Profile instruments are frequently used to assess health-related quality of life and other patient-reported outcomes. Preference-based measures are required for health-economic cost-utility evaluations. 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. Linking (scale-aligning) is proposed as an alternative.
