“Therapeutic self” is the foundation that every healthcare professional should acquire. It is an important theme in professionalism education, which aims to educate learners about the attitudes needed to be a good doctor. It is assumed that as learners gain “resonance (subjective estimation) “ and “objective estimation” , they will be able to improve patient-doctor interactions and achieve a good balance with therapeutic self.　In this article, firstly we explain the concepts associate with therapeutic self, then we introduce the strategy aimed at cultivating the therapeutic self in professionalism education: Through fieldwork training in a community, we aim to make the students more aware of the importance of the trust relationship between doctors and patients. We also aim to raise awareness about how healthcare professionals should be. An objective assessment of the therapeutic self was done using conversation analysis.
