概要	The Cancer Fatigue Scale is a 15-item disease-specific self-report instrument that comprehensively assesses three dimensions of cancer-related fatigue: physical, cognitive, and emotional. Developed by Takuo Okuyama and colleagues at the Japanese Foundation for Cancer Research and published in 2000, the CFS provides a brief yet multidimensional fatigue profile suitable for both clinical practice and research, with particular strength in non-English-speaking populations where it has been extensively validated.	The Chalder Fatigue Scale is an 11-item brief self-report instrument measuring physical and mental fatigue, developed by Trudie Chalder and colleagues at St. Bartholomew's Hospital, London, in 1993. Originally designed for chronic fatigue syndrome (myalgic encephalomyelitis/ME) research, the CFS has been extensively validated across cancer populations, chronic illness, and general populations. The scale offers two scoring options: continuous 0–33 scale for severity measurement or bimodal 0–11 scoring for caseness determination, making it versatile for both research and clinical screening.
