The theory of psychotherapy was established by a single case study. Even though it was lack of generality, it must have been a basic important role in the clinical field. Under the above assumption, the therapist had only one client as a case study that couldn't be well adjusted and had many conflicts because he not only had many complexes, but could'nt recognize complexes themselves. The chief problems to the client who complained the psychosomatic symptoms and anxieties were assumed dependency and inferiority complex. In order to recognize these complexes, therapist had 30 interview section with him. The major goal of therapy was the maturation by which the ability of recognition of complex was obtained. The measurement of effect as to whether the client was matured or not was the advancement of schoolwork result and the progress of sociometric rating. Besides, the therapist exerted all the possible effort in interpreting psycological problems was found in every section of interview. The result of this therapy was known as a full progress in academic credits and in the development of human relationship as same as therapist's expectation. In this study, the therapist used the psychoanalytic insight therapy and the client-centered therapy as the therapeutic method for the client.
