Obsessional scores and subjective general psychiatric complaints of patients with duodenal ulcer or ulcerative colitis.

The Leyton Obsessional Inventory (LOI), together with 46 questions taken from Sections M-R or the Cornell Medical Index, were administered to 30 inpatients suffering from duodenal ulcer and to 30 patients admitted for ulcerative colitis to test the hypothesis that the latter have more obsessional traits than the former. The results indicated that although the two groups did not differ much in their obsessive personality traits, the ulcerative colitis patients were significantly more worried and concerned about them. None of the socio-cultural factors measured, which are known from other studies to influence these obsessive scores, was associated with the differences found. An analysis of the individual LOI items between the two groups showed that the ulcerative colitis patients were more indecisive, and also more morose, more rigid and more punctual than the duodenal ulcer patients, i.e. traits traditionally associated with obsessional personality types. The two groups did not differ on the Cornell score.
