Depression screening takes only a few minutes.

Quick answer

Depression screening uses short validated questionnaires, most commonly the PHQ-2 and PHQ-9, to identify people who may have depression. The U.S. Preventive Services Task Force recommends screening all adults, including pregnant and postpartum people. PHQ-9 scores of 5, 10, 15 and 20 suggest mild, moderate, moderately severe and severe symptoms. A positive screen leads to a full clinical evaluation.

Key takeaways

Screening is recommended for all adults in primary care.
The PHQ-9 asks about 9 symptoms over the past 2 weeks.
Scores guide next steps but do not diagnose on their own.
The self-harm question is always followed up promptly.
Screening is free in many settings and can be repeated to track progress.

Depression often goes unnoticed, even by the person experiencing it. That is why doctors use quick questionnaires to check in on mood. If you have filled out a short form asking about sleep, energy and interest in activities, you have had a depression screening.

What is depression screening?

Screening is a brief, standardized way to identify people who may need further evaluation for depression. It is not a diagnosis. The U.S. Preventive Services Task Force recommends depression screening for all adults, including pregnant and postpartum people, and anxiety screening for adults under 65.
