SF-36用于肺结核的信度、效度及敏感性评价

Evaluation on SF-36 to assess quality of life of patients with pulmonary tubercolosis

目的 评价中文版SF - 36量表用于肺结核 (PTB)病人的生命质量测量的信度、效度、敏感性。方法 用自行研制的中文版SF - 36量表对肺结核病人及对照进行测量。采用Cronchbach’sα评价量表的信度 ,因子分析评价量表的效度 ,用配对t检验比较患者组和对照组的评分来评价量表的敏感性。结果 对于病人组和对照组 ,SF - 36量表效度 (因子分析聚合为 2个公因子 )、信度 (Cronchbach’sα >0 7)较好。肺结核病人各项得分均低于对照组 ,说明量表的敏感性较高。结论 中文版SF - 36量表是测量肺结核病人的生命质量的有效量表 ,但量表中个别词句的翻译仍须改动 ,并且有必要进行更大样本的调查 ,建立中国人的生命质量正常值标准 。

Objective To evaluate the reliability,validity and sensitivity of Chinese version SF-36 to assess the quality of life of PTB patients.Methods Subjects were interviewed by using Chinese version of SF-36.Validity of the scores was tested by factor analysis and reliability coefficients were estimated by Cronchbach's a with 0.7 as a standard.Sensitivity was evaluated by comparison of PTB cases and controls.Results Scores of SF-36 in both groups were valid (The patterns of correlations between 8 scales of SF-36 and rotated two factors supported it) with reliability coefficients as estimated by Cronchbach's a above 0.7.Scores of SF-36 in both groups had high sensitivity (all scales of TB patients were lower than that of the control).Conclusion Chinese version of SF-36 was a valid and reliable tool for assessment of quality of life,and cultural diversity might require slight modifications of SF-36.There was a need of large scale general health survey to produce normative data for Chinese population.
