肺移植特异性生活质量量表的汉化及信效度检验

Validation of Chinese version of the Lung Transplant Quality of Life survey for lung transplant recipients

目的对肺移植特异性生活质量量表(The Lung Transplant Quality of Life Survey,LT-QOL)进行汉化,并在肺移植术后患者中检验其信效度。方法通过正译、回译、文化调试和预调查对LT-QOL进行汉化。通过2轮专家咨询进行内容效度评价。2019年11月—2021年3月,选取于无锡市某三级甲等医院肺移植门诊就诊的308例肺移植术后患者进行调查,评价量表的信效度。结果中文版LT-QOL包括3个维度、11个方面、40个条目。量表水平的内容效度指数为0.912,条目水平的内容效度指数为0.781~1.000。探索性因子分析提取11个公因子,累计方差贡献率为71.424%。总量表的Cronbach’sα系数为0.947,各公因子的Cronbach’sα系数为0.710~0.929;总量表的重测信度为0.870,各公因子的重测信度为0.726~0.894。结论中文版LT-QOL具有良好的信效度,适合中国文化背景下肺移植术后患者生活质量的评估。

Objective To test the reliability and validity of the Chinese version of the Lung Transplant Quality of Life survey(LT-QOL)in patients after lung transplantation.Methods We sinicized the LT-QOL following the forward translation,back translation,cultural adaptation and pre-survey.Evaluation of content effectiveness was conducted through 2 rounds of expert consultations.From November 2019 to March 2021,308 post-lung transplant patients who were admitted to a lung transplant clinic of a tertiary A hospital in Wuxi were selected to investigate for the test of the reliability and validity of the scale.Results The Chinese version of LT-QOL includes 3 dimensions and 11 aspects with a total of 40 items.The content validity index of the total scale is 0.912,and the content validity index of each item is between 0.781 and 1.Exploratory factor analysis resulted in an 11-factor structure,explaining 71.424%of the total variance.The Cronbach’sαcoefficient for the total LT-QOL score was 0.947,and 0.710~0.929 for every common factor.The retest reliability for the total LT-QOL score was 0.870,and 0.726~0.894 for every common factor.Conclusion The Chinese version of LT-QOL appears to possess adequate validity,retest reliability and internal consistency.The newly translated Chinese version of LT-QOL can be used to assess the quality of life of lung transplant recipients in China.
