Severity of generalized anxiety. ≈ 2 minutes to complete. Free to use.
GAD-7 (Generalized Anxiety Disorder 7-item) is a validated clinical instrument used to assess severity of generalized anxiety. It is most often used for generalised anxiety screening in primary care. The instrument contains 7 items. Typical administration time is ≈ 2 minutes.

Generalised anxiety screening in primary care. GAD-7 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.
The instrument's primary construct — severity of generalized anxiety — is operationalized through a fixed set of items, each with a defined response format. This standardisation is what allows GAD-7 scores to be compared meaningfully across clinicians, sites, and studies.
Like all screening or assessment instruments, GAD-7 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.
Answer all 7 items below to see your GAD-7 score and interpretation.
Each item is scored on a 4-point scale (0–3). Your score updates live as you answer.
All scoring runs in your browser. No data is sent anywhere — close the tab and the answers are gone.
GAD-7 uses simple summation: each item's selected response is converted to a numeric value, and the values are added to produce a total score. Reverse-scored items are inverted before summation.
Scoring notes: Screening tool, not a diagnostic instrument. Educational use only.
The cutoffs below are drawn from the published validation literature. Always interpret in clinical context.
| Score range | Band | Interpretation |
|---|---|---|
| 0–4 | Minimal / none | No anxiety suggested. |
| 5–9 | Mild | Mild anxiety. |
| 10–14 | Moderate | Moderate — needs evaluation. |
| 15–21 | Severe | Severe — active treatment indicated. |
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 | Feeling nervous, anxious, or on edge | Several days | 1 |
| 2 | Not being able to stop or control worrying | Several days | 1 |
| 3 | Worrying too much about different things | Several days | 1 |
| 4 | Trouble relaxing | Several days | 1 |
| 5 | Being so restless that it's hard to sit still | Several days | 1 |
| 6 | Becoming easily annoyed or irritable | Several days | 1 |
| 7 | Feeling afraid as if something awful might happen | Several days | 1 |
Add up all the item scores you noted in Step 1.
1 + 1 + 1 + 1 + 1 + 1 + 1 = 7
Find the row in the interpretation table whose range contains your total:
Total = 7 falls between 5 and 9 → Mild
Mild. Mild anxiety.
A score is one input alongside history and examination. GAD-7 supports clinical judgment — it does not replace it.
Psychometric figures are drawn from the validation literature and may vary across clinical populations and translations.

GAD-7 (Generalized Anxiety Disorder 7-item) is a validated instrument that assesses severity of generalized anxiety. Its primary clinical use is generalised anxiety screening in primary care.
GAD-7 typically takes ≈ 2 minutes to administer. Time can vary slightly depending on whether it is self-administered or clinician-led.
GAD-7 contains 7 items. Items are summed to produce a total score.
Scores of 15–21 fall in the "Severe" band. Severe — active treatment indicated.
Scores of 0–4 fall in the "Minimal / none" band. No anxiety suggested.
GAD-7 has reported Cronbach's α of 0.92 in validation samples and test–retest reliability of 0.83. Validated for generalised anxiety disorder; also screens reasonably for panic, social anxiety, and PTSD.
Yes — GAD-7 is in the public domain and free for clinical, educational, and research use without permission.

No. GAD-7 is a structured assessment aid. A score is one input alongside history, examination, and clinical context. Treatment decisions should never rest on a screening score alone.
