中文版气管切开术后患者生活质量量表的言效度检验

目的 引进气管切开术后长期置管患者生活质量量表(TQOL),并检验信效度.方法 按照Brislin跨文化翻译原则对TQOL进行汉化及文化调适,使用中文版TQOL量袁调查153例气管切开术后患者的生活质量,分析其信效和效度.结果 中文版TQOL保留22个条目,因子分析共提取生理状况、躯体功能状况、社会/家庭状况、满意程度4个公因子,累计贡献率达68.45％.量表内容效度指数为0.920,Cronbach's α系数为0.907,各因子Cronbach' s α系数为0.824～0.912,Guttmann折半系数为0.925(均P＜0.01).结论 中文版TQOL具有良好的信效度,适合中国文化背景下气管切开术后长期置管患者生活质量的测量.

Reliability and validity test of Chinese Tracheotomy-specific Quality of Life questionnaire

Objective To translate the Tracheotomy-specific Quality of Life questionnaire (TQOL) into Chinese,and to test its reliability and validity.Methods Following the equivalence model and the Brislin's principles of translation,the TQOL was translated into Chinese and adapted according to Chinese culture.A total of 153 patients after tracheotomies were investigated using the Chinese version of TQOL,then its reliability and validity were analyzed.Results The Chinese version TQOL included 22 items,four factors (physiological status,body function,social/family status and satisfaction degree) were extracted by factor analysis,which could explain 68.45％ of the total variance.The content validity index was 0.920,the Cronbach's a was 0.907 for the question naire,and the Cronbach's α ranged from 0.824 to 0.912 for each factor,the Guttmann-split half reliability was 0.925(P＜0.01 for all).Conclusion The Chinese version TQOL has good reliability and validity,and it is suitable to measure quality of life for Chinese patients after tracheotomies.
