Cancer Fatigue Scale/Evidence
Method evidence record

Cancer Fatigue Scale

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.
