About this test
The Patient Health Questionnaire (PHQ-9) was developed by Kroenke, Spitzer and Williams and is free to use. Scores of 5, 10, 15 and 20 mark mild, moderate, moderately severe and severe depression symptoms.
A score of 10 or more is a reason to see a doctor or mental health professional. If you have any thoughts of hurting yourself, reach out for help now, whatever your total score.

FAQ
What does my PHQ-9 score mean?
0–4 minimal, 5–9 mild, 10–14 moderate, 15–19 moderately severe and 20–27 severe depression symptoms.
Can the PHQ-9 diagnose depression?
No. It is a screening tool. A doctor or mental health professional makes a diagnosis after a full assessment.
Why does question 9 matter so much?
It asks about thoughts of death or self-harm. Any answer other than "not at all" deserves a conversation with a professional, even if the total score is low.
Is depression treatable?
Yes. Therapy, medication, exercise and social support all help, and most people improve with treatment.
