The Diagnostic Manual – Intellectual Disability: A Clinical Guide for Diagnosis of Mental Disorders in Persons with Intellectual Disability (2nd ed.; DM-ID-2) offers clinicians who work with individuals with ID a convenient, easy-to-use reference for applying DSM-5 diagnostic criteria to their clients.

Improved outcomes for individuals with co-occurring intellectual/developmental disability (IDD) and mental illness depend upon effective psychiatric treatment.  Effective treatment requires an accurate psychiatric diagnosis.  Obtaining that accurate psychiatric diagnosis for individuals with IDD has been, and remains, very challenging. 

The DM-ID-2 Clinical Guide was developed to facilitate an accurate psychiatric diagnosis in persons who have intellectual disabilities and to provide a thorough discussion of the issues involved in reaching an accurate diagnosis.  The DM-ID-2 Clinical Guide provides state-of-the-art information concerning mental disorders in persons with intellectual disabilities.  Grounded in evidence based methods and supported by the expert-consensus model, DM-ID-2 Clinical Guide offers a broad examination of the issues involved in applying diagnostic criteria for psychiatric disorders to persons with intellectual disabilities.  The DM-ID-2 Clinical Guide is an essential resource for every clinician who works with individuals with a dual diagnosis (IDD/MI).


DM-ID-2 Workbook

​Dr. Rozemarijn (Rosie) Staal

The DM-ID 2 Workbook was developed as an accompaniment to the second edition of the Diagnostic Manual-Intellectual Disability (DM-ID 2) in order to provide clinicians such as physicians, psychologists, social workers, counselors, and therapists with a comprehensive method to make an accurate diagnosis of mental health in individuals who have an intellectual disability (ID). The DM-ID 2 Workbook provides a structured interview format that focuses on identifying observable signs of mental illness, particularly where symptom presentation and diagnostic criteria differ in individuals with ID. In doing so, this ensures that all symptoms of mental illness that may otherwise be misdiagnosed or overlooked are incorporated into the diagnostic decision and that all relevant diagnostic options are considered prior to making a diagnosis. In summary, following the structured diagnostic method outlined in the DM-ID 2 Workbook will assist clinicians to make the most accurate diagnosis of mental illness in cases where individuals have an intellectual disability.
