What It Measures
The MFIS is a modified form of the Fatigue Impact Scale (Fisk et al., 1994) based on items derived from interviews with MS patients concerning how fatigue impacts their lives. This instrument provides an assessment of the effects of fatigue in terms of physical, cognitive, and psychosocial functioning.
