Abstract
The Peek-Quast and Hain scoring systems for the Bender Gestalt Test (BGT) were employed in an attempt to discriminate 142 brain-damaged patients from 120 control patients. While 12 of the 30 individual signs and the Peek-Quast and Hain BGT scores differentiated between the groups at a better-than-chance level of significance, diagnostic errors were so frequent as to preclude the BGT's being useful for individual diagnosis. It was suggested that the use of the BGT may increase the number of diagnostic errors when the base rates are low. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
