The relationship between parental report on the BRIEF and performance-based measures of executive function in children with moderate to severe traumatic brain injury.

The Behavior Rating Inventory of Executive Function (BRIEF) is a questionnaire that assesses parental observations of behaviors associated with executive function in children in the home environment. The current investigation examines the relationship between the BRIEF and individually-administered neuropsychological tests in children with traumatic brain injury. Forty-eight children with moderate to severe traumatic brain injury were administered the WISC-III and several performance-based tests of executive function (the Wisconsin Card Sorting Test, Trail Making Test Part B, verbal fluency), and a parent completed the BRIEF. Results indicate that the Metacognition Index from the BRIEF correlates with Verbal IQ, but none of the index scores from the BRIEF correlate with any of the performance-based tests of executive function. Results are discussed with respect to the ecological validity of standardized clinical neuropsychological tests of executive function.
