Comparison of three short forms of the Category Test.
The Category Test is a sensitive indicator of general cortical integrity, but requires an extremely long time for impaired subjects to complete. As a result, several authors have proposed abbreviated forms of the test. In this investigation, Study 1 compared three previously published short forms with the long form. Subjects were 100 consecutive adult referrals for neuropsychological assessment. Long-form protocols were rescored to yield the equivalent scores for the short forms. The 120-item short form appeared to be an excellent alternative to the long form. It correlated .981 with the standard 208-item Category Test, and had a comparatively small standard error of estimate. Study 2 compared the process of problem-solving by 52 additional subjects on this short form with the process on the equivalent items of the rescored protocols used to obtain the correlations. The processes appeared very similar.
