• B. The Patient Health Questionnaire-9 (PHQ-9)
• C. The Hamilton Depression Scale
• D. The Zung Self-Rating Depression Scale

Answer: (B)

The Patient Health Questionnaire-9 (PHQ-9) is widely recognized as an effective tool for assessing the severity of depression. It consists of nine items that directly correspond to the diagnostic criteria for major depressive disorder as outlined in the DSM-5. Each item reflects on the frequency of depressive symptoms experienced by the individual over the past two weeks, scored from 0 to 3, allowing for a total score that can indicate the level of severity—ranging from minimal to severe depression. This questionnaire is appreciated for its ease of use and the brevity of its format, making it suitable for both clinical settings and research. It is often used in primary care and mental health practices to systematically identify depression and monitor treatment progress over time. The straightforward nature of the PHQ-9 helps in fostering patient engagement and encourages discussions about mental health symptoms during consultations. Other assessment tools, while also valid and useful, may have different applications or complexities that limit their prevalence in routine screening compared to the PHQ-9. For instance, the Hamilton Depression Scale, though comprehensive and effective, is often administered by trained clinicians and may not be as readily used in general practices. Similarly, the Beck Depression Inventory and the Zung Self-Rating Depression Scale serve well for
