[The new international psychiatric classification system, ICD-10. II. New classification systems in psychiatry].

The different interpretations of the concept of "mental disease" and the absence of an etiopathogenetic plane in the area of mental disorders led to the creation of descriptive (phenomenological) classifications of mental disorders. Their main representatives are the American diagnostic and statistical manual of mental disorders, DSM-III, its revised version DSM-III-R and the new international classification of mental disorders iCD-10. Both systems use a common theoretical baseline and are to a considerable extent compatible. Typically they have a high reliability and low validity of diagnostic categories. Subsequent development of psychiatric classifications will be focused in particular on improvement of diagnostic validity. The international psychiatric classification was created in different versions for the purpose of specialized psychiatric care, primary care and for research.
