Comparison of AMP system and comprehensive psychopathological rating scale with regard to contents

Using a sample of 170 patients the psychopathological contents of the AMP system and the Comprehensive Psychopathological Rating Scale (CPRS) were compared by canonical correlations. The nine primary AMP scales predict 86% of the variance of the three CPRS scales. 64% of the variance of the nine AMP scales is explained by the CPRS scales. The secondary scales are nearly equivalent. The univariate analysis showed that all AMP scales with the exception of the 'hostility syndrome' and the 'catatonic syndrome' correlate highly with one of the psychopathological CPRS scales.
