SF-36量表评价胸外科住院患者生活质量的信度和效度

目的 评价SF-36量表用于特定区域医学中心胸外科住院患者生活质量的信度和效度，以帮助该群体治疗和护理计划的制定。 方法 选取在2012年3～5月期间就诊于华西医院胸外科的患者95例，其中有效问卷94例，男68例、女26例，平均年龄 （62.0±13.0） 岁，术前诊断：肺鳞癌8例，肺腺癌6例，肺小细胞癌1例，食管癌12例，不明性质肺肿块67例。术后诊断：肺鳞癌39例，肺腺癌28例，肺小细胞癌8例，食管癌12例，肺结核3例，肺炎性假瘤4例。以SF-36量表中文版作为生活质量评价工具，以Cronbach＇s α系数和分半信度评价其信度，因子分析评价其效度。 结果 SF-36量表测量的各维度Cronbach＇s α系数为生理机能 （PF） 0.873，生理职能 （RP） 0.859，躯体疼痛 （BP） 0.888，一般健康状况 （GH） 0.721，精力 （VT） 0.899，社会职能 （SF） 0.852，情感职能 （RE） 0.872，精神健康 （MH） 0.598，分半信度系数为生理机能 （PF） 0.725，生理职能 （RP） 0.784，躯体疼痛 （BP） 0.789，一般健康状况 （GH） 0.758，精力 （VT） 0.749，社会职能 （SF） 0.745，情感职能 （RE） 0.740，精神健康 （MH） 0.426，结构效度检验共提取9个公因子，基本反映了量表的8个维度，与量表的结构构思基本相符。 结论 SF-36量表用于评价胸外科住院患者生活质量具有可靠的信度和效度。

Reliability and Validity of SF-36 Scale for Evaluating Quality of Life of Thoracic Surgery Patients

Objective To investigate the reliability and validity of Short-Form 36 Health Survey Scale （SF-36） for evaluating quality of life （QOL） of thoracic surgery patients in a specific regional medical center,and improve care and nursing plan for these patients. Methods Ninety-five patients who were admitted in Department of Thoracic Surgery of West China Hospital from March to May 2012 were enrolled in this study. Ninety-four patients finished a valid questionnairestudy including 68 male and 26 female patients with their average age of 62.0±13.0 years. Preoperative diagnosis was squa-mous cell lung cancer in 8 patients,lung adenocarcinoma in 6 patients,small cell lung cancer in 1 patient,esophageal cancerin 12 patients and undefined lung mass in 67 patients. Postoperative diagnosis was squamous cell lung cancer in 39 patients,lung adenocarcinoma in 28 patients,small cell lung cancer in 8 patients,esophageal cancer in 12 patients,pulmonary tuber-culosis in 3 patients and inflammatory pseudo-tumor in 4 patients. Chinese edition of SF-36 was used to evaluate patients’ QOL. Cronbach’s coefficients （α） and split-half reliability were used to assess its reliability. Its validity was assessed throughfactor analysis. Results Cronbach’s coefficients （α） of SF-36 were as followed：Physical Functioning （PF） 0.721,Role-Physical （RP） 0.859,General Health （GH） 0.721,Vitality （VT） 0.899,Social Functioning （SF） 0.852,Role-Emotional （RE） 0.872,and Mental Health （MH） 0.598. Split-half reliability of each part was PF 0.725,RP 0.784,GH 0.758,VT 0.749,SF 0.745,RE 0.740,and MH 0.426. Nine principal components were extracted by factor analysis and generally reflected the 8 dimensions of SF-36,which was correspondent to the SF-36 structure. Conclusion SF-36 scale can be used to measure QOL of thoracic surgery patients with good reliability and validity.
