Abstract
This article examines the prevalence and complexity of multiple personality disorder as well as the contributions that psychiatry and occupational therapy make in its treatment. The value of activity is that it serves as a nonverbal mediator of communication. Activities are also useful in helping the therapist to obtain a patient’s history, which is necessary for abreaction (i.e., the patient’s reliving and recalling of the original abuse). Abreaction is a precursor to the integration of the abusive memories into the patient’s current life.
