Interpretation notes

The PHQ-9 is a screening and severity-monitoring tool, not a diagnosis — a positive screen prompts clinical evaluation. A score ≥ 10 has good sensitivity and specificity for major depression.

Item 9 is independent of the total.A patient can have a low overall score and still endorse suicidal thoughts — that response is acted on regardless. A tenth question about functional difficulty (not scored) helps gauge impact but doesn’t add to the 0–27 total.

Educational use only. The PHQ-9 supports screening and monitoring; diagnosis, treatment, and safety decisions are clinical judgments made by qualified providers per facility policy. This material supports nursing education and exam review. It is not medical advice and is not a substitute for clinical judgment, institutional policy, or medical direction. Always follow facility protocols and current provider orders.
