Dissociative Identity Disorder in Psychiatric Inpatients

OBJECTIVE: The aim of this study was to replicate reports of a high rate of dissociative identity disorder in psychiatric inpatients. METHOD: Subjects were 100 randomly selected women, 16–50 years old, who had recently been admitted to an acute psychiatric hospital. Diagnoses were made by two interviewers through use of the Structured Clinical Interview for DSM-IV Dissociative Disorders. RESULTS: One percent (N=1) of the interviewed subjects had dissociative identity disorder. CONCLUSIONS: Contrary to previous studies, the authors found a low rate of dissociative identity disorder, perhaps because of the different methodology used.
