Communicating probabilistic information to cancer patients : in there noise on the line ?
The objective was to examine the way that cancer patients translate verbal descriptors of probability into numerical estimates.
A list of words commonly used on consent forms to describe the likelihood for benefits or risks of therapies was provided to 100 cancer patients.
Two formats, paper/pencil or computer, were used to provide the list of words.
Two methods, magnitude estimation and linear analogue scaling, were used to obtain probability estimates for each word.
In addition, two scenarios were developed to study « context effects » on numerical interpretations of verbal descriptions of probability.
All patients provided numerical values for the words on two occasions, separated by one week, and two interviewers collected the data.
