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.

As the author and of the DM-ID-2 Workbook, Dr. Staal is available to provide training, instruction and workshops to better support clinicians in their differential diagnosis.
