Background: In the field of psychology and psychosomatic medicine, Transactional Analysis (TA) was and developed by Berne and Dusey. Consecutively, egogram analysis has been prevalent by 5 egos including Critical Parent (CP), Nurturing Parent (NP), Adult (A), Free Child (FC) and Adapted Child (AC). In Japan, Tokyo University Egogram (TEG) has been used, and authors have continued egogram research for long.
Methods and Results: Subjects were 502 university students. They answered TEG questionnaire with the evaluation of the personality trait. Out of 29 personality pattern, 6 types were more than standard data. They are dependent, short-tempered, self-centered, conflict, solitude and pessimist types. During 10 years of our research, self-centered and solitude have been increasing, and good-hearted and playboy types have been decreasing.
Discussion: From current data, several tendency would be speculated: Lower NP seems to be a characteristic for modern university students. It may be related with a noticeable decline in overall morality among younger generations in Japan. Furthermore, the prevalence of internet in the world may influence of the behavior of young people. Not actual experience but information on the internet can make them refrain from active human relations to others. These results would be expected to become useful reference data.
