Egogram is a sort of psychological scales theoretically based on Transactional Analysis. Tokyo University Egogram (TEG) published in 1984 was a questionnaire with high reliability and validity. Since then, it has been widely used in various fields such as medical care, education, and industry. The second edition of TEG was published in 1993 after three years of basic studies. In this study, we investigated the usefulness of TEG 2.0 for its clinical application by means of examining correlations with other psychological tests; Cornell Medical Index (CMI), Profile of Mood States (POMS) and Self-rating Depression Scale (SDS). The statistical methods used were as follows : 1. Calculating and testing correlation cofficients among 5 scales TEG-CP (Critical Porent), NP (Nurturing Parent), A (Adult), FC (Free Child) and AC (Adapted Child) and the scores of the other psychological tests. 2. Profiles outlined by 5 scores of TEG are interpreted as total ego states. Thus, we applied multivariate analyses to deal with 5 scales simultaneously. Canonical discriminant analysis with CMI as the Class was conducted on CP, NP, A, FC and AC as the independent variables. Multiple regression analysis with POMS and SDS as the dependent variables was performed on CP, NP, A, FC and AC as the independent variables. The results of these analyses were summarized as follows : 1. Correlation coefficients : (a) There was a significantly positive correlation between CMI and AC. (b) Regarding subscales of POMS, there found some significantly positive correlations with CP, FC and AC; CP and Anger-Hostility, FC and Vigor, AC and Tension-Anxiety, AC and Depression, and AC and Confusion. (c) There was a significantly positive correlation between SDS and AC. 2. Multivariate Analyses : (a) The canonical discriminant analysis with CMI as the class showed that AC had a significantly positive canonical coefficient. It was suggested that one with higher score on AC was more neurotic. (b) The multiple regression analysis with POMS as the dependent variable showed that AC and CP had a significantly positive partial regression coefficient. It was suggested that one with higher scores on AC and CP showed more negative feelings. (c) The multiple regression analysis with SDS as the dependent variable showed that AC and CP had a significantly positive partial regression coefficient and that A had a relatively small but significantly negative partial regression coefficient. It was suggested that one with higher scores on AC and CP and lower score on A showed more depressive feelings. Consequently the usefulness in clinical application of the second edition of TEG was confirmed by these results of this study.
