Frequently asked questions
Does a PHQ-9 score of 10 mean I have depression?
A 10 is the start of the moderate range (10-14), signaling symptoms that may affect daily life. But no single score diagnoses depression. PHQ-9 is only a screening tool, so if a score of 10 or higher lasts more than two weeks, see a mental-health professional for a proper evaluation.
I scored 13 — do I have to see a doctor?
A 13 falls in the moderate range, where a professional consultation is recommended. It does not mean immediate danger, but if symptoms last over two weeks or disrupt work, relationships, or sleep, consider a psychiatrist or a free public mental-health center. If you have thoughts of self-harm, seek help right away regardless of the score.
What happens if I answer 1 or more on item 9 (suicidal thoughts)?
Answering 1 or higher on item 9 immediately shows crisis-support contacts on screen, regardless of total score. These include 24/7 lines (Korea: 109 and 1577-0199; US: 988). Please do not face this alone — reach out now, or call your local emergency number if it is urgent. This is the most important part of the tool.
How accurate is PHQ-9?
PHQ-9 is a well-validated depression screener in primary care, with sensitivity and specificity around 88% at a cutoff of 10. That is screening accuracy, not a confirmed diagnosis. Physical illness, medication, and sleep issues can affect the score, so an accurate diagnosis still requires a clinician interview.
How often should I retake it?
Because PHQ-9 asks about the past two weeks, retaking it every two weeks lets you track change. It is also used to monitor progress during treatment or therapy. Rather than fixating on a daily number, watching the broader trend every 2-4 weeks is more helpful.
Are my answers stored on a server?
No. All answers stay only in your browser via localStorage, and the result-share link merely encodes an answer code in the URL — nothing is sent to any server. Your sensitive mental-health information never leaves your device, so you can use it with confidence.
If I share my result on social media, is my score exposed?
The social-share text deliberately omits the score. Exposing a score can create stigma, so the share text only carries a neutral campaign line and the link. Only someone who receives the direct result link can reproduce the result from the same answers.
