Sustained attention in children and adolescents after traumatic brain injury: relation to severity of injury, adaptive functioning, ADHD and social background

Abstract

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.
