The study examined the biopsychological features of Yin-Yang personality using a revised version of the Sasang Personality Questionnaire (rSPQ), finding that the rSPQ demonstrated robust psychometric properties and accurately captured the distinctive psychological characteristics of Yin-Yang. The results highlighted the organized subscale structure and clinical validity of rSPQ, providing a foundation for cross-cultural psychology and integrative medicine research.
Background: The biopsychological, pathological and physical characteristics of Yin-Yang (Eum-Yang in Korean) have been suggested using Sasang Personality Questionnaire (SPQ), however, the revision of SPQ is required for escalating its clinical use and multidimensional study on Yin-Yang. Methods: 274 university students were recruited to complete the SPQ, candidate items of revised SPQ (rSPQ) along with the Temperament and Character Inventory (TCI). After selecting rSPQ items using Item Analysis and Explorative Factor Analysis, its psychometric property was examined using Confirmatory Factor Analysis, Pearson's correlation and t-test. The biopsychological features of Yin and Yang personality groups based on rSPQ total score were illustrated with the TCI using ANOVA and Profile Analysis. Results: The behavior, cognition and emotion subscales of 15-item rSPQ had robust psychometric construct and showed distinctive psychological characteristics of Yin-Yang. The rSPQ-total score was correlated positively with SPQ-total (r = 0.644, p < 0.01) and TCI Novelty-Seeking (r = 0.398, p < 0.01), and negatively with TCI Harm-Avoidance (r = -0.364, p < 0.01). And, the Yin personality group (34.45 +/- 10.36 and 46.82 +/- 12.27) has significantly different scores in Novelty-Seeking and Harm-Avoidance compared to Yang personality group (43.2 +/- 9.1 and 36.53 +/- 10.78). Yin and Yang personality groups showed distinctive TCI subscale profiles as shown in previous studies. Conclusion: The current study showed the organized subscale structure and clinical validity of rSPQ for Yin-Yang personality, and it would provide foundation for East-West cross-cultural psychology and integrative medicine.
