Unlike the PHQ-9, clinicians use the GAD-7 to assess the severity of anxiety only. A clinical interview must be given to determine the presence and type of anxiety. The GAD-2 is a 2-question shortened version of the GAD-7 that uses the first two questions from the GAD-7. A total score that is greater than 3 indicates that a clinician should administer the full GAD-7 and conduct a clinical interview to assess the presence and type of anxiety disorder.
