Objective:
To describe the relationship between health-related quality of life (HRQL) as measured by utility when elicited from parents and their children with chronic illness.
Study Design And Setting:
We enrolled families of children admitted for cancer chemotherapy and those attending outpatient rheumatology, hemophilia and bone marrow transplantation clinics. Children in grade 6 or higher were included. The child's HRQL was rated by parent and child using the Standard Gamble (SG), Visual Analogue Scale (VAS), Time Trade-Off (TTO), and Health Utilities Index Mark 2/3 (HUI2 and HUI3).
Results:
22 families were included. The mean parent SG was 0.92 +/- 0.09, which was similar to the mean SG elicited from their children of 0.92 +/- 0.10. The parent and child SG were moderately concordant (ICC=0.64, 95% CI=0.30, 0.83; P=.0005). In contrast, TTO scores were not concordant (ICC=0.14, 95% CI=-0.29, 0.53; P=.3), with parents (mean TTO=0.77 +/- 0.31) rating HRQL worse than children (mean TTO=0.92 +/- 0.11; P=.04). Similarly, the mean parent HUI2 of 0.82 +/- 0.22 was lower than the child HUI2 of 0.95 +/- 0.07; P=.02 and HUI2 were not concordant (ICC=0.11, 95% CI=-0.35, 0.53; P=.3) between parents and children.
Conclusion:
Parents and children rate HRQL similarly according to SG, but parents rate HRQL significantly worse using TTO and HUI2.
