Patient Health Questionnaire-9 (PHQ-9)


Ask the patient: how often have they been bothered by the following over the past 2 weeks?

Little interest or pleasure in doing things?

Feeling down, depressed, or hopeless?

Trouble falling or staying asleep, or sleeping too much?

Feeling tired or having little energy?

Poor appetite or overeating?

Feeling bad about yourself, or that you are a failure, or that you have let yourself or your family down?

Trouble concentrating on things, such as reading the newspaper or watching television?

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?

Thoughts that you would be better off dead, or of hurting yourself in some way?

If you checked off any problems, 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?
