Depression Assessment Test

The PHQ-9 (Patient Health Questionnaire-9) was developed in 1999 by Columbia University professors Robert Spitzer, Janet Williams, and Kurt Kroenke. Compared to the Beck Depression Inventory from 1961, it’s lighter on questions—just nine—but heavier on relevance. It’s built around today’s diagnostic criteria and takes just a few minutes to complete. And because of its flexible scoring system, it’s not only great for one-time screening, but also useful for tracking shifts in your emotional state over time. Think of it as a low-pressure way to get a clearer read on what’s going on below the surface.

Of course, no quiz—no matter how well designed—can replace a conversation with a qualified professional. The PHQ-9 is a starting point, not a final word. It’s meant to give you a snapshot, not a diagnosis. But sometimes, that snapshot is the nudge you need to get curious about your own mental health. Whether your next step is a talk with a psychiatrist, a more holistic approach, or simply being more honest with yourself—what matters is that you start. And if you're ready for that, support is here.
