The Embree/Butler scoring system served as criterion for ascertaining brain dysfunction on the protocols of 100 subjects--50 had been diagnosed by health professionals as having brain dysfunction, and 50 had been diagnosed as having no brain dysfunction. In comparing the hospital's diagnoses with those of the Embree/Butler method, the data strongly supported the hypothesis that the Embree/Butler scoring system did effectively discriminate (chi square of 77.99 < .01) between those with organic brain syndrome (or cerebral dysfunction) and those with psychiatric classification. A point-biserial correlation was used to distinguish the relationship between diagnosis and the score. A cutoff score of above 14 produced the least false-negative or false-positive evaluations.
