[Diagnostic reliability and validity of the PSE/CATEGO-system (author's transl)]

An unselected series of 100 psychiatric inpatient admissions were interviewed at admission by a psychiatrist using the German version of the PSE (Present State Examination), with a second psychiatrist as an observer. The diagnostic agreement between the two project psychiatrists was considerably higher than the agreement between clinicians and CATEGO, a computerised diagnostic system based on PSE data. The disagreements are discussed.
