癌症疲乏量表中文版的信效度

Reliability and validity of the Chinese version of Cancer Fatigue Scale

目的:分析癌症疲乏量表(CFS)中文版的信度和效度。方法:通过正向翻译、综合、回译、专家评议和预调查5个步骤对CFS进行跨文化调适,修订成中文版。采用方便取样,对187名癌症患者施测CFS中文版进行项目分析、内部一致性检验、探索性因素分析和癌因性疲乏总体状况分析。1周后对其中42名患者重测CFS中文版,评价重测信度。结果:量表共15个条目,包括躯体、情感和认知3个维度。各维度与总量表的内部一致性Cronbachα系数在0.63～0.86,重测信度为0.55～0.77。探索性因素分析得到3个因素,共解释了59.04%的累计方差贡献率,各条目载荷均>0.40。结论:癌症疲乏量表中文版具有较好的信度和效度,符合心理测量学要求。

Objectives： To evaluate the reliability and validity of the Chinese version of Cancer Fatigue Scale （CFS）. Methods： After the translation, synthesis, back translation, expert committee review, and pretesting processes, the CFS was revised into a Chinese version （CFS-C）. Totally 200 Chinese cancer patients completed CFS-C initally and 42 of them were investigated a week later to evaluate the test-retest reliability. Results： The CFS-C comprised 15 items and reflected 3 dimentions of physical, emotional and cognitive fatigue. The internal consistency reliability evaluated by Cronbach＇a was 0.63 -0. 86 for the three subscales and the whole scale. The test-retest reliability was from 0. 55 to 0. 77. Factor analysis displayed good construction of the CFS-C. Conclusion： The Chinese version of Cancer Fatigue Scale （CFS） has good reliability and validity, meeting psychometric criteria.
