Free test · PHQ-4

Quick check for anxiety and depression (PHQ-4)

Four questions give a quick read on how much anxiety and low mood have weighed on you over the last two weeks. It is a screen, not a diagnosis: the score shows how much distress to take seriously and whether to look further.

Other versions of this test: PHQ-9 (9 questions) · PHQ-2 (2 questions) · GAD-7 (7 questions) · GAD-2 (2 questions)

What it measures

The PHQ-4 joins the GAD-2 (the first two questions, anxiety) and the PHQ-2 (the last two, depression). Each answer scores 0 to 3, for a total of 0 to 12: 0 to 2 is little or no distress, 3 to 5 mild, 6 to 8 moderate, 9 to 12 severe (Kroenke and colleagues, 2009; Löwe and colleagues, 2010). 3 or more on either pair is a positive screen for that pair.

This is not a diagnosis

Four questions only show how much distress there is, not what lies behind it. A doctor or therapist makes a diagnosis after a conversation.

What happens to your answers

Your score is calculated right in your browser. Your answers reach our server only if you ask for your result by email: we write the email and do not keep them.

How do I read the PHQ-4 for anxiety and for depression separately?

The first two questions are the GAD-2 and the last two are the PHQ-2. Add up each pair: 3 or more points on a pair is a positive screen for it. For a closer look, take the full version: Depression test
