The 2-item Generalized Anxiety Disorder scale had high sensitivity and specificity for detecting GAD in primary care.

Description of test: GAD-7, a 7-item anxiety scale. Scores ranged from 0 to 21; scores of 5, 10, and 15 indicated mild, moderate, and severe anxiety symptoms, respectively. The first 2 items represent core anxiety symptoms, and scores on this GAD-2 subscale ranged from 0 to 6. The 2 items asked patients how often over the last 2 weeks they were bothered by (1) feeling nervous, anxious, or on edge and (2) not being able to stop or control worrying.
