Introjection and dissociative identity disorder: a case report

Summary/Abstract: Background: We wish to add to the current body of knowledge by investigating the different factors that play into the development of dissociative identity disorder, particularly trauma. DID in accordance with the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) is defined as a disruption in the identity by the presence of two or more distinct personality states, which often occurs after significant trauma. Ferenzci’s explored this with the theory on trauma-inducing neurosis. This theory was applied to our case presentation. Case presentation: We present a 19-year-old female patient who presented with active shifting of personalities was visualized in the clinical setting. This patient had experienced various forms of traumatic abuse, including sexual, verbal, physical, and even neglectful abuse from multiple family members. The patient developed dissociative states in which characteristics of the aggressors were mimicked. Conclusion: Ferenzci’s idea that traumatic situations likely trigger dissociative states during the early years in this patient was noticed in ⅗ personalities, while ⅖ did not support this claim. The other two dissociative states included the host, being the decisionmaker and leading figure, and also a euphoric character that exhibited regression when she felt comfortable. Although this case report supports some aspects of Ferenzci’s ideas on trauma-inducing neurosis, other theories must be explored to understand further the personalities that do not display aggressiveness.
