Modified Fatigue Impact Scale (MFIS)

Clinical intent

Fatigue is an extremely common, but under-recognized, symptom in MS. In fact, 84.0% of the MSQLI Field Test sample reported fatigue as a current MS symptom. The MSQLI Modified Fatigue Impact Scale (MFIS) consists of 21 items selected from the Fatigue Impact Scale (FIS; Fisk, Ritvo, Ross, Haase, Murray, & Schlech, 1994), a multidimensional scale developed to assess the perceived impact of fatigue on a variety of daily activities.

Clinical interpretation

Higher scores indicate a greater impact of fatigue on a patient’s activities.
