| Abstract |
In September 2008, a questionnaire on preventive
care and the value of risk reduction was administered to the LISS panel. Panel
members were asked about their participation in preventive care programs
available in the Netherlands
(flu shots, cervical cancer tests, mammograms, STD tests and the use of aspirin
for the prevention of heart disease). In addition, they were asked about their previous experience with the disease and
prevention, whether they were invited to participate in the free program, the
motivations behind their participation decision, the actual or expected costs
of the intervention, risk factors that might influence their individual risk of
disease, and their perceptions of the risks they face with and without
preventive care.
Panel members were
asked a number of subjective probability questions, including the risk of
developing a particular disease and the risk of mortality. The questionnaire also had an experiment to
investigate the role of framing. Some people were asked about the probability
of survival and others were asked about the probability of death. Also the order
of the subjective probability questions was randomized.
Finally, visual aids were used to help people to interpret and express
small probabilities: One third of the respondents answered the probability
questions in a normal answer box, one third received a digital scale to provide
their answer, and one third was presented a number-line with a magnifier,
making it easier to choose very small probabilities. |
