was found to be highly significant (r= 0.90, p< 0.0001). According the results of validation of both total score and the components of SGRQ, the correlation between the total score of SGRQ and CAT was 0.782 (p< 0.0001), SGRQ and SF36 was between -0.481 ile -0.819 (p< 0.0001). The total and component scores were able to discriminate different disease stages and a significant correlation was found to be with pulmonary function tests.Conclusion: SGRQ Turkish version is a reliable and valid assessment tool for COPD patients in clinical practice.
