Nine men between nineteen and thirty-one years of age with diagnoses of peptic or duodenal ulcer confirmed by X-ray were organized in a therapeutic group. The anxiety and dependency at first displayed turned to group cohesion and hostility directed sometimes to group members but mostly to the therapist. Generally speaking, all participants showed a decrease in autoeroticism, better heterosexual adjustment, less acting out, and more ability to postpone gratification according to the requirements of reality. Recurrence of symptoms requiring dietary treatment was less in these men than average expectancy.
