Performance of children with traumatic brain injury on the Cognitive Assessment System

Children and adolescents with traumatic brain injury (TBI) were compared to a matched sample of neurologically normal children and adolescents on several measures of cognitive processing. Each of the children in the TBI group had experienced a closed head injury of moderate to severe magnitude. Participants in both the TBI (n = 22) and control (n = 22) groups ranged in age from 9 to 17 years and lived in the midwestern United States. They were all administered the Cognitive Assessment System (Naglieri & Das, 1997a). Children with TBI earned significantly lower scores in the domains of Planning and Attention than the matched control group. Within-group comparisons showed that the TBI group s Planning and Attention scores were significantly lower than their Simultaneous and Successive scores. The results are consistent with previous literature demonstrating poor performance on measures of attention and executive functions among children who have experienced TBI.
