The Basic Rorschach Score was developed by Buhler as a means for facilitating standardization of the Rorschach test on different population groups. In 1945 she gave the Rorschach test to persons in 15 different diagnostic groups. The resulting test protocols were scored according to the usual Rorschach scoring determinants. Each determinant was then assigned a "weight." The mean of all these weights in a given protocol was given the name of Basic Rorschach Score. Buhler's principle finding was that the Basic Rorschach Score for each of the 15 groups represented in the study seemed to fall on a continuum, the highest positive Basic Rorschach Score being achieved by the normal group, the highest negative Basic Rorschach Score being achieved by the schizophrenic group. The Basic Rorschach Score, therefore, seemed a usable device for making diagnostic discrimination and also for accumulating standardization data.
