how many editions of the dsm are there
Diagnostic and Statistical Manual of Mental Disorders The DSM is now in its fifth edition, the DSM-5, published on May 18, 2013. The DSM evolved from systems for collecting census and psychiatric hospital statistics, and from a United States Army manual. Revisions since its first publication in 1952 have incrementally added to the total number of mental disorders, although also removing those no longer considered to be mental disorders.
Decision support system A decision support system (DSS) is an information system that supports business or organizational decision-making activities. DSSs serve the management, operations and planning levels of an organization (usually mid and higher management) and help people make decisions about problems that may be rapidly changing and not easily specified in advanceâ€”i.e. unstructured and semi-structured decision problems. Decision support systems can be either fully computerized or human-powered, or a combination of both.
