AB  - The determination of the minimum clinically important difference (MCID) is an 
      important aspect of scale development. The Neurological Fatigue Index for 
      multiple sclerosis (NFI-MS) was administered before and after expected change or 
      stability in fatigue in 208 multiple sclerosis (MS) patients. The overall change 
      scores of the NFI-MS accorded with perceived direction of change; importantly, no 
      change was seen when none was perceived. Using the interval level NFI-MS scores, 
      the largest MCID equated to 2.49 points on the Summary scale, 2.36 points on the 
      Physical scale, 0.84 points on the Cognitive scale, 0.97 on the Diurnal Sleep 
      scale and 1.95 on the Nocturnal Sleep scale. Our conclusion is that the NFI-MS 
      responds as expected to changes in fatigue and has desirably small MCID scores.
