PHQ-9 is the most widely used depression screen and severity measure internationally. Looking back over the past 2 weeks, answer 9 questions, total 0-27: <5 none, 5-9 mild, 10-14 moderate, 15-19 moderately severe, 20-27 severe. It helps you and your doctor quantify mood and track change. Depression is a common, treatable condition, not a weakness. Free; scored locally.

Common questions

Can PHQ-9 diagnose depression?
No. It is a screen and severity measure indicating likelihood and degree; diagnosis needs an in-person mental-health evaluation. Moderate or above warrants care.
What if item 9 is anything other than 'not at all'?
Whatever the total, if thoughts of self-harm are present, please tell someone you trust right away and see a mental-health professional or emergency department, or contact a crisis helpline. Seeking help promptly matters.
How often should I test?
During treatment or adjustment, often every 2-4 weeks to see change; also when mood fluctuates. A trend is more informative. Follow your doctor's advice.
