Parent and child ratings of child behaviour following mild traumatic brain injury.

BACKGROUND

Mild traumatic brain injury (mTBI) in children is most commonly associated with parent-reported child behaviour problems. The extent to which parent and child ratings align is unknown.

OBJECTIVES

To examine differences in child behaviour and patterns of recovery over the first 12 months following mTBI based on parent and child self-report.

METHODS

Ninety-nine children (8-15 years) with mTBI and one of their parents completed the Behavioural Assessment Scale for Children - version 2 to assess child hyperactivity, anxiety and depression at baseline, 1, 6 and 12 months post-injury. Differences between ratings from parents and children were evaluated using Bland-Altman limits of agreement analyses. Child recovery over time was examined using mixed models repeated measures analyses.

RESULTS

Parent and child ratings for child hyperactivity, anxiety and depression differed significantly at baseline and these differences remained constant at each follow-up. Parents tended to report more child hyperactivity, anxiety and depression. Over time, parents and children reported fewer child hyperactivity and anxiety problems.

CONCLUSIONS

Parents and children have poor agreement in ratings of child behaviour yet there is general agreement in patterns of recovery in the year following mTBI. Findings show the importance of considering both parent and self-report of child behaviour.
