Primary objective: To examine the relationship of child and family psychosocial variables and traumatic brain injury (TBI) severity as it relates to sustained attention (the Paediatric Assessment of Cognitive Efficiency, PACE).
Research design: Forty-two children and adolescents were recruited and participated in a 2 year longitudinal study to evaluate sustained attention using the computerized testing metric, PACE. More specifically, errors of omission (inattention) and commission (impulsiveness) were measured.
Main outcomes and results: Significant improvement on inattention and impulsiveness were observed over time. High pre-injury psychosocial adversity and low pre-injury adaptive functioning significantly predicted a greater number of inattention errors. Severity of injury predicted the reduction of impulsiveness. Moreover, omission errors immediately after TBI predicted later secondary attention-deficit/hyperactivity disorder (SADHD, ADHD that emerges after TBI).
Conclusions: Based on these findings, it is important to consider pre-injury child and family psychosocial characteristics in addition to severity of injury when predicting outcome of TBI in children.
