History of psychology
Branches of psychologyThe Diagnostic and Statistical Manual of Mental Disorders (DSM) is published by the American Psychiatric Association and provides diagnostic criteria for mental disorders. It is used in the United States and in varying degrees around the world, by clinicians, researchers, psychiatric drug regulation agencies, health insurance companies, pharmaceutical companies and policy makers.
The DSM has attracted controversy and criticism as well as praise. There have been five revisions since it was first published in 1952, gradually including more disorders, though some have been removed and are no longer considered to be mental disorders. It initially evolved out of systems for collecting census and psychiatric hospital statistics, and from a manual developed by the US Army. The last major revision was the fourth edition ("DSM-IV"), published in 1994, although a "text revision" was produced in 2000. The fifth edition ("DSM-V") is currently in consultation, planning and preparation, due for publication in May 2012.[1] The mental disorders section of the International Statistical Classification of Diseases and Related Health Problems (ICD) is another commonly-used guide, used more often in Europe and other parts of the world. The coding system used in the DSM-IV is designed to correspond with the codes used in the ICD, although not all codes may match at all times because the two publications are not revised synchronously.
Many mental health professionals use this book to determine and help communicate a patient's diagnosis after an evaluation; hospitals, clinics, and insurance companies also generally require a 'five axis' DSM diagnosis of all the patients treated. The DSM can be used to establish a diagnosis or categorize patients using diagnostic criteria. The DSM may also be used in mental health research. Studies done on specific diseases often recruit patients whose symptoms match the criteria listed in the DSM for that disease. An international survey of psychiatrists in 66 countries comparing use of the ICD-10 and DSM-IV found the former was more often used for clinical diagnosis while the latter was more valued for research.[2]
