In the present study, the reliability and construct validity of the Japanese version of the Chalder Fatigue Scale was evaluated as a measure of severity of fatigue among young students in Japan. A healthy group comprised 27 Grade 6 primary school students and 28 Grade 1 junior high school students. The severely fatigued group were hospital outpatients with childhood chronic fatigue syndrome (n = 21). Principal components analysis with varimax rotation identified 4 factors which accounted for 63.2% of the total variance, as in the original English version. Internal consistency (Cronbach coefficient alpha) was .73, and test-retest reliability measured using Spearman rank correlation coefficient was .55. Scale scores of the healthy subjects were lower than those of the patients with childhood chronic fatigue syndrome. The reliability (alpha) and construct validity of the Japanese version of the scale among healthy students in Japan were satisfactory for research studies among healthy school students.
在本研究中，对日语版查尔德疲劳量表的信度和结构效度进行了评估，以衡量日本年轻学生的疲劳严重程度。健康组包括27名小学六年级学生和28名初中一年级学生。严重疲劳组为患有儿童慢性疲劳综合征的医院门诊患者（n = 21）。采用方差最大化旋转的主成分分析确定了4个因素，这些因素占总方差的63.2%，与原始英文版相同。内部一致性（克朗巴赫系数α）为0.73，使用斯皮尔曼等级相关系数测量的重测信度为0.55。健康受试者的量表得分低于患有儿童慢性疲劳综合征的患者。日语版量表在日本健康学生中的信度（α）和结构效度对于健康在校学生的研究来说是令人满意的。
