What the PHQ-9 measures
The PHQ-9 asks how often nine symptoms have bothered you. Each item is scored 0–3 and the total ranges from 0–27. Established ranges describe symptom severity; they do not by themselves establish a diagnosis.
None–minimal symptom range.
Mild symptom range.
Moderate symptom range.
Moderately severe symptom range.
Severe symptom range.
Any positive response to the self-harm/death-thought item needs appropriate follow-up; that item alone cannot determine immediate suicide risk.
Scoring and interpretation
Responses are scored 0 for “Not at all,” 1 for “Several days,” 2 for “More than half the days,” and 3 for “Nearly every day.” The nine scores are added for a total from 0 to 27.
The complete score and severity range are free. We do not make someone pay to learn their basic clinical screening result or see safety guidance.
A positive screen should be followed by additional assessment before diagnosis or treatment decisions.
Safety
One PHQ-9 item asks about thoughts of being better off dead or hurting yourself. A positive answer is important, but PHQ-9 item 9 is not a complete suicide-risk assessment.
If you may act on self-harm thoughts, have a plan, or cannot stay safe, use emergency/crisis help now. In the U.S., call or text 988; call 911 for a life-threatening emergency.
What this screen can and cannot tell you
Depression diagnosis depends on more than a total score. A professional may consider functioning, duration, bipolar symptoms, grief, medical causes, medication effects, substance use, sleep, and other mental-health conditions.
This screening implementation should not be treated as a validated clinical or diagnostic tool unless an independent qualified reviewer verifies the exact instrument version, wording, scoring, safety behavior, sources, privacy flow, and U.S.-first care guidance.

Frequently asked questions
No. It is a screening and symptom-severity tool. Positive results need further assessment before diagnosis.
Yes. The total score, severity range, safety guidance, limitations, and basic next steps are free with no signup or email required.
The result page immediately prioritizes safety guidance. Item 9 alone cannot determine immediate suicide risk, so a fuller safety assessment may be needed.
What the score means
The total is useful because it summarizes nine depressive symptoms over the same time window. It does not determine whether symptoms come from major depression, bipolar depression, grief, trauma, a medical condition, medication effects, substance use, sleep disruption or another cause.
| Use the PHQ-9 for | Do not use it for |
|---|---|
| Screening for current depressive symptoms | Making a diagnosis without clinical assessment |
| Describing severity and functional impact | Choosing medication or treatment by score alone |
| Tracking symptoms over time | Ruling out bipolar disorder or other explanations |
Any response involving thoughts of death or self-harm deserves direct safety follow-up regardless of the total score. For broader interpretation, read the depression symptoms and help hub and depression vs sadness.
If the result concerns you, note which symptoms are most disruptive and whether they are affecting sleep, work, study, relationships or self-care. Bring the score to a professional conversation if useful, but describe the actual pattern rather than relying on the number alone.
Any self-harm or suicide-related response deserves direct follow-up. A low total score should not be used to dismiss immediate safety concerns.
No payment or email is required to complete this free assessment. Your basic result is shown in the assessment flow, and any optional paid report is presented separately.
