Introduction
Egograms, derived from Eric Berne's Transactional Analysis (TA), represent distinct ego states within an individual's personality. John M. Dusay, influenced by TA principles, developed a personality diagnostic tool based on this framework, which has since been applied across various domains. In recent years, Positive Psychology has emerged as a key applied discipline, contributing to the study of well-being. As part of this development, an egogram scale incorporating a positive perspective was designed to further support research and applications related to well-being. This scale was named the Positive Egogram, with the hypothesis that it would be associated with the positive dimensions of the Big Five personality traits.


Method
This study developed the Positive Egogram, consisting of 15 items representing five ego states: Critical Parent, Nurturing Parent, Adult, Free Child, and Adapted Child. A total of 2,987 participants (mean age = 46, SD = 15) completed an internet-based questionnaire. The data were analyzed using confirmatory factor analysis (CFA).


Results
The CFA supported a five-factor structure, showing a good fit to the data (CFI = .956, TLI = .943, RMSEA = .058, 90% CI = [.055, .062]). Cronbach's alpha coefficients ranged from .71 to .84, indicating satisfactory internal consistency. Mokken Scale Analysis also confirmed the reliability of the scale (Ht ≥ .49). The Positive Egogram showed significant positive correlations with the Big Five traits of Conscientiousness, Agreeableness, and Openness.


Discussion
The Positive Egogram demonstrated significant correlations with the Big Five traits of Agreeableness, Conscientiousness, and Openness, supporting the hypothesis that it reflects positive personality characteristics. Given its theoretical basis in TA, the scale shows construct validity. Future research should further investigate its association with well-being indicators and interpersonal relationship measures.
