Patient Health Questionnaire-4 (PHQ-4)

The PHQ-4 questionnaire can be used to quickly assess to what extent you might be experiencing anxiety and/or depression. You can complete the questionnaire in your head or online. Think about how often you experience the feelings listed in the questions. Question 1 and 2 ask about signs of anxiety, while questions 3 and 4 ask about depression. If your answer to any of these is 'nearly every day', that is a sign you might be anxious or depressed. For more information, see our video on identifying anxiety and depression.
