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.
