PHQ-9, a nine-question depression scale

Depression symptoms check

Nine short questions about the last two weeks, taken unchanged from the PHQ-9, a widely used questionnaire for depression symptoms. The result is a symptom level, not a diagnosis. One question asks about thoughts of self-harm; if you answer yes, you will see where to get help straight away, before anything else.

Who it is for

Adults aged 18 and over who want to see how strong their low mood or depression symptoms have been over the last two weeks. The age limit is our rule for this service, not a statement about whom the scale was validated for.
