PHQ-9 Test

A gentle two-week check-in that shows how your days have been sitting with you and helps put it into words.

Know that feeling when everything takes more out of you than it should? This test is not out to judge you; it shows how the last two weeks have sat with you, from mood to sleep to focus. Pick the answer closest to right now, even when none fits exactly. It takes about five minutes, and at the end you get a description of where things stand. What would it change to see it named plainly?

How this test works

Where the questions come from, what the scale rests on, and why the result is not a diagnosis.

The test measures how marked self-reported signs of depression have been over the last two weeks, across mood, interest, self-worth, sleep, appetite, energy, concentration and physical slowing or restlessness.

Methodology

A result here comes from one sitting of self-report, so it shows a snapshot and says nothing about the weeks before or after. Its score bands were cut for this test alone. Research on questionnaires of this kind has found no single sharp dividing line, and a loss, a punishing season of life or another condition can produce similar answers.

The questions cover mood, energy, sleep and appetite, concentration and decisions, the way the body moves, and how much interest and self-worth remain. Each area gets three questions. Answers add up to one total, and a higher total means the signs are more marked.

The test was built independently on public research into depression symptoms. It is not the PHQ-9 questionnaire that some readers know by name: the questions, the length and the thresholds are its own, and one area of that questionnaire is deliberately not reproduced here.

For background on how screening questionnaires differ from diagnosis, MedlinePlus offers a short explainer. The NIMH page on finding help lists where to turn.

This test is not a diagnostic tool and no replacement for a specialist. It does not diagnose depression or any other condition, does not confirm or rule one out, and does not estimate the chance of one. What it reflects is a self-report of the last two weeks. Diagnosis belongs to a qualified specialist, who uses a clinical interview and personal history and applies the criteria. The test gives no clinical score.

Questions

Can this test tell me whether I have depression?

No. What it offers is a look at how the last two weeks have gone, filled in alone at a screen, and a diagnosis cannot rest on that. A qualified professional reaches one by talking with a person and learning their history. The second link in the methodology section shows where to look for that conversation.

Can I take it alone, with nobody guiding me?

Yes, it was made for exactly that: one person, start to finish, no helper needed. A conversation with a professional stays a sensible idea at any result, high or low.

Is this the same as the PHQ-9?

No, and it should not be mistaken for it. A reader who knows that questionnaire would find similar ground here, worded differently, with a different number of questions and its own thresholds. The result belongs to this test and is never a result on that questionnaire.

How is this different from an anxiety test?

Depression and anxiety often travel close together, yet they are separate territories. Everything here is built around signs of depression, so anxiety is left to tests made for it. No comparison or equivalence with any other questionnaire is claimed.

How accurate is a test like this?

Treat the result as a prompt for reflection rather than a measurement. Nobody has checked this test separately against professional assessment. Questionnaires of this general type have been studied widely and match professionals reasonably well but not perfectly, and even that research finds no exact cutoff.
