Clinical context: when GAD-7 is used

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.

Score GAD-7

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.

How GAD-7 is scored

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.

How to score GAD-7: a step-by-step worked example

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.

Step 1 — Score each item

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.

#ItemExample responseScore
1Feeling nervous, anxious, or on edgeSeveral days1
2Not being able to stop or control worryingSeveral days1
3Worrying too much about different thingsSeveral days1
4Trouble relaxingSeveral days1
5Being so restless that it's hard to sit stillSeveral days1
6Becoming easily annoyed or irritableSeveral days1
7Feeling afraid as if something awful might happenSeveral days1

Step 2 — Add up the scores

Add up all the item scores you noted in Step 1.

1 + 1 + 1 + 1 + 1 + 1 + 1 = 7

Step 3 — Look up the band

Find the row in the interpretation table whose range contains your total:

Total = 7 falls between 5 and 9 → Mild

Step 4 — What does this mean clinically?

Mild. Mild anxiety.

A score is one input alongside history and examination. GAD-7 supports clinical judgment — it does not replace it.

Frequently asked questions about GAD-7

What does GAD-7 measure?

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. It takes about 2 minutes to complete, and the 7 items are summed to produce a total score.

How long does GAD-7 take to complete?

GAD-7 typically takes about 2 minutes 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.

How many items are on GAD-7?

GAD-7 contains 7 items. Item scores are summed to produce the total. Scores run from 0 to 21, grouped into 4 interpretation bands from ‘Minimal / none’ up to ‘Severe’.

What is a high GAD-7 score?

On the GAD-7 (total score 0–21), scores of 15–21 fall in the ‘Severe’ band — interpreted as: Severe — active treatment indicated. The full ladder is: 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. 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.

What is a low GAD-7 score?

Scores of 0–4 fall in the ‘Minimal / none’ band: No anxiety suggested. 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.

How reliable is GAD-7?

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. In practical terms, a Cronbach’s α around 0.92 indicates excellent internal consistency (the items hang together well), and a test–retest reliability of 0.83 means scores are strongly stable when the scale is repeated without real clinical change.

Is GAD-7 free to use?

Yes — GAD-7 is in the public domain and free for clinical, educational, and research use without permission. You can use this calculator and the scale itself freely; if you publish results or reproduce the scale, cite the original source paper.

What is the source paper for GAD-7?

Spitzer RL et al. Arch Intern Med. 2006;166(10):1092-1097. This is the original publication for the GAD-7 — the reference to cite when reporting results.

Can GAD-7 replace clinical judgment?

No. GAD-7 is a structured assessment aid, not a diagnostic test. Its proper role is Generalised anxiety screening in primary care — 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.
