Should linking replace regression when mapping from profile-based measures to preference-based measures?

Peter M Fayers et al. Value Health. 2014 Mar.

Abstract

Background: Profile instruments are frequently used to assess health-related quality of life and other patient-reported outcomes. However, preference-based measures are required for health-economic cost-utility evaluations.

Results: Although regression-based approaches are commonly used to map from profile measures to preference measures, we show that this results in biased estimates because of regression to the mean.

Conclusions: Linking (scale-aligning) is proposed as an alternative.

Keywords: linking values; mapping functions; patient-reported outcomes; preference-based measures; profile instruments; scale-aligning; test equating.
