Formation and functions of alter personalities in dissociative identity disorder: a theoretical and clinical elaboration

Summary/Abstract: Dissociative identity disorder DID is a chronic complex psychiatric condition related to cumulative psychological traumatization in childhood. It is characterized by a marked disturbance of identity due to the presence of distinct personality states and repetitive dissociative amnesias which interfere with the continuity of the affected person’s autobiography. These personality states alter personalities recurrently take control of or influence the individual undermining one’s sense of self and agency. Although working with alter personalities is the hallmark of psychotherapy in DID, a detailed and specific clinical and theoretical psychopathology of alter personalities do not exist yet. Hence, the present paper addresses the formation and functions of alter personalities in DID. The hypotheses, proposals, and assumptions developed in this paper have been derived from experiences inintensive treatment of a very large number of patients with DID over more than two decades. The authors propose that the reconciliation between diverse perspectives about one’s internal world and external reality carried by various personalities is necessary for successful treatment of DID. The hallmark of dealing with alter and host personalities constitutes of the elimination of misperceptions of them about each other personality state and even about themselves.This requires an analysis of the missions and functions of alter personalities which are usually different than the perceived conceptualizations. This recognition usually increases the therapeutic alliance and even consent between the therapist, and alter and host personalities and decreases the duration of treatment. The present paper is a preliminary one on this subject and may serve as a basis both for further theoretical elaborations as well as for development of hypotheses in empirical research devoted to understanding the operations of human mind when exposed to stress in particular as well as the mechanisms of effective therapeutic interventions in those conditions.
