The GAD-7 consists of 7 questions based in part on the DSM-IV criteria for GAD and reflects the frequency of symptoms during the preceding 2-week period. The GAD-7 requires approximately 1-2 minutes to administer and for each symptom queried provides the following response options: "not at all," "several days," "over half the days" and "nearly every day" and these are scored, respectively, as 0, 1, 2 or 3.
