PHQ-2 (Depression Screen)

Two-item depression screen.

Education and reference only. Not a substitute for clinical judgement, local policy or product labelling. Always verify before clinical use. Values are calculated in your browser and never stored.

When to use

Use as a first-step screen for depression; a positive result (≥3) should prompt a fuller assessment such as the PHQ-9.

Why use

It is an ultra-brief, validated first-line screen.
