Classification systems

The DSM-5 and ICD-11 are both diagnostic systems used for classifying mental health disorders. However, there are some key differences between the two systems:

  1. Origin and Purpose: The DSM-5 is published by the American Psychiatric Association (APA) and is primarily used in the United States and other countries that follow the American system of psychiatric classification. The ICD-11 is published by the World Health Organization (WHO) and is used globally for diagnostic purposes, including data collection and disease management.
  2. Structure: The DSM-5 uses a categorical system, where disorders are separated into specific categories and individuals must meet specific criteria to be diagnosed with a particular disorder. The ICD-11 uses a dimensional system, where disorders are assessed along a continuum of severity and individuals can have a range of symptoms that are not restricted to specific categories.
  3. Diagnostic Criteria: The DSM-5 and ICD-11 have different diagnostic criteria for some disorders. For example, the DSM-5 includes specific criteria for the diagnosis of autism spectrum disorder (ASD), while the ICD-11 includes criteria for “autism spectrum conditions”.
  4. Number of Disorders: The DSM-5 includes more disorders than the ICD-11, but the ICD-11 covers a wider range of physical and mental health conditions.

It is important to note that the DSM-5 and ICD-11 are both continuously updated to reflect new research and knowledge about mental health disorders. It is crucial for mental health professionals to keep up-to-date with changes in diagnostic criteria and to use a combination of diagnostic tools and information to make accurate and appropriate diagnoses.
