Willow LabsDepression Test
This free depression test uses the PHQ-9 — one of the most widely used and researched depression screening questionnaires in the world. It takes about two minutes, runs entirely in your browser, and asks for no sign-up and no email. Nothing you enter leaves your device.
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
What this test measures
The PHQ-9 asks about the nine symptoms clinicians look at when screening for depression — mood, interest, sleep, energy, appetite, self-worth, concentration, movement, and thoughts of self-harm — over the past two weeks. Your answers are summed into a single score from 0 to 27 that maps to a severity band, the same way it is used in primary care.
