Резюме	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.	The Brief Fatigue Inventory is a 9-item patient self-report instrument specifically designed for rapid, repeated assessment of cancer-related fatigue severity and its functional impact. Developed by Mendoza, Cleeland, and colleagues at M.D. Anderson Cancer Center in 1999, the BFI is optimized for use in busy oncology clinics, allowing comprehensive fatigue profiling in 2–3 minutes without sacrificing clinical validity.
