Assessment of Subjective Physical and Mental Fatigue
The Chalder Fatigue Scale is a standardized questionnaire used to assess subjective physical and mental fatigue and to monitor changes over time.
The questionnaire includes items related to physical fatigue, energy, the need for rest, concentration, speech and memory.
Please answer each question based on how you have felt during the past 30 days, compared with your usual state.
There are no “right” or “wrong” answers. It is important that your responses reflect your actual experience.
How is the questionnaire used?
The questionnaire can be completed as a baseline assessment and then repeated at appropriate intervals to monitor changes in subjective fatigue levels.
The result represents one element of an overall health assessment and can be considered together with symptoms, lifestyle habits, personal goals and other available health information.
TOTAL CHALDER FATIGUE SCALE SCORE [automatically calculated score]
A higher score indicates a greater level of subjective fatigue.
Note: The Chalder Fatigue Scale score represents one element of an overall health assessment. It should be considered in the context of other information about your health status, lifestyle habits, symptoms and daily functioning.
The Chalder Fatigue Scale assesses the subjective experience of physical and mental fatigue. It is not a medical diagnostic tool and cannot, on its own, determine the cause of fatigue.
If you have persistent, severe, new or concerning symptoms, please consult an appropriate healthcare professional.
