The Preliminary Study on the Coincidence between Sasang Constitutional Analysis Tool β-version and Expert of Sasang Constitution

The Preliminary Study on the Coincidence between Sasang Constit utional Analysis Tool β-version and Expert of Sasang Constitution Eun-Su Jang, Hee-Jeong Jin, Jun-Hyung Do, Si-Woo Lee, Jong-Yeol Kim. Korea Institute of Oriental Medicine 1. Objectives In Sasang constitutional medicine, it has been known that diagnosing Sasang constitution correctly is mostly important. We had developed an Integrated Sasang Constitutional Analysis Tool (SCAT) β-version using face, voice, body shape and questionnaire before. The purpose of this study is to suggest whether SCAT β-version is reliable or not. 2. Methods We collected 371 subjects from 6 oriental medical clinics. We analyzed the Sasang constitutional diagnostic results using Kappa and coincidence rates between experts in Sasang constitution and SCAT β-version which was developed on the basis of face, body shape, voice and characteristics and symptom questionnaire data. 3. Results The agreement rates between SCAT β-version and experts was 69.3% in total, and 73.2%, in Taeeumin, 70.8% in Soeumin, and 56.9% in Soyangin in detailed. The Kappa was 0.510 (p value<.000). There was an increasing trend of agreement rates and kappa value corresponded to increasing constitutional probability. When The constitutional probabilities were changed from below 40%, to over 40%, 50%, 60%, the agreement rates corresponded from 50.8% to 79.5%, 91.4%, 95.7% respectively.
