Diagnosis of functional psychoses. Comparison of clinical and computerized classifications.

The results of a comparison between the clinical diagnoses of 115 probands with functional psychoses, made on the basis of careful clinical history-taking, interviewing and examinations, and those made by computerized evaluation (CATEGO) on the basis of the present state examination (PSE) were presented. The clinical diagnoses of the project psychiatrist and the provisional classification resulting from the application of the CATEGO program to the PSE symptom profiles were in an overall concordance of 82%. In a second step the 20 cases with differences in diagnoses were reevaluated on the basis of the full history and psychopathology and a syndrome checklist was completed. This reevaluation led to a practically full diagnostic agreement.
