|Abstract: ||In health status index construction quantitative values for different states of
health are frequently obtained by presenting written descriptions to raters
whose values are elicited using one or more methods. In this study the authors
examined the influence of several aspects of this measurement process upon
the quantitative results obtained. They prepared a set of written descriptions of
health states, each state being described in both a standard point-form and a
narrative format. The narrative format was written in the first person singular,
and listed all symptoms or problems associated with the state, whereas the
point-form description included only the most severe symptom or problem.
Values for these states were elicited from a group of 64 patients using two
commonly employed methods, the standard gamble of Von Neumann and
Morgenstern and category rating. The results indicate that the type of scenario
presented to the rater and the sequence in which the methods of assessment
were used had a major influence on the results. This work indicates that there is
a need to examine systematically the process of obtaining quantitative values
before reliance can be placed upon the results.|
