What is the GAD-7?
The GAD-7 is a seven-item questionnaire for generalised anxiety disorder. It asks about symptoms over the last two weeks.
It also screens reasonably well for panic disorder, social anxiety and PTSD.
GAD-7 scoring

|---|
| 0–4 | Minimal |
| 5–9 | Mild |
| 10–14 | Moderate |
| 15–21 | Severe |
A score of 10 or more suggests probable generalised anxiety disorder. NICE CG113 advises NHS Talking Therapies, with sertraline first line if drug treatment is chosen.
