Diagnostic and Statistical Manual of Mental Disorders (DSM) Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is the standard classification of mental disorders used by mental health professionals in the United States. It is intended to be used in all clinical settings by clinicians of different theoretical orientations.
That's kind of what psychologists do with the DSM. The book acts as a guide to help them find the diagnosis, or name, of a mental disorder, such as schizophrenia, bipolar disorder, or autism. Each diagnosis is also given a number to help separate it and speed up referencing another professional's work.
