Abstract
Constructed a short screening device to measure organic brain dysfunction, suitable for literate and non-literate populations. A battery that consisted of 8 tests and 22 scoring variables was administered to 65 brain-damaged Ss and 65 normal Ss. The two groups were matched on a person-to-person basis with respect to age, sex and years of schooling. Stepwise multiple regression technique was used to develop a procedure for discriminating organics from normals. At a selected cut-off point the battery could discriminate between organics and normals with only 6% misclassification of normals and 16% misclassification of organics. The classificatory system was validated further against a fresh sample of 33 Ss. The battery proved to have satisfactory discriminatory capacity.
