Abstract
gogram, Minnesota Multiphasic Personality Inventory (MMPI) and Jenkins Activity Survey (JAS) were administered to 89 psychosomatic patients. The responsiveness of the dopaminergic system of the hypothalamo-pituitary gland was measured in all psychosomatic patients by examining the effect of bromocriptine on serum growth hormone levels. Patients were classified as either responders or non-responders based on their secretion patterns of serum growth hormone levels. Forty-two patients were classified as responders and 47 patients were classified as nonresponders. Comparisons of scores of Egogram, MMPI and JAS between responders and non-responders showed no differences between them. Then multidimensional scaling techniques were applied to the answers of Egogram and JAS. These analyses revealed the differences between responders and non-responders only on the answers of JAS. The result indicated that non-responders have characteristics of hyperadaptation and an active coping style toward stress. In this study, the difficulty of measuring the behavioral characteristics related to the dopaminergic dysfunction using Egogram and MMPI was suggested. On the other hand, the usefulness of JAS to measure these characteristics was indicated.
