Comparison between Comprehensive Psychopathological Rating Scale (CPRS) and association for methodology and...

1. 5 AMP experienced raters examined 28 depressed and 22 psychotic patients. Symptoms were documented using the CPRS (preliminary German translation) and the AMP system. The two rating scales were compared from the raters point of views and using descriptive statistical methods. 2. The high number of CPRS symptoms showing significant correlations to AMP symptoms demonstrate a strong similarity between the two rating scales. 3. The AMP system gives a more differentiated and comprehensive picture of the psychopathology than the CPRS. 4. The CPRS seems to us to be easily communicable, mainly due to the exact description of the scale steps and the differentiation of reported and observed items. 5. For the measurement of changes during treatment half steps should be used to increase the sensitivity of the CPRS.
