Chalder Fatigue Questionnaire - 11-item version
The Chalder Fatigue Questionnaire 11-item version measures physical and mental fatigue symptoms for clinician review. This page is catalogue information. It does not order blood tests.
Overview
What is the CFQ-11?
CFQ-11 organises fatigue-symptom reporting. It does not diagnose chronic fatigue, anaemia, or a sleep disorder, and it does not determine laboratory orders.
Development and clinical use
Chalder and colleagues published the fatigue questionnaire. Later 11-item use is described in the source literature. Confirm the official form before live use.
