What is the most recent edition of the guidebook for diagnosis of psychological disorders?

The most recent edition of the guidebook for the diagnosis of psychological disorders is the DSM-V, which stands for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Published by the American Psychiatric Association in 2013, the DSM-V provides standardized criteria for the classification and diagnosis of mental health disorders, serving as a critical tool for clinicians, researchers, and policymakers.

The DSM-V represents a significant update from its predecessor, the DSM-IV, with changes reflecting advances in research and changes in the understanding of mental health conditions. It incorporates a more dimensional approach to diagnosis, emphasizes the importance of a cultural context in understanding mental health, and includes new disorders and revised criteria for existing disorders.

While the ICD-10 and ICD-11 (International Classification of Diseases) are important diagnostic tools used globally, primarily by the World Health Organization, the DSM-V is specifically tailored for mental health in the United States and is widely referenced by mental health professionals in that context. The ICD-11 is the most recent international classification of diseases but includes both physical and mental health conditions, thereby serving a broader purpose than the DSM-V.
