Psychoanalysis, behaviorism, and the humanistic movement have, in the latter years of the twentieth century, been joined by a fourth psychological force, Transpersonal psychology. This study utilized a Qualitative methodology, Social-Constructivist orientation, Case Study design, and Dual Narrative format to explore the feasibility of utilizing a transpersonal approach in a case of Dissociative Identity Disorder. Sub-units of the investigation were (a) the treatment of Dissociative Identity Disorder by traditional, psychoanalytic/medical model psychotherapy, (b) the functions of the altered states of consciousness within the client\u27s personality system, (c) the functions of the Internal Self Helper in the integration of the client\u27s fractured self, and (d) the theoretical orientation of the therapist and its impact upon the treatment process
