What is a common screening tool for depression in primary care?

The PHQ-9 (Patient Health Questionnaire-9) is widely recognized as a common screening tool for depression in primary care settings. This tool consists of nine questions that align with the diagnostic criteria for major depressive disorder as outlined in the DSM-5. It facilitates the assessment of the severity of depression and allows healthcare providers to monitor changes in symptoms over time, making it particularly useful in a primary care context where time is often limited.

The PHQ-9 is favored for its simplicity, ease of use, and applicability to a broad range of patients, which is essential in a primary care environment. It can be self-administered or completed with the help of a healthcare professional, offering flexibility in various settings.

While the Beck Depression Inventory and the Geriatric Depression Scale are also useful tools for assessing depression, they are not as commonly used in general primary care practices as the PHQ-9. The Hamilton Anxiety Scale is primarily focused on anxiety rather than depression, further distinguishing the PHQ-9 as the most suitable option for depression screening in primary care.
