[Crohn disease--addiction--neurosis: comparison of ego functions]

25 neurotic patients, 25 alcoholics, and 25 patients suffering from Crohn's disease were rated with a german adaption (by Streeck) of Bellak's Ego Function Assessment scales. Crohn's disease patients showed personality characteristics similar to those of patients suffering from psychosomatic illnesses. Ego function disturbances could be found with respect to Introspection as a subfunction of Reality Testing, Creativity and Capacity for Abstraction as a subfunction of Thought Processes. The results indicated a remarkable heterogeneity of the Crohn's-patient group as well as possible influences of gender-specific personality differences in that group.
