Abstract

According to the considerations at the beginning of this symposion we tried to apply the polydiagnostic approach (PDA) (the simultaneous application of various diagnostic criteria to one and the same population under study) to a sample of patients with delusional syndromes. The motives for this procedure were: 1. the concept of axial syndromes has been developed in several cohorts of delusional patients and 2. the delusional symptomatology itself is one of the main pitfalls in many of the widely used diagnostic systems. Productive symptoms have a central position, e.g. in the FRS, whose validity underwent criticism especially in the last years (Carpenter et al., 1973), but which on the other hand are used on a world-wide scale and provide the basis for schizophrenia diagnosis in several diagnostic systems as for example Taylor et al. (1978), in part RDC (Spitzer et al., 1978) and ICD-9 (WHO 1978). The assumption that incongruencies between different diagnostic systems can be distinctly demonstrated in a sample of delusional patients, seems to make this diagnostic group especially suitable for the application of the PDA.
