Proposed a 120‐item version of the 208‐item Category Test for adults. When the test protocols of 70 diverse S s including 18 with definite brain impairment were scored for both the standard and short form, a very high degree of correlation ( r = .95) was found, which suggests that the two forms are nearly equivalent. The application of cut‐off scores (normal vs. brain impaired) resulted in only 3 S s changing classifications from the standard to the short form, with 2 of those changes in the correct direction. A savings in administration time of about one half was observed.
