Did You Know?
Fatigue affects 40-74% of healthcare workers—FSS mean score ≥4.0 indicates clinically significant fatigue
Why This Assessment Matters
The Fatigue Severity Scale is a 9-item assessment measuring how fatigue impacts your motivation, physical functioning, work, family, and social life. Developed by Krupp et al. (1989) for multiple sclerosis and lupus, it's now validated in Parkinson's disease, chronic hepatitis C, sleep disorders, and healthcare workers. Unlike energy scales, FSS assesses fatigue severity and its functional consequences.
✨ Key Benefits
- Quick assessment — 9 items, 7-point scale, takes 2-3 minutes
- High reliability — Internal consistency α = 0.88, test-retest r = 0.84
- Validated in healthcare — Proven during COVID-19 pandemic in frontline workers and shift workers
- Clinical cutoff — Mean score ≥4.0 = clinically significant fatigue (Swiss validation)
- Free to use — Available from Krupp et al. Archives of Neurology 1989
😩 Clinically significant fatigue in healthcare workers leads to medical errors, reduced patient safety, and increased turnover. Night shift workers and residents are at highest risk. The FSS mean score >4 was found in 62% of sleep disorder patients. Don't ignore fatigue—it's a warning sign.
