Intervention Project to Increase Adherence to Colorectal Cancer Screening in Barcelos/Esposende

The intervention will consist in two text messages (one and two weeks after received the screening test, respectively), an automated non-human call or a call made by the administrative assistant (three weeks after received the screening test), and a phone call made by a physician (four weeks after received the screening test)

The control group will not be subjected to any interventions to increase the adherence to screening.
