GAD-7 Scale Scoring Scores of 5, 10, and 15 are taken as the cut-off points for mild, moderate and severe anxiety, respectively. When used as a screening tool, further evaluation is recommended when the score is ten or greater. Evidence Using the threshold score of 10, the GAD-7 has a sensitivity of 89% and a specificity of 82% for GAD. It is moderately good at screening three other common anxiety disorders. Panic disorder (sensitivity 74%, specificity 81%) Social anxiety disorder Sensitivity 72% Specificity 80% Post-traumatic stress disorder Sensitivity 66% Specificity 81% Source Spitzer RL, Kroenke K, Williams JBW, Lowe B.
