Scoring the PHQ-9

Depression severity is calculated by assigning scores of 0, 1, 2, and 3 to the categories of 'not at all'; 'several days'; 'more than half the days' and 'nearly every day' respectively. The total score for the nine items scored ranges from 0 to 27.


'Major depressive syndrome' is likely if questions number '1' ('little interest or pleasure in doing things') or '2' ('feeling down, depressed, or hopeless') and five or more of questions '1' through '9' score at least '2' ('more than half the days'). Count question number '10' if answered.


'Other depressive syndrome' is likely if questions number '1' or '2' and two, three, or four of questions numbered '1' through '10' score at least '2' ('more than half the days'). Include question number '10' if answered. The sum of the first two questions is sometimes used as a quick guide to the likely presence of depression. the 'PHQ-2' as this is called, gives a score between zero and six. A score of three or more warrants further investigation.


A diagnosis cannot be made using the PHQ-9 alone; a professional clinical interview should consider the possibility of physical causes, drug use, any manic / hypomanic episodes and normal bereavement reactions.


Score Severity Possible Approaches (include user preference)
00 – 04 None or minimal None required
05 – 09 Mild Active monitoring; lifestyle change, low-intensity therapy, self-help, peer support
10 – 14 Moderate Support, active monitoring, antidepressant or psychological therapy
15 – 19 Moderately Severe Antidepressant and / or psychological therapy
20 – 27 Severe Antidepressant and psychological therapy - consider collaborative management
