PHQ-9 (Patient Health Questionnaire-9)

Am I depressed?

This 9-question PHQ-9 test (about 1 to 2 minutes) estimates the severity of depressive symptoms. It is intended for any adult wanting to check in on their mental state. The result classifies symptoms into five levels, from minimal/absent to severe.

How severe are my depressive symptoms? A 9-question test, the PHQ-9, to find out.

9 questions · about 1 to 2 minutes · Free, no sign-up

Please read before you start: this guidance tool does not replace a medical consultation. It does not provide a diagnosis.

  • A low or normal result does not rule out the need to see a doctor if you have another symptom that this specific test does not cover.
  • Depending on your age or the guidelines in your country, a consultation may still be advisable even with a negative result.

If you are having suicidal thoughts

If you are having thoughts of harming yourself or not wanting to live anymore, contact 3114 immediately, France's national suicide prevention line, free and available 24/7. You can also go to the emergency room or call 15 (SAMU) in France — outside France, look up your local emergency number. You are not alone, and help is available.

If you are having suicidal thoughts

If you are having thoughts of harming yourself or no longer wanting to live, in France contact 3114 immediately, the national suicide prevention line, free and available 24/7. You can also go to an emergency room or call emergency services. Outside France, look up your local equivalent. You are not alone, and help exists.

Feeling down or clinical depression?

Feeling down is temporary (a few hours to a few days), often tied to an identifiable event (a disappointment, a setback), and doesn't prevent normal daily functioning. Clinical depression is distinguished by its duration (at least two consecutive weeks) and intensity: it affects daily functioning — work, relationships, sleep, appetite, concentration — and doesn't necessarily need an identifiable external cause. The PHQ-9, used in the tool above, specifically covers the last two weeks for this reason.

A screening tool, not a diagnosis

The PHQ-9 (Patient Health Questionnaire-9) was designed both as a screening tool and as a measure of depressive symptom severity, but it remains subject to clinical confirmation. A high score signals symptoms worth taking seriously and discussing with a healthcare professional, but only a doctor or psychiatrist can diagnose depression, taking the person's overall context into account.

Where to find help

Your doctor is a good first point of contact: they can assess your situation and refer you, if needed, to a psychiatrist or psychologist. In an emergency or if you have suicidal thoughts, in France 3114 (national suicide prevention line, free, 24/7) is available at any time. Talking about how you feel early, before the situation worsens, generally makes support easier.

Frequently asked questions

What is the difference between feeling down and clinical depression?

Feeling down is temporary and doesn't prevent normal functioning. Clinical depression lasts at least two weeks and affects daily functioning, without necessarily needing an identifiable cause.

What should I do if I have suicidal thoughts?

In France, contact 3114 immediately, the national suicide prevention line, free and available 24/7. You can also go to an emergency room.

What should I do if my result falls in the "mild" or "moderate" zone?

A mild score is worth mentioning to your doctor if symptoms persist beyond a few weeks. A moderate score or higher is worth discussing with a healthcare professional without waiting, so they can assess your situation and refer you if needed.

Why Hygietest?

Hygietest is a health hub dedicated to primary care, centered on prevention. The idea is simple: bring together, in one place, several screening tools accessible to everyone, to help each person better understand their health even before seeing a doctor.

Multiple tools, focused on prevention

The site is gradually offering several screening tools, covering prevention in general and cardiovascular health in particular — two areas where catching an early signal often changes what comes next: sleep, blood pressure, weight, chronic fatigue. Each tool is designed for one-off use, with no account and no tracking over time.

Simple tools, built on serious foundations

Each questionnaire is based on studies from the medical literature — both established and recent — already used in clinical practice. Hygietest's job is to make them accessible: the same method, the same rigor, but language designed to be understood without any medical training.

Free, with no personal data collection

Hygietest is entirely free. No identity is requested, no payment details, no account creation. Calculations happen directly in your browser: nothing is transmitted, nothing is stored.

What Hygietest is not

Hygietest does not replace, and is not intended to replace, a medical consultation — whether as part of a screening approach or when symptoms appear. A reassuring result never rules out the possibility of seeing a doctor: if doubt remains, or if a symptom not covered by the test worries you, talking to a healthcare professional remains the right approach.

Screening is not diagnosing

This is an important distinction, often misunderstood: a screening tool doesn't serve the same purpose as a diagnostic test. Its main value lies in its ability to flag a risk — its sensitivity — rather than to confirm a diagnosis with certainty, which is the role of specificity and further testing carried out by a doctor. A positive result on a screening test is therefore not a diagnosis: it's an indication that it's worth discussing with a healthcare professional, who will decide whether further tests are needed.

Our goal

Hygietest is purely a tool for making screening more accessible, designed as a complement — never a substitute — to the usual care pathway. The ultimate goal is simple: promote screening to support prevention, by increasing the likelihood that people take the step of seeing a doctor when it's useful to do so.

Frequently asked questions
Is Hygietest free?

Yes. Every test is free, with no sign-up required.

Who is behind Hygietest?

The site is offered and reviewed by Dr. BARTHELEMY Pierre L., a general practitioner. The tests weren't invented for the site: they are scores published in medical journals and recommended by health authorities.

Are the tests reliable?

Each tool reuses the questions, formulas, and thresholds from the original publication. Sources are cited on every page. Like any screening test, they estimate a risk: they don't confirm or rule out a disease.

Can a test replace a medical consultation?

No. A low result doesn't rule out seeing a doctor if a symptom worries you, and a high result is a reason to discuss it with your doctor. In an emergency, call your local emergency number.

What happens to my answers?

Nothing: calculations happen in your browser. No answer is transmitted to or stored by Hygietest. The site measures its audience anonymously and in aggregate (page views, country, device type), without cookies, via Vercel; your test answers are never included.

Which tests are offered?

Fourteen tests: cardiovascular risk (SCORE2), cardiovascular risk with diabetes (SCORE2-Diabetes), high blood pressure (home blood pressure monitoring), diabetes risk (FINDRISC), overweight and obesity (BMI), fatty liver disease (FLI), liver fibrosis (FIB-4), sleep apnea (STOP-BANG), sleepiness (Epworth Sleepiness Scale), nicotine dependence (Fagerström test), alcohol consumption (AUDIT-C), physical activity (IPAQ/GPAQ), burnout (CBI), and depression (PHQ-9).

Which test should I start with?

If you don't have a specific question in mind, start with cardiovascular risk and blood pressure: the two most useful markers in prevention.
