Final answer:
The standard classification of mental disorders in the U.S. is the DSM-5, published by the American Psychiatric Association. It is distinct from the ICD-10 and ICD-11, which are broader in scope and are published by the WHO for a global audience.
Step-by-step explanation:
The standard classification of mental disorders used by mental health professionals in the United States is DSM-5. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association, is the primary resource for diagnosing psychological disorders. The ICD-10 and its successor ICD-11, while used internationally for a variety of medical conditions, serve a more general purpose including the monitoring of morbidity and mortality rates globally.
The DSM-5 provides comprehensive criteria for diagnosing mental health conditions and includes detailed descriptions, symptoms, and other criteria necessary for clinicians to diagnose mental disorders. It is the culmination of years of research and clinical practice, incorporating changes and updates in the field of mental health. The ICD, on the other hand, is more generic and whilst it does cover mental disorders, it is used more broadly for all aspects of health conditions and is created by the World Health Organization (WHO).
