A questionnaire was administered to 42 subjects completing a one-year cancer chemoprevention trial (response rate = 69%, n = 29). The questionnaire assessed subjects' 1) previous study participation, 2) perceived benefits/barriers of participation, 3) likelihood of participating in future trials, 4) willingness to pay out-of-pocket expenses for trial participation, and 5) interest in post-trial continuation of the drug.
