Development and Validation of the Digestive Function Assessment Instrument for Traditional Korean Medicine: Sasang Digestive Function Inventory

Abstract

Objective. This study was conducted for development and validation of the Sasang Digestive Function Inventory (SDFI) with type-specific digestive function-related symptoms for identification of Sasang type and pathological pattern. Methods and Materials. We selected questionnaire items for pathophysiological symptoms using internal consistency analysis and examined construct validity using 193 healthy participants. Test-retest reliability with a four-week interval as well as convergent validity was examined using the Nepean Dyspepsia Index-Korean (NDIK), Functional Dyspepsia-Related Quality of Life (FDQOL), Dutch Eating Behavior Questionnaire (DEBQ), and Body Mass Index (BMI). Results. The 21-item SDFI showed satisfactory internal consistency (Cronbach's alpha = 0.743) and test-retest reliability (r = 0.886, P < 0.001). Three extracted subscales, SDFI-Digestion, SDFI-Appetite, and SDFI-Eating pattern, explained 56.02% of the total variance. The SDFI showed significant (P < 0.001) correlation with total symptom score of NDIK, FDRQOL-Eating status, DEBQ-External Eating scale, and BMI. The SDFI score of the Tae-Eum (50.62 ± 8.05) type was significantly (P < 0.001) larger than that of the So-Eum (43.11 ± 11.26) type. Conclusion. Current results demonstrated the reliability and validity of the SDFI and its subscales, which can be utilized as an objective instrument for diagnosis of Sasang types and assessment of the type-specific digestive function.

Systematic review of type-specific pathophysiological symptoms of Sasang typology

“…The Sasang TSPS are type-specific clinical symptoms in digestion, sweat, sleep, urination, and defecation, and they are considered important clinical indices for diagnosis, intervention, and prognosis along with the biopsychological traits of each Sasang type 3, 8, 17. As for the underlying physiological systems, the Tae-Yang type is a person with strong sympathetic activation and weak anabolism and energy-storing characteristics, whereas the Tae-Eum type has strong anabolism and energy-saving and weak sympathetic activation.…”

Effects of a Herbal Medicine, Yukgunja‐Tang, on Functional Dyspepsia Patients Classified by 3‐Dimensional Facial Measurement: A Study Protocol for Placebo‐Controlled, Double‐Blind, Randomized Trial

“…The Nepean dyspepsia index (NDI) [33, 34] is a reliable and validated disease-specific index for FD, which measures symptoms and health-related quality of life. The Korean version of NDI (NDI-K) validated by Lee et al will be used [35, 36]. In this study, symptom-based questions, including the period, severity, and degree of distress of 15 symptoms, will be assessed using a 5- or 6-point Likert scale at baseline, 4 weeks, and 8 weeks.…”
