GAD-7 Scoring and Interpretation: The Complete Clinical Guide
Seven items, 0-21, two minutes — the most widely used anxiety screening and monitoring measure in the world.
What the GAD-7 measures
The GAD-7 asks how often, over the last two weeks, a person has been bothered by seven problems: feeling nervous or on edge, not being able to stop worrying, worrying too much about different things, trouble relaxing, restlessness, irritability, and feeling afraid something awful might happen.
Each item scores 0 (not at all) to 3 (nearly every day), giving a total from 0 to 21. Cut-points of 5, 10 and 15 mark mild, moderate and severe anxiety, and a score of 10 or higher is the standard threshold for probable generalised anxiety disorder.
It was designed for GAD but performs well as a screen for panic disorder, social anxiety disorder and PTSD, which is why it functions as a general anxiety measure in practice. It is public domain, free, and takes two minutes.
How to score the GAD-7
Score range: 0-21 (seven items scored 0-3)
- 1Score each item 0 = not at all, 1 = several days, 2 = more than half the days, 3 = nearly every day.
- 2Add the seven items for a total from 0 to 21. There are no reverse-scored items or subscales.
- 3Apply the bands: 0-4 minimal, 5-9 mild, 10-14 moderate, 15-21 severe.
- 4Note the unscored functional-impairment item separately in the record.
GAD-7 score interpretation
| Score | Severity | What it means clinically |
|---|---|---|
| 0-4 | Minimal anxiety | No treatment indicated on this measure. Use as the remission target when tracking treatment. |
| 5-9 | Mild anxiety | Monitor and revisit. Psychoeducation, sleep, activity and caffeine or alcohol review are usually the highest-yield actions before formal treatment. |
| 10-14 | Moderate anxiety | Probable anxiety disorder. Active treatment indicated: CBT, an SSRI or SNRI, or both. This is the standard threshold for further diagnostic assessment. |
| 15-21 | Severe anxiety | Severe anxiety with likely functional impairment. Treat actively, screen for panic, PTSD and depression, and assess suicide risk — severe anxiety raises risk independently. |
What specific GAD-7 scores mean
What does a GAD-7 score of 10 mean?
Ten is the standard cut-off for probable generalised anxiety disorder — roughly 89% sensitivity and 82% specificity. It indicates moderate anxiety and warrants diagnostic assessment and treatment, not watchful waiting.
What does a GAD-7 score of 15 mean?
Fifteen and above is severe anxiety. Expect significant functional impact, screen for comorbid depression, panic and PTSD, and treat actively with therapy, medication or both.
What is a normal GAD-7 score?
A total of 0 to 4 is minimal anxiety and the usual remission target after treatment.
How much GAD-7 change is meaningful?
A reduction of 4 points or more, or roughly 50% from baseline, is generally treated as a clinically meaningful response. A final score below 5 counts as remission.
Can the GAD-7 diagnose anxiety?
No. It is a screening and severity measure. A score of 10 or higher indicates probable disorder and calls for a clinical interview to confirm the diagnosis and rule out medical causes, substance effects and hyperthyroidism.
Reading GAD-7 and PHQ-9 together
Anxiety and depression co-occur in roughly 60% of cases, and the two measures take five minutes together. Running both is close to standard of care at intake.
When both are elevated, treating the depression usually lowers both scores, because the shared items — sleep, concentration, restlessness — respond together. When the GAD-7 stays high after the PHQ-9 improves, look for a specific anxiety disorder that needs its own treatment: panic, social anxiety, OCD or PTSD.
Common misinterpretations
- Treating 10 as diagnostic. It flags probability, not diagnosis.
- Missing panic disorder. Someone with severe episodic panic can score modestly if they avoid triggers successfully.
- Ignoring medical mimics. Hyperthyroidism, arrhythmia, stimulant and caffeine use, and alcohol or benzodiazepine withdrawal all produce elevated scores.
- Reading a small drop as improvement. Below about 4 points, movement is within measurement noise.
Using the GAD-7 as an outcome measure
Because the GAD-7 is public domain, brief and sensitive to change, it is the natural anxiety outcome measure for measurement-based care and value-based contracts.
The useful reporting unit is not the average score but the proportion of patients achieving a 50% reduction or a final score below 5 within a defined window. That is the number payers respond to, and it is what quality programmes are increasingly asking for.
Who the GAD-7 is for
- Routine anxiety screening in primary care, integrated care and behavioural health intake
- Session-by-session monitoring during therapy or medication treatment
- Paired with the PHQ-9 for a complete five-minute mood and anxiety screen
- Value-based care and quality reporting that requires a validated, repeatable anxiety measure
Administration and re-testing
- Self-report over the last two weeks. Reading it aloud gives equivalent results when literacy is a barrier.
- Score all seven items. If one is missing, ask for it rather than pro-rating the total.
- Administer at intake and then every session or every two to four weeks. Anxiety scores move fast enough that monthly measurement misses useful signal.
- The eighth question about difficulty at work, home and relationships is not scored. Read it anyway — it is often the item that changes the treatment plan.
Reliability and validity
- Internal consistency is excellent, with Cronbach's alpha typically reported at 0.89 to 0.92.
- At a cut-off of 10 the GAD-7 has 89% sensitivity and 82% specificity for generalised anxiety disorder.
- It also performs adequately as a screen for panic disorder, social anxiety disorder and PTSD, with slightly lower specificity.
- Test-retest reliability is high, and the measure is responsive to treatment, making it suitable for repeated administration.

Frequently asked questions
How do you score the GAD-7?
Score each of the seven items from 0 to 3 and add them for a total of 0 to 21. Bands are 0-4 minimal, 5-9 mild, 10-14 moderate, and 15-21 severe anxiety.
What is the GAD-7 cut-off score?
Ten or higher is the standard cut-off for probable generalised anxiety disorder and the point at which further assessment and treatment are indicated.
Is the GAD-7 free?
Yes. The GAD-7 is in the public domain and can be reproduced, translated and used without permission or fee.
Is the GAD-7 only for generalised anxiety?
It was developed for GAD but performs well as a screen for panic disorder, social anxiety disorder and PTSD, which is why it is used as a general anxiety measure.
How often should the GAD-7 be repeated?
At intake and then every session or every two to four weeks during active treatment. Monthly or quarterly measurement loses useful signal.
What is the GAD-2?
The first two GAD-7 items, scored 0-6, used as an ultra-brief screen. A score of 3 or higher should be followed by the full GAD-7.
