The paper is the second of a three-paper project. The first and third papers of this project are the following.

(1) Jansen, Sylvia J.T., Anne M. Stiggelbout, Peter P. Wakker, Thea P.M. Vliet Vlieland, Jan-Willem H. Leer, Marianne A. Nooy, & Job Kievit (1998), “Patient Utilities for Cancer Treatments: A Study on the Chained Procedure for the Standard Gamble and Time Trade-Off,” Medical Decision Making 18, 391-399. abstracts
This paper tests the practical feasibility of the utility measurement method by means of anchor levels, introduced in this project. It is found that patients can readily answer the questions required for the method, and that the data obtained have face validity.

(3) Wakker, Peter P., Sylvia J.T. Jansen, & Anne M. Stiggelbout (2004), “Anchor Levels as a New Tool for the Theory and Measurement of Multiattribute Utility,” Decision Analysis 1, 217-234. abstracts
This paper gives the theoretical justification of the utility measurement method by means of a preference foundation. Once anchor levels available, attribute utilities can be defined that incorporate any kind of interaction with other attributes.
