תקציר	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 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.
