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.
使用莱顿强迫观念量表（LOI）以及从康奈尔医学指数的M - R部分选取的46个问题，对30名十二指肠溃疡住院患者和30名因溃疡性结肠炎入院的患者进行测试，以验证溃疡性结肠炎患者比十二指肠溃疡患者具有更多强迫观念特质这一假设。结果表明，尽管两组在强迫性人格特质方面差异不大，但溃疡性结肠炎患者对这些特质的担忧和关注明显更多。所测量的社会文化因素中，没有一个与所发现的差异相关，而其他研究表明这些社会文化因素会影响这些强迫观念得分。对两组之间莱顿强迫观念量表的各个项目进行分析发现，溃疡性结肠炎患者比十二指肠溃疡患者更优柔寡断，也更郁闷、更刻板且更守时，即这些特质传统上与强迫性人格类型相关。两组在康奈尔得分上没有差异。
