Abstract
1. From the view point of the roles and manifestations of anxiety in psychosomatic disorders, there seems to exist two types of disorders. The one is the disorder in which signs and symptoms of the disease can be understood predominantly as the direct neurophysiological manifestions of anxiety itself. The other is the disorder in which signs and symptoms of the disease can be understood mainly as the manifestations of avoidance response from the anxiety-provoking lifesituations. 2. From the behavioral point of view, the treatment of the former type of disorders can be usually successfully carried out by using the procedures based on the principle of reciprocal inhibition or systematic desensitization. For the treatment of the latter type of disorders, on the other hand, the principles of operant procedures and social skill training should be the main therapeutic strategy. 3. In this paper, some illustrative cases of these types of psychosomatic disorders were presented to verify the above-mentioned basic principles of the methods for behavioral understanding and treatment of psychosomatic disorders in general.
