Abstract
PURPOSE: To explore the characteristic quality of health profiles of children with paediatric acquired brain injury (pABI), and to investigate whether improvement in executive function (EF) following cognitive rehabilitation is associated with improvement in health-related quality of life (HRQOL). METHOD: A study of secondary endpoints in a blinded, parallel-randomised controlled trial with children (ages 10-17 years) with pABI and executive dysfunction. Data was obtained from 73 children-parent dyads. Explorative analyses were conducted comparing baseline with 8-week post-intervention, and 6-month follow-up data. Outcome measures included the EQ-5D-Y-3L health dimensions and the visual analogue scale (VAS). RESULTS: At baseline and 6-month follow-up, mean (SD) VAS were 76.22 (17.98) and 79.49 (19.82) on the parent-report, and 77.19 (16.63) and 79.09 (17.91) on the self-report, respectively. Comparing children who improved EF to those who did not improve/worsened, no significant improvement was found for the VAS (parent-report) over time (BRIEF-BRI: F = 2.19, p = 0.12, BRIEF-MI: F = 2.23, p = 0.12) for either group. A significant main effect by group was found for BRIEF-MI (F = 4.02, p = 0.049), but no time*group interaction (F = 0.414, p = 0.662). CONCLUSION: The children and their parents reported only minor problems across EQ-5D-Y-3L dimensions and evaluated overall health as relatively good. Participants with a clinically significant change in the metacognitive aspect of EF had higher HRQOL. Cognitive interventions aiming to ameliorate deficits in EF in pABI may be beneficial to improve HRQOL.
