The study was designed to define and compare the professional and the
reasonable-person standards for provision of information to ovarian ca
ncer patients, and to determine if patient information priorities coul
d be anticipated by surrogate patients. Physicians treating ovarian ca
ncer patients, women treated for the disease, and well lay women imagi
ning themselves to have the disease used a visual analog scale to judg
e the importance of 57 questions that they might want answered before
treatment decisions are made. On the basis of median importance scores
, all groups judged questions relating to life expectancy as most impo
rtant. Overall, judgments of the patient groups agreed well with one a
nother; doctor-patient agree ment was significant but smaller than bet
ween patient agreement. Predicting an individual's judgments from his/
her group, however, was very poor for all groups. Life experience and
demographic characteristics rarely improved our ability to predict an
individual's judgments.
