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.
