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

摘要

摘要:
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, 以利于生命质量的评价。

Abstract:
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 reliabilit y 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.
