Scoring the GAD-7

Anxiety severity is calculated by assigning scores of 0, 1, 2, and 3 to the response categories of 'not at all'; 'several days'; 'more than half the days' and 'nearly every day' respectively. The total score for the seven items scored ranges from 0 to 21.

Scores of 5, 10, and 15 represent cutpoints for mild, moderate, and severe anxiety, respectively

Using the threshold score of 10, the GAD‐7 has a sensitivity of 89% and a specificity of 82% for generalised anxiety disorder. It is moderately good at screening three other common anxiety disorders - panic disorder (sensitivity 74%, specificity 81%), social anxiety disorder (sensitivity 72%, specificity 80%), and post‐traumatic stress disorder (sensitivity 66%, specificity 81%). The sum of the first two questions is sometimes used as a rapid guide to the likely presence of anxiety. The 'GAD-2' as this is called, gives a score on the range of zero to six. A score of three or more warrants further investigation.

When screening for anxiety disorders, a recommended cutpoint for further evaluation is a score of ten or more. A diagnosis cannot be made using the GAD-7 alone; a professional clinical interview should consider the possibility of physical causes, drug use and any manic / hypomanic episodes.
