A shortened intermediate version of the Halstead Category Test.
An effort was made to determine whether the intermediate (ages 9-14) version of the Halstead Category Test (HCT) could be shortened to increase clinical utility without altering it's basic psychometric properties. The Long Intermediate Halstead Category Test was administered to four clinical groups. Statistics were conducted to verify that these groups did not relate differentially to the Category Test or other neuropsychological measures. Twelve shortened Category Tests were then extracted. The psychometric properties of these extracted shortened versions were compared to the long version and the three best were selected for further tests. These three shortened versions were then cross validated. Results indicated that the psychometric properties were similar across the shortened versions. The shortest version was there for chosen which best retained the characteristics of the original test.
