title: [Scale formation in the AMDP (Society for Methodology and Documentation in Psychiatry) system].
abstract: The psychopathological and somatic symptoms documented by the AMDP-system on the admission of 1654 patients to the Psychiatric Clinics of the Universities in München und 659 patients in Berlin were factor analyzed. Eight factors could be extracted which describe the psychopathology on eight syndrome-scales. These factors could be cross-validated by factor analyses on random samples. In correspondence with the factors of the AMP-system the following syndromes were found: paranoid-hallucinatory, depressive, psycho-organic, manic, hostility, autonomic, apathy, obsessive-compulsive. For each of the 70 items which were associated with a factor we computed the percentage occurrence and item-scale-intercorrelations, for each of the eight syndrome-scales reliability-coefficients, intercorrelations and T-transformations. For further data-reduction second-order-factors were also computed.
