– Corresponding categories for anxiety disorders, as defined by the classification systems of the ICD‐9 and the DSM‐III‐R, were compared in a selected sample of 114 outpatients. An unequivocal category‐to‐category correspondence could not be demonstrated for any diagnosis. Anxiety states in ICD‐9 were closely related to generalized anxiety and panic disorder in DSM‐III‐R, and most patients diagnosed as phobic according to ICD‐9 one of the specific phobia diagnoses of DSM‐III‐R. To some degree, diagnostic discrepancies were caused by coexisting symptoms of phobia, panic attacks and/or generalized anxiety within patients. A new technique is introduced to adjust corresponding proportions according to base rate differences.
