Treatment for DID consists primarily of individual psychotherapy and can last for an average of five to seven years in adults. Individual psychotherapy is the most widely used modality as opposed to family, group or couples therapy. The main goal for treatment is the integration of the separate personality states into one cohesive, unified personality, unless the person with DID is not ready or motivated to work with trauma. Psychotherapy for dissociative disorders often involves techniques that help work through the trauma that triggers dissociative symptoms. Treatment may include the following stages: uncovering and "mapping" the alters or parts; treating the traumatic memories and "fusing" the alters; and consolidating the newly integrated personality.
