DSM IV The guideline that the American Psychiatric Association publishes which details what is and is not a psychiatric illness. Transsexualism and transvestism are included in the list of psychiatric disorders.
A manual produced by the American Psychiatric Association that catalogs mental disorders. The fourth edition (DSM-IV), published in 1994, characterizes pathological gambling as an impulse disorder and lists 10 characteristics of a pathological gambler. Five of the ten must be present for a diagnosis of pathological gambling to be made. In addition to its use in clinical assessments, the DSM-IV criteria have been used in studies to determine the prevalence of pathological gambling in the general population. The DSM-IV criteria are generally considered to be more conservative than those used in the South Oaks Gambling Screen (SOGS).
The Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, is the handbook used most often in diagnosing mental disorders. The International Statistical Classification of Diseases and Related Health Problems (ICD) is a commonly-used alternative internationally and includes all diseases, not just mental disorders. The DSM tends to be the more specific of the two.
