Reliability and validity of the Japanese version of the Chalder Fatigue Scale among youth in Japan. | LitMetric

AI Article Synopsis

  • The study assessed the reliability and validity of the Japanese version of the Chalder Fatigue Scale to measure fatigue in young Japanese students.
  • It involved 55 healthy students and 21 students diagnosed with childhood chronic fatigue syndrome, identifying four factors that explained over 63% of the variance in fatigue levels.
  • The scale showed satisfactory internal consistency (alpha = .73) and moderate test-retest reliability (correlation = .55), indicating it is a valid tool for research among healthy school students.

Article Abstract

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.
