Abstract
So taken. On the 2 occasions 65% and 70% of patients were able to scale intensity words with an internal consistency of r ≥ 0.90. Eleven (55%) patients met this criterion on both occasions. The percentage of patients meeting the internal consistency criterion for unpleasantness descriptors was much lower, 25% and 40% on the 2 occasions. For patients who met the internal consistency criterion for intensity words there was very high test-retest stability for the group scale values of the intensity words. There was no evidence that the level of psychological distress was associated with ability to scale unpleasantness words. Intelligence was positively related to the ability to scale intensity descriptors. ∗Correspondence to: Dr. S.J.
