[In what way can the clinical usefulness of the Wechslers-Bellevue test for general knowledge be improved for the testing of neuropsychiatric patients? An attempt at revalidation (author's transl)].

Questions related to general knowledge were adapted to the mental capacity of neuropsychiatric patients by means of regrouping and suitable modifications. The sequence of items according to the degree of difficulty, enables a more profitable use of the Wechsler-Bellevue test, since the questions relating to general knowledge need not begin with Question No. 1. The general knowledge subtest was changed into a psychopathometric method by means of an item analysis. In this manner, it is more adequately adapted to the mental capacities of neuropsychiatric patients. Moreover, irregular distribution of data which have not yet been evaluated and classified, is avoided, so that the intellectual performance of the patient can be explored in a fairer manner than before.
