How are 'psychological disorders' classified?

Psychological disorders are classified primarily using standardized diagnostic manuals, such as the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) and the ICD-10 (International Classification of Diseases, 10th Revision). These manuals provide criteria and guidelines for diagnosing mental health conditions, encompassing a wide range of disorders and ensuring consistency in diagnosis across different professionals and settings.

Utilizing the DSM-5 or ICD-10 is essential because these tools are based on extensive research and clinical observations, creating a comprehensive framework that helps mental health practitioners categorize disorders effectively. This categorization enables accurate diagnosis, treatment planning, and communication among healthcare providers, leading to better patient care.

In contrast, relying solely on personal interviews or specific assessments like neurological tests or family histories is insufficient for the comprehensive classification of psychological disorders. While these methods can provide valuable information as part of a broader assessment, they do not encompass the full range of criteria and dimensional analysis necessary for a formal diagnosis based on established standards.
