Abstract:
In this Commentary, we compare two categorizations of a dermatological health-related quality-of-life (HRQoL) instrument, the Skindex-29. One was created on the basis of an anchor-based method, the other on a distribution-based method. Differences between the two classifications are discussed, emphasizing the importance of the interpretability of HRQoL measures.
