Takeaway
The Arabic adaptation of the Modified Fatigue Impact Scale (A-MFIS) has high reliability and validity to assess fatigue in people with multiple sclerosis (MS).
Why this matters
Fatigue is a common symptom in people with MS, and the MFIS is an accepted assessment used to measure fatigue in English-speaking populations.
An Arabic adaptation of the MFIS has not been studied, and understanding this tool may lead to improved clinical outcomes in Arabic-speaking people with MS.
