PHQ-9 Depression Screening

A validated 9-question screen for depression severity. Private, takes two minutes, and not stored unless you choose to.

Awaiting clinical review. Results are based on validated formulas but pending physician verification.

How this is calculated

The PHQ-9 sums your nine answers (each 0–3) into a 0–27 score, with validated severity bands. It is a screening tool, not a diagnosis.
