Common questions
What is the PHQ-9?
The PHQ-9 — the Patient Health Questionnaire-9 — is a 9-question depression test used in clinics worldwide. It asks about depression symptoms over the past two weeks and scores them from 0 to 27. Many people look it up as the PHQ9 quiz or PHQ-9 depression test.
Is the PHQ-9 a diagnosis?
No. It's a screening tool that suggests whether depressive symptoms may be present and how severe they look right now. Only a licensed clinician can diagnose depression.
What should I do with my score?
Use it as a starting point for a conversation — with your doctor, a therapist, or someone you trust. Higher scores are a stronger nudge to reach out soon.
How often can I retake it?
As often as you like. Some people retake it every couple of weeks to see how they're trending — your answers are never stored, so each check starts fresh.
The PHQ-9 was developed by Drs. Robert L. Spitzer, Janet B.W. Williams, Kurt Kroenke and colleagues, with an educational grant from Pfizer Inc. No permission required to reproduce, translate, display or distribute.
