癌因性疲乏自评量表的编制及信效度检验

Establishment of self rating scale for cancer related fatigue and its reliability and validity test

目的研制一种经过标准化、简便可行的符合我国文化背景和我国肿瘤患者疲乏特征的疲乏测评工具,并进行信效度检验。方法采用深度访谈、文献回顾和德尔菲法形成初期量表,经过预测试、大样本测试形成正式量表。采用项目分析、探索性因子分析、验证性因子分析、相关性分析、内部一致性检验、折半信度分析、内容效度等对量表进行评价。结果形成的癌因性疲乏自评量表包括4个维度,15个条目,累积方差贡献率为71.304%;验证性因子分析结果为χ2/df=1.956,RMSEA=0.064,CFI=0.961,GFI=0.912,AGFI=0.874,IFI=0.962;Cronbach'α为0.92,折半系数为0.850;内容效度为0.903;较标效度为0.717。结论量表具有良好的信度和效度,可以作为肿瘤患者疲乏状况的测量工具。

Objective To develop a scale for measuring cancer related fatigue and to test its reliability and validi- ty. Method Depth interview, literature review and two round Delphi consultation were performed to identify items of the questionnaire. The reliability and validity was tested among 357 cancer patients. Result The cancer related fatu- gue scale consisted of 15 items and four factors. The cumulative contribution of variance was 71. 304%o. Confirmato- ry factor analysis showed moderate model fitting ： Zz/df~ 1. 956,RMSEA = 0. 064, CFI= O. 961,GFI=0. 912 ,AGFI =0. 874,IFI=0. 962. The Cronbachs alpha of the total scale was 0.92. the content validity index was 0. 903 and ri- teflon validity was 0. 717. Conclusion The cancer related fatigue scale has been proved to be reliable and valid. It can be used to assess the fatigue level of cancer patients.
