PHQ-9 Explained: What Each Question Means & How Scores Work
The PHQ-9 is one of the most widely used short questionnaires for checking in on low mood. This guide walks through what each question is really asking, how the scoring works, and what the levels tend to mean — in plain language.
Important to know first
A screening questionnaire is not a diagnosis. Only a qualified health professional can diagnose depression or any other condition. The PHQ-9 is a snapshot that helps you and a professional talk about what you're experiencing.
01The nine questions, one by one
Each question asks how often you've been bothered by a symptom over the past two weeks, on a 0–3 scale: not at all (0), several days (1), more than half the days (2), nearly every day (3).
Question 10 — functional impact
The MoodCheck test also asks how much these feelings have gotten in the way of work, home, or relationships. That question isn't added to the score — it adds context about how much the symptoms are affecting your daily life, which is exactly the kind of information that helps a doctor understand your situation.
02How scoring works
The nine questions are each scored 0–3, so the total runs from 0 to 27. Higher totals suggest more symptoms. MoodCheck groups the total into five levels:
| Total score | Level | What it tends to mean |
|---|---|---|
| 0–4 | None / minimal | Few or no symptoms of low mood in the past two weeks. |
| 5–9 | Mild | Some symptoms. Worth keeping an eye on and talking about if they persist. |
| 10–14 | Moderate | Symptoms are noticeable and may be affecting daily life. A conversation with a professional is a reasonable next step. |
| 15–19 | Moderately severe | Symptoms are having a real impact. Talking to a doctor or therapist soon is recommended. |
| 20–27 | Severe | Many symptoms, most days. Please seek professional support as soon as you can. |
Scores are a guide, not a verdict. Two people with the same score can feel very different, and how much the symptoms interfere with your life matters as much as the number.
