The PHQ-9 is one of the most popular and widely used measures of depression. It's ten questions take just a couple of minutes to complete; give it a go and see how you score!

Over the last 2 weeks, how often have you been bothered by any of the following?
1.  Little interest or pleasure in doing things?
2.  Feeling down, depressed, or hopeless?
3.  Trouble falling or staying asleep, or sleeping too much?
4.  Feeling tired or having little energy?
5.  Poor appetite or overeating?
6.  Feeling bad about yourself - or that you are a failure or have let yourself or your family down?
7.  Trouble concentrating on things, such as reading the newspaper or watching television?
8.  Moving or speaking so slowly that other people could have noticed? Or the opposite - being so fidgety or restless that you have been moving around a lot more than usual?
9.  Thoughts that you would be better off dead, or of hurting yourself in some way?
10. If you identified any problems above, how difficult have these problems made it for you to do your work, take care of things at home, or get along with other people?

Scoring the PHQ-9

Depression severity is calculated by assigning scores of 0, 1, 2, and 3 to the response 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 rapid guide to the likely presence of depression. the 'PHQ-2' as this is called, gives a score on the range of zero to 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
