Abstract
English
Pediatric Health-Related Quality of Life (HRQoL) as a measure of subjective well-being and functional capacity has gained increasing importance in recent years. However, the HRQoL of children and adolescents following a traumatic brain injury (TBI) has so far been insufficiently investigated, and conducting appropriate assessments in this population remains a challenge. This study compares the reports of children/adolescents and parents regarding the children's/adolescents’ HRQoL after a TBI using the newly developed, condition-specific questionnaire (QOLIBRI-KID/ADO). The severity of the TBI, the age of the children/adolescents, and the health status of the parents were examined as potential influencing factors on discrepancies between self- and proxy-reports. Three hundred data pairs from children/adolescents aged 8 to 17 and one parent were included in the study. Parent-child agreement, estimated using correlation coefficients, revealed low concordance between the reports. Discrepancies in the responses were analyzed using paired t-tests and Bland-Altman plots. The comparison revealed dimension-dependent significant differences. Parents tended to report lower HRQoL scores than the children/adolescents themselves. Overall, a large degree of individual variability in the discrepancies was observed—particularly in the dimensions of emotions and physical problems. Age of the children and adolescents and TBI severity, but not parental health status, were found to potentially influence the level of agreement between self- and proxy-reports. To date, pediatric TBI research has primarily relied on parent-reported HRQoL. However, given the overall low concordance values, the substantial variability in discrepancies between raters, and the dimension-, age-, and severity-dependent differences in reports from parents and children, the findings underscore the importance of prioritizing self-reports from children and adolescents.
