Step-by-step explanation:
DSM-V stands for Diagnostic and Statistical Manual of Mental Disorders, 5th Edition. This manual is published by the American Psychiatric Association and is widely used by clinicians and psychiatrists to diagnose and classify mental disorders. The DSM-5 includes comprehensive criteria for diagnosing various psychological disorders, such as substance use disorders, which involve a compulsive pattern of drug use often associated with physical and psychological dependence. Additionally, while the classification regarding personality disorders has been subject to debate, the DSM-5 retains the original ten categories with an alternate approach for classifying them as an emerging model. The changes and updates made in DSM-5 often reflect current research and the ongoing dialogue within the mental health community.
