The Depression Screen Used in 80 Countries — and Why Most People Who Need It Have Never Taken It

---

Depression does not always look like sadness.

That’s the first thing that makes it so consistently under-identified — especially in adults, especially in men, and especially in cultures where emotional difficulty is supposed to be handled privately.

Depression often looks like numbness. Flatness. A loss of interest in things that used to matter without a clear reason why. A subtle but persistent sense that effort doesn’t connect to outcomes. Sleep that doesn’t restore. Irritability that seems disproportionate. The feeling that you’re going through the motions of your own life.

What Is the PHQ-9?

The Patient Health Questionnaire-9 was developed by Kroenke and Spitzer in 2001 and has since become the most widely validated depression screening instrument in clinical medicine. It’s used in hospital systems, GP surgeries, and research studies across more than 80 countries.

Nine questions. It maps directly to the DSM diagnostic criteria for Major Depressive Disorder — not because it diagnoses, but because it screens for the presence and severity of the same symptom clusters that clinicians use to assess and diagnose.

Why Depression Goes Undiagnosed in India

An estimated 56 million people in India live with depression. The treatment gap — the proportion of people who need care and don’t receive it — is estimated at over 85%.

The reasons are layered: stigma, access, cost, and the absence of a culturally neutral vocabulary for emotional difficulty. But one of the most significant is simply that people don’t know where their symptoms sit on the clinical spectrum. Without a framework, the default interpretation is either “I’m fine, everyone feels this way” or “there’s something fundamentally wrong with me.” Both are forms of not getting help.

The PHQ-9 offers a third option: information.

The Five Severity Bands

1–4: Minimal depression. Subclinical. Monitor. 5–9: Mild. Symptoms present. Lifestyle and psychosocial support warranted. 10–14: Moderate. Clinical attention recommended. Therapy typically effective at this range. 15–19: Moderately severe. Therapy and/or medication discussion with a professional is recommended. 20–27: Severe. Prompt clinical assessment required.

The PHQ-9 also includes a question about frequency of thoughts about self-harm or death — question nine. A positive response to this question, regardless of overall score, is always clinically significant and warrants professional contact.

What a Score Is Not

A PHQ-9 score is not a diagnosis. It’s a signal. A moderate score on a screen means: this pattern of symptoms warrants professional assessment, not that a diagnosis is certain.

It also reflects a point in time. Depression fluctuates. A single score is one data point, not a permanent classification.

This Is Always Free

Charging for depression screening is indefensible. The PHQ-9 on this platform is free. The score includes full interpretation — what the clinical bands mean, what the research says about each range, and what appropriate next steps look like.
