Fatigue Assessment Scale (FAS)

The Fatigue Assessment Scale (FAS) is a 10-item self-report questionnaire measuring the severity of fatigue. It includes two subscales: Physical Fatigue (Q1-5, range 5-25) and Mental Fatigue (Q6-10, range 5-25). Total score ranges from 10-50, with higher scores indicating greater fatigue.

Instructions:

The following ten statements refer to how you usually feel. Per statement you can choose one out of five answer categories, varying from Never to Always. Please select the answer to each question that is applicable to you. Please give an answer to each question, even if you do not have any complaints at the moment.
