Example
- Widespread Pain Index
- 8
- Fatigue severity
- 2 — moderate, often present
- Waking unrefreshed
- 2 — moderate, often present
- Cognitive symptoms
- 1 — slight / mild, intermittent
- Headaches
- Yes
- Generalized pain
- 4
- Symptoms present at a similar level for >=3 months
- Yes
Result: 2016 ACR fibromyalgia criteria MET — WPI 8/19, SSS 6/12.
The tool opens with these values already filled in. Replace them with your own.
What you enter
- Widespread Pain Index: painful regions (0-19)
- Fatigue severity
- Waking unrefreshed
- Cognitive symptoms
- Headaches (somatic-symptom count, past 6 months)
- Lower-abdominal pain or cramps (somatic-symptom count)
- Depression (somatic-symptom count)
- Generalized pain: regions with pain (of 5)
- Symptoms present at a similar level for >=3 months
How this is calculated
- Inputs
- WPI (0–19 painful regions) and SSS (0–12 = fatigue + waking unrefreshed + cognitive, each 0–3, plus a 0–3 count of headaches / lower-abdominal pain / depression).
- Criteria
- met when (WPI ≥ 7 and SSS ≥ 5) OR (WPI 4–6 and SSS ≥ 9), AND generalized pain (≥ 4 of 5 regions), AND symptoms ≥ 3 months. Valid irrespective of other diagnoses.
