The MFI-20 is a 20-item self-reported measurement of fatigue. It includes five dimensions: General Fatigue (GF), Physical Fatigue (PF), Mental Fatigue (MF), Reduced Motivation (RM) and Reduced Activity (RA). Every item is rated on a 5-point Likert scale, every subscale's single total scores is summed up ranging from 4 to 20 scores. Higher total scores indicates higher level of fatigue. Validity and internal consistency have been verified to be good for different populations [24].
