Only persons initially screening by FIT (through a Rural Cancer Prevention Center service program) will be eligible for study participation. The objective is to test a social media-based intervention designed to promote annual repeat colo-rectal cancer screening using the Fecal Immunochemical Test (FIT) among person who have taken the FIT test once before. 220 men and women (50 to 75 years of age) will be recruited and randomly assigned to either the intervention condition (monthly social media contact) or a control condition (standard of care reminder for repeat testing one month before the annual test is due). The dependent variable will be whether volunteers requested and retuned a FIT kit with 60 days of the annual due date (one year from their initial screening).
