DSM-5 Self-Exam: Dissociative Disorders
Psychiatric News
Volume 48 Number 23 page 1-1

Major changes in dissociative disorders include (1) derealization is included in the name and symptom structure of what previously was called depersonalization disorder; (2) dissociative fugue is now a specifier of dissociative amnesia rather than a separate diagnosis; and (3) the criteria for dissociative identity disorder are changed to indicate that symptoms of disruption of identity may be reported as well as observed, and gaps in the recall of events may occur for everyday and not just traumatic events. Also, experiences of dissociative identity disorder in some cultures are included in the description of identity disruption.

The questions below are from DSM-5 Self-Exam Questions: Test Questions for the Diagnostic Criteria, which may be preordered from American Psychiatric Publishing at http://www.appi.org/SearchCenter/Pages/SearchDetail.aspx?ItemId=62467. The answers and rationales are posted at http://www.psychnews.org/pdfs/DSM-5_Self_Examination_QandA_17.pdf. The book, available in February 2014, contains 500 questions for all the categories of psychiatric disorders and includes Section III. The questions were developed under the leadership of Philip Muskin, M.D., a professor of clinical psychiatry at Columbia University College of Physicians and Surgeons. APA members may purchase the book at a discount.
