ome clinical psychiatrists advocate the use of a test known as the Dissociative Experiences Scale (DES) to diagnose a condition referred to as Dissociative Identity Disorder (DID) (see Bernstein and Putnam, 1986, for the development of the DES). Patients diagnosed with DID are apparently prone to various symptoms, including amnesia, having two or more distinct personalities, and feelings of detachment from their bodies. The DES is a survey that attempts to monitor the frequency of certain associated traits, and on which high scores are consistent with DID.
