Objective[edit | edit source]

The Fatigue Severity Scale is a 9-item scale which measures the severity of fatigue and its effect on a person's activities and lifestyle in patients with a variety of disorders. It was originally devised for people with Multiple Sclerosissorystemic lupus erythematosus[1].

[2]

Intended Population[edit | edit source]

Those with a variety of diagnoses including arthritis, fibromyalgia, Multiple sclerosis, Parkinson’s disease and stroke.

Method of Use[edit | edit source]

A self-report scale of nine items about fatigue, its severity and how it affects certain activities. Answers are scored on a seven point scale where 1 = strongly disagree and 7 = strongly agree. This means the minimum score possible is nine and the highest is 63. The higher the score, the more severe the fatigue is and the more it affects the person's activities.

Evidence[edit | edit source]

Reliability[edit | edit source]

Test-retest Reliability[edit | edit source]

One study reported excellent test-retest reliability (ICC = 0.91) in a Brazilian-Portuguese version for people with PD (n = 30, mean age = 62 (11) years, mean time post- PD = 7.6 (6.5) years)[3].

Interrater/Intrarater Reliability[edit | edit source]

Validity[edit | edit source]

Parkinson’s Disease

  • Excellent (r = -0.77) negative correlation with Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale[4]
  • Excellent (r = 0.62) correlation with Nottingham Health Profile (NHP-EN) scale[4]
  • Excellent (r = 0.84) correlation with Parkinson’s Fatigue (PFS) scale [5]
  • Poor-adequate (r = 0.22-0.47) correlation with Parkinson’s Disease Questionnaire-39 (PDQ-39) scale; n = 66, mean age = 70.8 (9.9) years, time since PD = 70.2 (56.1) months) [6]
