The DM-ID was designed as a companion to the DSM-IV-TR and aimed to assist clinicians to arrive at a more accurate DSM-IV-TR diagnosis for individuals with IDD. In 2013, the American Psychiatric Association published the DSM-5, thus necessitating revision of the DM-ID to incorporate the changes from the DSM-IV-TR to the DSM-5. The authors discuss the need for and development of the original DM-ID and changes in the DSM-5. The authors then offer insight into several chapters in the DM-ID-2 across the lifespan of individuals with IDD, looking at the changes in the DSM-5 and how these impact the ascertainment of mental disorders in individuals with IDD. %Z Copyright © 2016 The National Association for the Dually Diagnosed.
