How this works
The PHQ-9 and GAD-7 are short questionnaires that doctors and NHS Talking Therapies use to screen for depression and anxiety and to track how someone is doing. Each answer scores 0–3.
PHQ-9: 0–4 minimal, 5–9 mild, 10–14 moderate, 15–19 moderately severe, 20–27 severe. GAD-7: 0–4 minimal, 5–9 mild, 10–14 moderate, 15–21 severe.
Good to know
- A screening score is not a diagnosis — only a clinician can diagnose depression or an anxiety disorder.
- A score of 10 or more on either scale is the usual point to talk to a GP or doctor.
- Your answers are scored in your browser and never saved or sent anywhere.
PHQ-9 and GAD-7 were developed by Drs Robert L. Spitzer, Janet B.W. Williams, Kurt Kroenke and colleagues, with an educational grant from Pfizer Inc. No permission is required to reproduce, translate, display or distribute them.
