Institute of Psychiatry and Medical Research Council

The Institute of Psychiatry was opened in 1923 as the medical school of the Maudsley Hospital, which was established in 1914 to treat the mentally ill. It was recognised by the University of London and changed its name to the Institute of Psychiatry in 1948, before becoming a school of King's College London in 1997. The Schedules for Clinical Assessment in Neuropsychiatry (SCAN) were developed under the auspices of the World Health Organization (WHO) and its International Classification of Diseases as a common set of standards to assess, measure and classify psychiatric disorders. The prototype was devised in 1980 and subsequent components such as training manuals, schedules, results of field trials and glossary were published up until 1998. SCAN is used as a classification and reference tool by psychiatrists and comprises a structured interview, encoding and computer programme to produce a standard diagnostic presentation.
