Product Description: The second edition of this dictionary has been fully revised and updated and substantially expanded by the addition of further entries. All the terms and vocabulary from the field of psychiatry have been reviewed and brought up to date by the inclusion of the terminology used in DSM-IV and ICD-10, as well as numerous other entries from this evolving area. The increasing standardization of scientific terminology in psychiatry has thus been taken account of. Overall, around 4000 terms from the fields of psychology and psychiatry have been added, bringing the total to around 35,000 in each language. In addition to numerous words and terms from psychology and psychiatry in general that have been added, particular importance has also been placed on including new terminology from the areas of biological psychology, personality psychology, methodology and computer-based assessment, as well as relevant terms from fields such as computing and the Internet. At the same time, corrections and changes of usage since the previous edition have been included and some terms which have become obsolete have been removed. The new German spelling and orthography is used throughout. Also included are explanations and translations of more than 1000 of the most common abbreviations used in the fields of psychology and psychiatry.
