Standard Scale for Syndrome Differentiation of Yin Deficiency Syndrome

Study Overview
=================
Brief Summary
-----------------
An version of the standard scale for syndrome differentiation of Yin Deficiency Syndrome is not available yet for Chinese medicine. The aim of this study is to develop and validate the standard scale for syndrome differentiation of Yin Deficiency Syndrome. The study is divided into two steps. The first step is to develop the standard scale for syndrome differentiation of Yin Deficiency Syndrome through expert consultation (Delphi method). The second step is to apply the scale in the participants and find out the diagnostic cut-off value of the scale by comparing it with the gold standard.
