The SDFI (Sasang Digestive Function Questionnaire) is developed to measure type-specific digestive function-related symptoms for identification of Sasang type and pathophysiological symptoms based on the previous studies (1).
The 21-item SDFI has three subscales, such as SDFI-Digestion, SDFI-Appetite, and SDFI-Eating pattern, and its validity and reliability was test repeatedly (2).
* The SDFI is protected under the Intellectual Property Law in Korea. So if you want to use, you should contact us in advance.
