- Arm II (standard information intervention): Patients receive overview information as in arm I. The patients then use a website listing of the four existing CRC screening test options along with graphical representations. They are allowed to interact with this web page to view basic or more information about any or all of the tests. The program informs them when all the information has been viewed. At this point, patients are asked to choose which test they would prefer to receive from a list of existing test options, as in arm I.
