I recently read an interesting article entitled Predictors of Neuropsychological Test Performance After Pediatric Traumatic Brain Injury. The authors were Jacobus Donders and Kelly Nesbit-Greene. The article investigated the influence of neurological and demographic variables on neuropsychological test performance, examining 100 9-16 year old children with traumatic brain injury. The investigation was conducted to determine the relative contributions of coma, neuroimaging findings, ethnicity, socioeconomic status and gender to variance and performance on the WISC-III, CVLT-C and Children’s Category Test. The researchers found, according to the abstract, both neurological and demographic variables contributed to performance on various WISC-III factor index scores as well as the CVLT-C. No evidence for a moderating effect of demographic variables was found, but speed of information processing mediated the effect of neurological and demographic variables on CVLT-C performance. The authors concluded that demographic variables have an incremental effect on the neuropsychological test performance of children with traumatic brain injury above and beyond the influence of injury severity.
