Description

Tokyo University Egogram (TEG) published in 1984 was a questionnaire based on Transactional Analysis with reliability and validity. It was constituted by 5 scales : CP (Critical Parent) , NP (Nuturing Parent). A (Adult), FC (Free Child), and AC (Adapted Child) . The second edition of TEG was published in 1993. The criterion validity of TEG 2.0 was confirmed by means of examining correlations with other psychological tests. In the present study, we attempted to investigate the clinical application of it. As the first step of investigation, we studied the psychological characteristics of controls and patients shown in TEG 2.0. 1 . The comparison between controls and patients with profile patterns judged by the definite criterion : 1) The patterns which were shown frequently in each group. 2) Percentage of adaptive or maladaptive patterns in each group. 2 . Multivariate analysis to deal with 5 scales : Profiles outlined by 5 scores of TEG are thought as total ego state. Thus, we applied multivariate analysis to deal with 5 scales simultaneously. Stepwise discriminant analysis with controls or patients as the class was conducted on CP, NP, A, FC, and AC as the independent variables. Then canonical discriminant analysis with two groups as the class was performed on selected scales by stepwise discriminant analysis out of 5 as the independent variables. The results of the procedure were summarized as follows. 1 . 1) Frequent patterns in each group by sex in the order of percentage : A dominant, N, and reverse N patterns were found in males of controls. N, fiat, and reverse N patterns were found in females of controls. Reverse N, low FC, and AC dominant patterns were found in males of patients. Low FC, N, and AC dominant patterns were found in females of patients. There are significant differences of percentages of TEG patterns between controls and patients of each sex. 2) Controls had a higher percentage of adaptive patterns than patients. Patients had a higher percentage of maladaptive patterns than controls. 2 . In male, the results showed that FC and CP had a significant canonical coefficient. It is suggested that one with lower score on FC and higher score on CP was significantly discriminated as patients. In female, the results showed that FC, CP, AC, and A had a significant canonical coefficient. It is suggested that one with lower score on FC and higher score on CP, AC, and A was significantly discriminated as patients. Consequently, clinical availability of the second edition of TEG was confirmed by these results of this study.
