PHQ-9 depression screener

The nine-question Patient Health Questionnaire, the most widely used screening measure for how much depressive symptoms have bothered you in the last two weeks.

This is a screening questionnaire, not a diagnosis. If you are in danger right now, contact your local emergency number or see the crisis page.

Over the last 2 weeks, how often have you been bothered by any of the following problems?

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

Your answers are scored for this one page and are not saved anywhere.
