Which screening tool is known for its high sensitivity in assessing major depression?

The correct choice reflects an understanding of the various screening tools used in the assessment of major depression, particularly in a perinatal context. The PHQ-2, which is a shorter version of the PHQ-9, focuses on the most common symptoms of depression—lack of interest or pleasure in activities and feeling down, depressed, or hopeless. Its design allows for quick screening, making it particularly useful in settings where time is limited.

The reason the PHQ-2 is specifically noted for its high sensitivity is that it efficiently captures core depressive symptoms, enabling clinicians to identify those who are at risk for major depression. However, it is important to note that while the PHQ-2 has high sensitivity, it is typically used as a preliminary screening tool. If the PHQ-2 suggests possible depression, it is often followed up with the more comprehensive PHQ-9, which offers a fuller picture by assessing the severity of depression based on additional symptoms.

In context, while options like the Edinburgh Postnatal Depression Scale and the Postpartum Depression Screening Scale are well-established tools that also have strong utility in perinatal situations, the PHQ-2’s specificity in quickly identifying at-risk individuals gives it an edge in sensitivity for early detection.
