A method of assessing the anxiety of an individual developed by Norman L. Corah, an American behavioural scientist, in 1969. The scale consists of four questions about different dental situations. Each question is scored from 1 (not anxious) to 5 (extremely anxious) so the range of possible scores is 4 to 20. Scores of 15 or more indicate profound anxiety. See also modified dental anxiety scale.
