ABSTRACT
Erzigkeit's accelerated syndrome test is used to determine the severity of functional psychoses. This test, by which the proficiency level of a subject may be ascertained, should be evaluated in dependence upon the subject's age and general level of intelligence. To correct for these quantities, the accelerated syndrome test includes combined standards for four age and three IQ levels (12 tables of standards). The quality of correction should be empirically verified here. A sample of sixty-three medical students (this sample was characterized by a very high degree of homogeneity in that the students were of the same age and also had the same IQ's) were used to show that the standardization of age and IQ in the accelerated syndrome test allows functional psychoses to be far more readily recognized than when no consideration is given to these variables. Classification by degrees of disorder should also be much more convincing than without the use of differential standardization.
