In contrast to conventional approaches in which it is important to treat the cause of the dissociative symptom, this case of dissociative identity disorder is distinctive in the paradoxical process. Although the child personality of the patient (alter personality) was thought to be a kind of fake, it has been kept in therapy. The process in which her child personality had been one-sidedly exaggerated and emphasized dialectically led the patient to internalize the dissociated personality and have a self-relationship in the end.
