The present study concerns a twin investigation on peptic ulcer from a psychosomatic point of view. Chapter I contains a brief survey of literature on the concept of psychosomatic illness and references to prior investigations with special regard to the personality in peptic ulcer. The importance of a distinction between gastric and duodenal ulcers in such investigations is stressed. In chapter 11, the various twin methods are mentioned, and the results obtained through them, for peptic ulcer, especially on heredity. References are made to Previously published studies of personality psychology in isolated pairs of twins with peptic ulcer. A description of the plan of the present investigation appears in chapter 111. The sampling was based on about I 7,600 consecutive patients with X-ray verified gastric or duodenal ulcers. Out of this primary sample, 120 pairs of twins of the same sex were extracted, 100 pairs of which were complete, i.e. with both twins alive. Out of these, 34 pairs were monozygotic. T h e field investigation supplied information on all these pairs of twins, through personal interviews and by questionnaire as well as from hospital records and interviews with relatives. All co-twins who reported any kind of gastric complaint, however untypical of peptic ulcer, were subjected to X-ray examination for manifest or previous gastric or duodenal ulcers. T h e main investigation was carried out on the complete monozygotic pairs, whose zygosity was carefully determined by serological analysis and who were subjected to a more detailed psychiatric interview to get an estimation of Personality and, if possible, of such factors of outward stress as might be of importance for the development of peptic ulcer. All co-twins were then X-ray examined. An experimental examination was also performed, using a number of serial tests, a closer description of which is to be found in chapter IV. The tests chosen were I ) the colour-word test to demonstrate the cognitive adaption to a conflict situation; 2 ) the rod-and-frame test, to objectify dependent traits of personality; 3) a so-called spiral-after-effect test which had previously Proved correlated to certain dimensions of personality; 4) a level-of-aspiration test; and 5 ) the meta-contrast technique which in previous investigations
