About this questionnaire

The PHQ-9 (Patient Health Questionnaire-9) was developed by Drs. Spitzer, Williams, Kroenke and colleagues. Doctors use it widely to screen adults for depression.
The questions, answers and scoring on this page are the official text, without changes. The levels follow the official instruction manual.
The questionnaire is a screening tool, not a diagnosis. Only a doctor can diagnose depression, after a full assessment.

Questions 1 to 9 score 0 (Not at all), 1 (Several days), 2 (More than half the days) or 3 (Nearly every day). The total is from 0 to 27. The last question is not scored.

Score	Result	Meaning
0–4	None-minimal	You have few or no symptoms of depression. The official manual proposes no treatment action for this range.
5–9	Mild	You have mild symptoms of depression. The official manual proposes watchful waiting and repeating the PHQ-9 at follow-up.
10–14	Moderate	You have moderate symptoms of depression. The official manual proposes a treatment plan, considering counselling, follow-up and/or medication.
15–19	Moderately severe	You have moderately severe symptoms of depression. The official manual proposes active treatment with medication and/or psychotherapy.
20–27	Severe	You have severe symptoms of depression. The official manual proposes starting medication immediately and, if daily life is severely affected or treatment does not help, a quick referral to a mental health specialist.
