PHQ-9 has 88% sensitivity & 88% specificity for major depression—the gold standard screening tool

Why This Assessment Matters

The PHQ-9 is the most widely used depression screening tool endorsed by NICE (UK), the VA, Kaiser Permanente, and NHS. It maps directly to DSM-5 diagnostic criteria and serves triple duty: screening, severity assessment, and treatment monitoring all in one.

✨ Key Benefits

  • Takes under 3 minutes — Fast enough for routine clinical use
  • Validated globally — Proven reliable in primary care, psychiatry, and specialty populations
  • Actionable scores — Clear cutoffs guide treatment decisions (mild: watchful waiting; moderate-severe: intervention)
  • Tracks progress — Re-test over time to monitor treatment response
  • Crisis detection — Question 9 flags suicide risk for immediate follow-up

🚨 Depression often goes unrecognized in busy clinical settings. The PHQ-9 is used by millions of clinicians worldwide because early detection changes outcomes. Available in 30+ languages and completely free to use—miss this and you might miss the hidden distress affecting your work.
