21-item revised version assessing functional status, overall impact, and symptoms of fibromyalgia. FIQR is part of standard practice in this setting because it provides a structured, replicable assessment that can be tracked over time and compared across patients or visits.
Like all screening or assessment instruments, FIQR is a structured aid — not a diagnostic test in isolation. Results should be interpreted alongside history, examination, and clinical context. Where a score crosses an actionable threshold, the next step is typically a more detailed clinical evaluation rather than a definitive diagnosis.

Each item is scored on a 11-point scale (0–10). Your score updates live as you answer.

The cutoffs below are drawn from the published validation literature. Always interpret in clinical context.
| Score range | Band | Interpretation |

| 61–100 | Severe impact | Active treatment |
This is an illustrative walkthrough, not a real patient. Follow the same four steps with your own answers — or use the live calculator at the top of this page.
Read each question and choose the response that best fits. Each response has a number next to it — that number is the item's score. The example below uses illustrative answers.
| # | Item | Example response | Score |
|---|---|---|---|
| 1 | Brush or comb your hair | 1 | 1 |
| 2 | Walk continuously for 20 minutes | 1 | 1 |
| 3 | Prepare a homemade meal | 1 | 1 |
| 4 | Vacuum, scrub, or sweep floors | 1 | 1 |
| 5 | Lift and carry a bag full of groceries | 1 | 1 |
| 6 | Climb one flight of stairs | 1 | 1 |
| 7 | Change bed sheets | 1 | 1 |
| 8 | Sit in a chair for 45 minutes | 1 | 1 |
| 9 | Go shopping for groceries | 1 | 1 |
| 10 | Overall impact of fibromyalgia on your life | 0 — No difficulty | 0 |
| 11 | Overall level of physical function | 1 | 1 |
| 12 | Level of pain | 0 — No difficulty | 0 |
| 13 | Level of energy | 1 | 1 |
| 14 | Level of stiffness | 0 — No difficulty | 0 |
| 15 | Quality of sleep | 1 | 1 |
| 16 | Level of depression | 0 — No difficulty | 0 |
| 17 | Level of memory problems | 1 | 1 |
| 18 | Level of anxiety | 0 — No difficulty | 0 |
| 19 | Level of tenderness to touch | 1 | 1 |
| 20 | Level of balance problems | 0 — No difficulty | 0 |
| 21 | Level of sensitivity to loud noises, bright lights, odors, and cold | 1 | 1 |
Add up all the item scores you noted in Step 1.
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + … (items 9–21 sum to 7) = 15
Find the row in the interpretation table whose range contains your total:
Total = 15 falls between 0 and 30 → Mild impact

A score is one input alongside history and examination. FIQR supports clinical judgment — it does not replace it.
Psychometric figures are drawn from the validation literature and may vary across clinical populations and translations.
If FIQR doesn't fit your context, related instruments in somatic include:

| BPI | 15-item measure assessing pain severity and pain interference with daily functioning. | 11 | ≈ 3 min |
| PHQ-9 | Severity of depression | 9 | ≈ 3 minutes |

FIQR (Revised Fibromyalgia Impact Questionnaire) is a validated instrument that assesses functional status, overall impact, and symptoms of fibromyalgia. It is designed for clinicians, medical students, evidence-synthesis researchers. It takes about 5 min to complete, and the 21 items are summed to produce a total score.
FIQR typically takes about 5 min to administer. The exact duration varies a little depending on whether it is self-administered or completed with a clinician. Its brief format is part of what makes it practical for routine clinical use and for repeat administration when tracking change over time.
FIQR contains 21 items. Item scores are summed to produce the total. Scores run from 0 to 100, grouped into 3 interpretation bands from ‘Mild impact’ up to ‘Severe impact’.
On the FIQR (total score 0–100), scores of 61–100 fall in the ‘Severe impact’ band — interpreted as: Active treatment. The full ladder is: 0–30 — Mild impact: Conservative management.; 31–60 — Moderate impact: Consider treatment.; 61–100 — Severe impact: Active treatment. A higher score reflects a more severe presentation, and crossing a cutoff is a prompt to step up assessment or care — but these bands are screening thresholds, not diagnoses.
Scores of 0–30 fall in the ‘Mild impact’ band: Conservative management. A low score is reassuring but does not by itself rule out the underlying condition — if symptoms or clinical suspicion persist, reassess over time or use a complementary evaluation rather than relying on the number alone.
FIQR has reported Cronbach's α of 0.95 in validation samples and test–retest reliability of 0.92. Improved sensitivity to change compared to original FIQ. In practical terms, a Cronbach’s α around 0.95 indicates excellent internal consistency (the items hang together well), and a test–retest reliability of 0.92 means scores are strongly stable when the scale is repeated without real clinical change.

No. FIQR is a structured assessment aid, not a diagnostic test. Its proper role is clinical assessment of functional status, overall impact, and symptoms of fibromyalgia — it standardizes assessment and flags who needs closer evaluation, but the result must be weighed alongside history, examination, and clinical context. When a score conflicts with your clinical impression, clinical judgment takes precedence; treatment decisions should never rest on a screening score alone.
