Generalised Anxiety Disorder (GAD) describes a persistent state of excessive worry that interferes with daily routines. The widely researched seven-item GAD-7 questionnaire provides a rapid, evidence-based snapshot by asking how often specific symptoms appeared during the previous two weeks. Resulting scores support early detection and structured dialogue with health professionals.
This interactive tool reproduces the questionnaire in a distraction-free interface. As you rate each of the first seven items from 0 to 3, a reactive engine instantly totals the points, converts them into clinically validated severity bands, and, once all responses are complete, displays both the numeric score and a colour-banded gauge for intuitive interpretation.
You might complete the screen before a routine check-up to summarise recent feelings, or between therapy sessions to spot emerging patterns; however, scores cannot account for personal context such as major life events, medication changes, or cultural factors. Results do not constitute a clinical diagnosis.
The GAD-7 instrument sums seven symptom ratings—each scored 0 (not at all) to 3 (nearly every day)—to quantify recent anxiety severity. Research shows the scale discriminates well across clinical and general populations, correlating strongly with structured interview outcomes and functional impairment indices.
The total score S is calculated as:
where Ri is the response value for item i. Possible totals range 0 – 21.
| Parameter | Meaning | Range/Type |
|---|---|---|
| Item score | User rating for one symptom | Integer 0 – 3 |
| Difficulty score | Self-reported impairment level | Integer 0 – 3 (not summed) |
| Total score S | Sum of seven item scores | Integer 0 – 21 |
| Severity band | Category assigned from S | Minimal / Mild / Moderate / Severe |
Suppose responses are 2-1-2-1-2-1-1 (items 1 – 7) and 2 for difficulty.
Total = 2 + 1 + 2 + 1 + 2 + 1 + 1 = 10 → Moderate anxiety band.
Validation studies include Spitzer et al. 2006 and Löwe et al. 2008, which report strong internal consistency (α ≈ 0.92) and convergent validity with the Beck Anxiety Inventory.

The authors distilled key DSM-5 anxiety symptoms into a concise set that still captures 90 % of diagnostic variance.
No. Ratings remain in local memory or the page URL; nothing is transmitted to any server.
Scores ≥ 10 usually warrant professional evaluation, though personal circumstances may justify earlier consultation.
The scale was validated for adults. Adolescents can screen with parental guidance, but paediatric tools are preferable.
No. It indicates severity only; diagnosis requires a comprehensive clinical interview.
