PHQ-9 Depression Screening

Assess the frequency of common depressive symptoms experienced during the last two weeks. The questionnaire takes only a few minutes and is scored entirely inside your browser.

This questionnaire is a screening tool.

It does not provide a diagnosis and should be interpreted together with clinical history, functional impact and professional assessment.

Over the last two weeks

How often have you been bothered by the following problems? Select one response for every question.

01 Little interest or pleasure in doing things
02 Feeling down, depressed or hopeless
03 Trouble falling asleep, staying asleep, or sleeping too much
04 Feeling tired or having little energy
05 Poor appetite or overeating
06 Feeling bad about yourself — or that you are a failure or have let yourself or your family down
07 Trouble concentrating on things, such as reading the newspaper or watching television
08 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 more than usual
09 Thoughts that you would be better off dead or of hurting yourself in some way

Impact on daily functioning

How difficult have these problems made it to work, take care of things at home, or get along with other people?

This response provides clinical context but is not included in the numerical PHQ-9 score.
