title: A note on validating Wagstaff and van Doorslaer's health measure in the analysis of inequalities in health.
abstract: The aim of this note is to validate Wagstaff and van Doorslaer's approach of constructing a continuous health measure to be used in the analysis of inequalities in health. We calculate health concentration indices for Uppsala County in Sweden based on three different health status measures: health measured according to the WvD approach based on a self-assessed categorical health measure, health measured by the rating scale method, and health measured by the time trade-off method. The concentration index does not differ significantly for the three health status measures, and our results thus support the validity of the WvD method.
