Generalized Anxiety Disorder (GAD 7)

The result provided by the GAD 7 calculator is aimed at revealing whether an anxiety disorder is present and to what degree.

Each of the 7 questions can be rated from 0 to 3 on the scale introduced above. Therefore, the overall GAD 7 score ranges between 0 and 21, 0 meaning no anxiety and 21 meaning severe anxiety.

The following are the possible scores from this test:

0 - 4   No or little anxiety

5 - 9   Mild anxiety disorder

10 - 14   Moderate anxiety disorder

15 - 21   Severe anxiety disorder
