mortality*incidence*5-year survival*early stage
Physicians will be faced in scenarios about screening with information on mortality and 5-year survival, followed by information on mortality*incidence and 5-year survival*early stage in a random order.
- Number of Physicians (=Participants) Recommending the Screening [ Time Frame: 25 minutes (mean duration of the survey) ]The aim of the study was to learn how different medical cancer screening statistics would influence doctors' recommendation behavior and their effectiveness judgments of screening tests. For that reason the online survey study presented physicians with four different medical statistics (e.g., 5-year survival) within four successive scenarios and asked after each scenario whether they would recommend the screening to a (hypothetical) patient given the data. Options to answer are: Definitely yes, Probably yes, Probably no, Definitely no, Can't decide.
- Number of Physicians (= Participants) Assuming a Benefit of Screening [ Time Frame: 25 minutes (mean duration of the survey) ]Physicians are faced with four different medical statistics about the effect of screening (e.g., 5-year survival) within four successive scenarios and after each scenario asked whether they assume the screening to be beneficial given the statistical information. Options to answer are: yes, no, can't decide. If yes, then participants are further asked to describe this benefit by the following categories: Very large, large, moderate, small, very small.
