title: Concurrent Validity of New Subscale Scores for the Booklet Category Test.
abstract: The Booklet Category Test (BCT) is a neuropsychological test of cognitive dysfunction that provides only one overall error score indicative of global impairment. It does not, however, delineate specific domains that might be impaired. The aim of this study is to concurrently validate 13 new BCT subscales using legacy instruments in patients with nonpenetrating traumatic brain injury (TBI). Eighty-nine patients with mild, moderate, and severe TBI completed a battery of neuropsychology tests. Partial correlations controlling for age were performed and there were significant correlations between the a priori selected scores from legacy measures of major cognitive domains and both BCT total errors and subscale scores. Additional analysis showed that several subscales were able to differentiate between performance levels on the legacy measures. Overall, our results showed that the subscales measured cognitive skills beyond global impairment, supporting the use of the BCT subscales in a population with TBI.
