Podsumowanie	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 Multidimensional Fatigue Inventory is a 20-item self-report instrument that comprehensively measures five distinct dimensions of fatigue: general fatigue, physical fatigue, reduced activity, reduced motivation, and mental fatigue. Developed by Smets and colleagues in 1995, the MFI-20 is grounded in a theoretical model distinguishing fatigue phenomenology from behavioral and cognitive consequences, making it particularly valuable for research examining fatigue mechanisms and interventions targeting specific fatigue dimensions.
