Σύνοψη	The Piper Fatigue Scale is a 22-item multidimensional self-report instrument that evaluates cancer-related fatigue across four conceptually distinct domains: behavioral/severity, affective/meaning, sensory, and cognitive/mood. Developed by Barbara Piper and colleagues in 1989 and revised in 1998, the PFS is grounded in a theoretical model of fatigue mechanisms and is widely used in oncology research and clinical practice to assess treatment-related and disease-related fatigue.	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.
