Mapping the PedsQL™ onto the CHU9D: An Assessment of External Validity in a Large Community-Based Sample

Background Mapping algorithms have been indicated as a second-best solution for estimating health state utilities for the calculation of quality-adjusted life-years within cost-utility analysis when no generic preference-based measure is incorporated into the study. However, the predictive performance of these algorithms may be variable and hence it is important to assess their external validity before application in different settings.
