Dissociative identity disorder has been a matter of much controversy since it was first described in the academic literature during the 18th century. In the last two decades, the debate has ranged from sarcastic rejection to enthusiastic support, with little scientific data provided on either side. Recent research studies have endeavored to standardize assessment and quantify various aspects of the
disorder. Although much work remains to be done, the bulk of the data now support the existence of dissociative i dentity disorder and its continued usefulness as a diagnostic category.
