The purpose of this study is to explore the experience of therapists and traumatized children. In this study, four therapists who had been engaged in child psychotherapy were interviewed using phenomenology as the research method. The study found that the therapist and the traumatized child were presented in a sequential manner in the treatment scene: "the conflict of his or her opposite-sex experience," "the presence of others and self-reality," and "the transformation of the self." From these three sequential changes, it is seen that therapists need to put themselves down before they can be close to the world of traumatized children. In addition, the results of this study provide a detailed description of the concept of "contained and containment" that therapists need to create "a space for healing trauma" for traumatized children and make recommendations for future practice.
