PHQ-9

Depression Severity

For education. Check every result.

Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.

Fill in every field above, then select Calculate.

How it is calculated

PHQ-9 is a severity measure, not a diagnosis. item 9 asks about thoughts of self-harm and any positive answer requires a direct risk assessment regardless of the total score.
