Jack Adams-Webber,
The Construing Person: According to [George] Kelly, anxiety is experienced
whenever one is confronted with events that are outside the range of
convenience of one's personal constructs, that is, one has no basis for
anticipating them. In short anxiety is being "caught with one's constructs
down."
Thesis Research ContributionI have developed a representation of patient values and a tailored elicitation procedure which forms the backbone of my thesis research.Utility Assessment on an Individualized BasisThe core of my Ph.D. thesis is a method for the collection of patient values on an individualized basis suitable for use in decision analysis models. The most unique aspect is that the representation of values is in the words of the patient. The elicitation is systematic and reproducible. It is basically a reconstruction of utility assessment using some fundamental utility assessment building blocks with a little systematic psychological domain methodology for eliciting dimensions of importance to an individual. You can download a 10 page pre-thesis paper in postscript or Word for W95 format from my ftp site or press here. The full thesis is available from the same site or press here. The defense was September 4th, 1998. You may view the web version of a presentation given February 5th, 1997, to my Oral Exam Committee for successful Ph.D. candidate qualification by clicking here .Resume'. You are welcome to read a more detailed description of my Career Goals and Objectives . Why, you ask, do we need to elicit the values of an individual?
I recently completed a pilot study in collaboration with Mark Davis,
MD, of the Beth Israel Deaconess Emergency Department in which we wanted
to find out whether patients would prefer to avoid severe disability as
a consequence of stroke or any increased risk of death. Current trends
in the use of clot dissolving drugs like tissue Plasminogen Activating
factor present us with a decision regarding just such a tradeoff. Studies
suggest that these drugs decrease the rate of long term disability significantly
if administered within a few hours of the onset of signs of stroke, but
at the cost of slightly increasing the risk that you might die with in a
few days. Understanding the preference of an individual in this case could
greatly aid decision making in choice of treatment. To no one's surprise,
we found a diversity in the values expressed in our structured interveiws.
To our surprise, however, we found more answers that were difficult to make
sense of than we expected, despite the authors of these answers being very
convinced of their preferences. I presented a talk that reviewed our findings
and the surprising rate of what is sometimes referred to as "discordant"
responses to values elicitation. The talk concludes that we need to find
better ways to systematically discover the way these patients think with
a few strategies based on the analysis of the data. Moreover, it justifies
the pursuit of my thesis research. You can browse
