The aims of the present study were to develop and validate the Japanese version of the checklist individual strength questionnaire (CIS) which is used to measure prolonged fatigue not only in the general population but also in the working population. We obtained permission to use CIS from its author and translated the questionnaire into Japanese. Then, the Japanese version of the questionnaire was translated back into English by a bilingual person. The author of the original version agreed that the back-translated version was conceptually and linguistically equivalent to the original CIS. To validate CIS, 399 workers (66.7% were men) from different companies answered the Japanese version of the CIS (CIS-J), Maslach burnout inventory-general survey (MBI-GS), Beck Depression Inventory-II (BDI-II), visual analogue scale (VAS) questionnaires for subjective fatigue, number of overtime hours and number of hours of sleep. Cronbach's alpha for the total CIS-J score was 0.91. The test-retest reliability assessed with an intra-class correlation coefficient was 0.82. Although confirmatory factor analysis did not show an ideal model fit, the correlation coefficients between the total CIS score and the MBI-GS exhaustion score, the BDI-II score and the VAS score were 0.58 (p<0.01), 0.66 (p<0.01) and 0.63 (p<0.01), respectively. The less workers slept and the longer they worked, the higher their total CIS score became. CIS-J showed good reliability and acceptable validity in the working population. Thus, it could be useful for studying fatigue among Japanese working populations.
本研究的目的是开发并验证日本版的清单个人力量问卷（CIS），该问卷不仅用于测量普通人群，还用于测量工作人群中的长期疲劳。我们获得了该问卷作者的使用许可，并将其翻译成日语。然后，由一位双语人员将日语版问卷再翻译回英语。原版作者认可回译版在概念和语言上与原始CIS等效。为了验证CIS，来自不同公司的399名员工（66.7%为男性）回答了日本版的CIS（CIS-J）、马氏倦怠量表通用版（MBI-GS）、贝克抑郁量表第二版（BDI-II）、主观疲劳视觉模拟量表（VAS）问卷、加班时长问卷和睡眠时间问卷。CIS-J总分的克朗巴哈系数为0.91。用组内相关系数评估的重测信度为0.82。尽管验证性因素分析未显示出理想的模型拟合，但CIS总分与MBI-GS倦怠得分、BDI-II得分和VAS得分之间的相关系数分别为0.58（p<0.01）、0.66（p<0.01）和0.63（p<0.01）。员工睡眠越少、工作时间越长，其CIS总分就越高。CIS-J在工作人群中显示出良好的信度和可接受的效度。因此，它可能有助于研究日本工作人群中的疲劳情况。
