Anxiety and depression quick screen (PHQ-4)
Four questions for a quick look at anxiety and depression symptoms over the last two weeks.
About this scale
The PHQ-4 combines the PHQ-2 depression screen and the GAD-2 anxiety screen and takes under two minutes. If either subscale reaches 3, take the full Depression check or Anxiety check to see how strong the symptoms are. It is a screen, not a diagnosis.
