Toward a psychoanalytic understanding of multiple personality disorder.

The author suggests a developmental psychoanalytic frame from which to understand the clinical phenomenology of multiple personality disorder (MPD). Annihilation anxiety and fears of nonbeing are understood as central; they are seen as resulting from actual early traumatic impingements at key developmental periods. Alter "personalities" are conceptualized as functional delusional processes that serve to maintain self-cohesion. The alters are brought about through the subject's lack of capacity for illusion. Some therapeutic implications regarding a psychoanalytic stance are discussed.
