Final answer:
The Systematic classification in the DSM is the categorization of mental disorders to provide standard diagnostic criteria, evolving over time with DSM-5 being the latest version.
Step-by-step explanation:
The Systematic classification mentioned in the Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, refers to the categorization of mental disorders based on shared symptoms and characteristics. This classification aims to provide a common language and standard criteria for the diagnosis of mental disorders. The DSM has undergone several revisions, with the fifth edition (DSM-5), published in 2013, being the latest version. The DSM-5 has retained the ten original categories of personality disorders but has also introduced an alternate model for their assessment and diagnosis. This reflects the ongoing development in the understanding and treatment of mental health conditions. Additionally, criteria for the diagnosis of other psychological disorders, such as substance use disorders, are outlined, specifying the patterns of drug use that are indicative of a psychological dependency.
