• Patient health questionnaire 4 item total score
• The PHQ-4 is different -- although the total score (which ranges from 0-12) can be used, it is really a combination of the PHQ-2 depression scale (described above) and the GAD-2 anxiety scale (from the parent GAD-7 anxiety scale). Thus, another way to look at it is a 0-6 depression subscale and a 0-6 anxiety scale. It is clearly different than either the PHQ-9 or the PHQ-2
