What this depression test measures
This test is a self-screen based on the PHQ-9, a short questionnaire that doctors use to check for signs of depression. It asks how often you've felt certain ways over the past two weeks. It gives you a score that suggests how mild or severe your symptoms might be.
A score here is a starting point, not a diagnosis. It can help you put words to what you're feeling and decide whether to talk to someone.
What is the PHQ-9?
The PHQ-9 is one of the most widely used depression screening tools in the world. Doctors and therapists rely on it because it's quick, validated, and easy to understand.
It has nine questions, each tied to a common symptom of depression. You rate how often each one has bothered you recently. The answers add up to a score that places your symptoms on a scale from minimal to severe. It's the same tool many clinics use during a checkup.
What do the results actually mean?
Your score sorts your symptoms into bands, from minimal to severe. Higher scores suggest more or stronger symptoms over the past two weeks.
Roughly, the bands look like this:
- Minimal: few or no symptoms right now.
- Mild: some symptoms worth keeping an eye on.
- Moderate: symptoms that may be affecting your daily life.
- Moderately severe: symptoms that often need professional support.
- Severe: strong symptoms where reaching out to a doctor soon really helps.
Wherever you land, the number isn't a label. It's information you can bring to someone who can help.
What does depression actually feel like?
Depression is more than feeling sad for a day. It's a low mood or loss of interest that sticks around for weeks and touches many parts of life.
It can show up in your emotions, your body, and your thinking all at once. Some people feel empty rather than sad. Others mostly notice physical changes, like exhaustion or trouble sleeping. There's no single way it looks, and your experience is valid even if it doesn't match what you expected.
What are the common signs of depression?
Depression shows up in a cluster of symptoms, not just one. The PHQ-9 is built around the most common ones.
Signs that mental health professionals look for include:
- Feeling down, empty, or hopeless most of the day.
- Losing interest in things you used to enjoy.
- Sleeping too much or too little.
- Feeling tired or low on energy.
- Changes in appetite or weight.
- Trouble concentrating or making decisions.
- Feeling bad about yourself or like a failure.
- Moving or speaking more slowly, or feeling restless.
You don't need to have every symptom for it to matter. Even a few, if they linger, are worth paying attention to.
What causes depression?
Depression rarely has a single cause. It usually grows from a mix of things working together.
Genetics, brain chemistry, stressful life events, and certain health conditions can all play a part. A family history can raise your chances, and so can long stretches of stress, loss, or trauma. Sometimes there's a clear trigger, and sometimes there isn't one at all. None of this means you brought it on yourself.
Is online screening accurate?
It's a helpful guide, not a clinical diagnosis. A self-screen can flag symptoms, but it can't see your full picture.
Only a doctor or mental health professional can diagnose depression. They consider your history, rule out other causes like thyroid issues, and talk with you in depth. So treat your result as a useful nudge toward a conversation, rather than a final answer.
Could it be something other than depression?
Sometimes, yes. A few conditions share symptoms with depression, which is why a professional assessment matters.
Anxiety often overlaps with low mood, and you can explore that with the Anxiety Test. Bipolar disorder includes depressive periods alongside high-energy ones, which the Bipolar Test screens for. Burnout, grief, and thyroid problems can also feel similar. A doctor can help tell these apart so you get the right support.
Is depression treatable?
Yes, very much so. Depression is one of the most treatable mental health conditions, and most people improve with the right help.
Treatment often combines talk therapy, like cognitive behavioral therapy, with medication when needed. Lifestyle support, regular routines, and connection with others can help too. Finding the right approach can take some adjustment, but improvement is genuinely possible. You can read more in our guide on understanding depression.
When should you talk to someone?
If your symptoms have lasted more than two weeks or are affecting your daily life, it's a good time to reach out. You don't have to wait until things feel unbearable.
A doctor, therapist, or even a trusted person in your life is a good place to start. Asking for help is a sign of strength, not weakness. If you ever have thoughts of harming yourself or feel unable to stay safe, please contact a doctor or a crisis helpline right away, or reach out to someone you trust. You deserve support, and help is available.
Using your result as a first step
Think of this screen as one small, brave step toward understanding how you feel. It's not the end of the story.
Whatever your score, you can bring it to a professional and talk things through. If low mood is tangled up with stress or self-worth, the Self-Esteem Test might offer more insight too. You don't have to figure this out alone, and reaching out is always okay.
