DSM stands for “Diagnostic and Statistical Manual of Mental Disorders” and is published by the American Psychiatric Association, the professional organization representing United States psychiatrists. The DSM contains a listing of psychiatric disorders and their corresponding diagnostic codes. Each disorder included in the manual is accompanied by a set of diagnostic criteria and text containing information about the disorder, such as associated features, prevalence, familial patterns, age-, culture- and gender-specific features, and differential diagnosis. No information about treatment is included. The DSM is used by mental health professionals from a variety of disciplines and backgrounds in a wide range of settings, including clinical, research, administrative, and educational.
