Multiple Sclerosis Impact Scale
What It Measures
The Multiple Sclerosis Impact Scale (MSIS-29) is a self-report questionnaire that asks how much MS has affected a persons day-to-day life over the past two weeks. Twenty of the 29 questions cover the physical impact of the disease and nine cover the psychological impact, each answered on a five-point scale running from "not at all" to "extremely."
The two scales are scored separately and converted to a 0–100 range, where a higher score means greater impact. The developers do not recommend combining them into one number. Rehabilitation teams use it in outpatient, inpatient, home health, and skilled nursing settings to track change over a course of care.
