The Anxiety Sensitivity Index (ASI) is a 16 item scale containing items specifying different concerns someone could have regarding their anxiety. The Anxiety Sensitivity Index-3 (ASI-3) is an 18 item scale.
The subject rates each item by selecting one of five phrases: “very little” (0 points), “a little” (1 point), “some” (2 points), “much” (3 points), and “very much” (4 points). No items are reversed coded.
Sum all 18 items to get ASI3 Total; 6 items per subscale

- ASI3 Cognitive Concerns = 14,18,10,16,2,5
