Depression Test (PHQ-9)

This is a depression test based on the PHQ-9, a clinically validated self-assessment questionnaire of 9 questions about the last two weeks. Answer them and get your score from 0 to 27 straight away, with the matching band (from minimal to severe). The calculation happens entirely in your browser: we do not collect, store or send anything, and there is no need to sign up. It is a screening tool, not a diagnosis: for a reliable assessment, speak to a professional.

What the PHQ-9 is and how to read the score

The PHQ-9 (Patient Health Questionnaire, 9-item depression module) measures the severity of depressive symptoms over the last two weeks, following the nine diagnostic criteria for depression. Each question is worth from 0 (not at all) to 3 (nearly every day); the total runs from 0 to 27. The standard bands are:

  • 0-4 minimal or no depression
  • 5-9 mild depression
  • 10-14 moderate depression
  • 15-19 moderately severe
  • 20-27 severe depression

A score of 10 or above is the threshold beyond which clinically significant depression is more likely: it is a valid reason to talk it through with a professional, not a diagnosis. The PHQ-9 includes a tenth question (how difficult the problems have made everyday life) that is not part of the score and serves only as context.

An important note about the ninth question. The PHQ-9 also asks about thoughts of death or of hurting yourself. If this question applies to you even in part, the result will show you listening lines straight away, right at the top, regardless of your total score: because those thoughts matter in their own right, not because of the sum. If you are there now, do not wait: talk to someone you trust or call 999.

Frequently asked questions

Is the PHQ-9 depression test reliable?

The PHQ-9 is one of the most widely used and validated depression screening tools in clinical practice and research. It is reliable as an initial screen, but it remains a first-orientation tool: it does not replace an assessment by a professional.

Does a high score mean I have depression?

No. A high score indicates frequent symptoms over the last two weeks and suggests exploring things further with a professional, but it is not a diagnosis. Only a doctor or psychologist can assess the full picture.

Is my data safe?

Yes. The score is worked out entirely in your browser. We do not collect, store or send your answers anywhere: there are no accounts, emails or cookies tied to the test. If you reload the page, your answers disappear.
