What is the most commonly used screening tool to rate the severity of depression?

Using a brief, self-administered tool that mirrors DSM criteria to quantify how severe depression is, and that can be easily repeated to monitor change, is essential in everyday clinical practice. The Patient Health Questionnaire, especially the PHQ-9, fits this need best. It consists of nine items about symptoms over the past two weeks and yields a total score from 0 to 27. This score corresponds to severity ranges (eg, mild, moderate, moderately severe, severe) and directly helps guide level of care and follow-up. Its brevity, simplicity in scoring, and strong validation across diverse populations make it the tool most commonly used in routine settings to screen for depression and gauge severity over time. The other scales have useful roles but aren’t as practical for broad screening in typical care. The Geriatric Depression Scale is tailored for older adults, the Beck Depression Inventory is longer and often used in research or more specialized settings, and the Hamilton Depression Rating Scale is clinician-rated and time-consuming, making it less suitable for quick screening in busy practices.
