Abstract
Background
Correlation between reports of children and parent for health-related quality of life (HRQOL) is not well studied. This study aims to assess the degree of agreement between child self- and parent proxy-rated HRQOL and to identify factors associated with discordance at baseline and during follow-up in Taiwanese children with chronic kidney disease (CKD).
Methods
This study includes pediatric patients aged 5–18 years with confirmed CKD. Participants completed the generic version of the Pediatric Quality of Life Inventory (PedsQL) at baseline and every 6 months during follow-up. Child–parent agreement on HRQOL reports was assessed using intraclass correlation coefficient (ICC). Multivariate regression models were used to determine factors associated with child–parent discordance.
Results
Of the 112 child–parent dyads included in the analysis, 97 dyads with 640 patient visits were assessed in 4.5 years. Children reported higher total scores on the physical and psychosocial domains as compared to their parent proxies. ICC was low (< 0.5) for the psychosocial domain and moderate for the physical health domain at initial assessment and slightly increased for the physical health (0.62) and for school functioning (0.51) during follow-up. Development of mineral bone disorder/anemia (β, 11.75 [3.77–19.72]) and proteinuria (β, 8.48 [1.15–15.81]) in the follow-up were associated with increased discordance in school functioning, and fathers with chronic disease were associated with increased discordance in social functioning (β, 4.21 [0.68–7.74]).
Conclusions
Parent proxy consistently estimated lower PedsQL score compared to self-reports of children. Child self-rated psychosocial health domains should be evaluated whenever possible to better elucidate treatment outcome over time.
