The primary difference between the DSM (Diagnostic and Statistical Manual of Mental Disorders) and the ICD (International Classification of Diseases) lies in their origin, scope, and purpose.
Here's a breakdown:
DSM vs ICD: Key Differences
| Feature | DSM | ICD |
|---|---|---|
| Producer | A single national professional association. | A global health agency with a constitutional public health mission. |
| Scope | Primarily used for mental health diagnosis in the U.S. | A comprehensive classification system that covers all diseases, including mental disorders, used globally for healthcare reporting. |
| Primary Focus | Primarily focused on diagnosing and classifying mental disorders | Aims to reduce the disease burden of all diseases, including mental disorders, in countries worldwide. |
| Geographic Use | Primarily used in the U.S. | Used internationally in many countries |
| Development | Focuses on the needs and context of mental health in the United States. | Developed with a global public health mission in mind, considering the needs of various healthcare systems worldwide. |
In More Detail:
-
The DSM:
- Published by the American Psychiatric Association (APA).
- Primarily a diagnostic manual focused specifically on mental disorders.
- Serves as the standard reference for mental health professionals in the United States and is also used in many other parts of the world.
- It provides specific criteria for each mental disorder, assisting clinicians in making consistent and reliable diagnoses.
- Example: The DSM is the reference used by U.S. psychologists and psychiatrists to classify a person's condition as Major Depressive Disorder, or Generalized Anxiety Disorder.
-
The ICD:
- Published by the World Health Organization (WHO).
- A classification system that includes all diseases (both physical and mental), not just mental disorders.
- It is the international standard for health data reporting and statistics.
- The focus for mental and behavioral disorders classification is to help countries to reduce the disease burden of mental disorders.
- It is used in many countries to track and report diseases for morbidity and mortality statistics.
- Example: The ICD is the standard reference for classifying conditions like Diabetes, Heart Disease, or Cancer. It also contains codes for mental disorders.
Practical Implications:
- For Clinicians: Mental health professionals in the U.S. primarily use the DSM for diagnosing mental disorders, but they may also use the ICD for billing and reporting purposes.
- For Researchers: Both systems are utilized by researchers to conduct studies on mental health disorders.
- For Public Health: The ICD provides crucial data for tracking the prevalence of mental health conditions on a global scale. According to the reference provided, the WHO's primary focus for the mental and behavioral disorders classification is to help countries to reduce the disease burden of mental disorders.
Summary of Key Differences:
- Origin: The DSM is a product of a US-based association, while the ICD is produced by a global health agency.
- Focus: The DSM's focus is on classifying mental disorders, while the ICD covers all disease classifications.
- Use: The DSM is mainly used in the U.S., while the ICD is used worldwide for reporting health statistics.
In essence, while both systems aim to classify and categorize conditions including mental health, they have different origins, focuses, and utilizations in the healthcare landscape.
