PHQ-9 Depression Screen
The Patient Health Questionnaire (PHQ-9) is the most widely used screen for depression: nine questions, one for each symptom in the diagnostic criteria, about the last two weeks. Your score (0-27) is placed in the standard severity bands and compared with US adults from the National Health and Nutrition Examination Survey 2017-2020 (N = 8,276).
This is a screening questionnaire, not a diagnosis. A high score says your answers resemble those of people who often have the condition; only a clinician can tell whether you do.

Almost done!
Two optional questions, asked once: your age and sex let the results be broken down by who took the test.
Sex as at birth; gender as you identify. Languages you grew up speaking; several are fine, separated by commas. Leave blank anything you would rather not say.
