Also, before the interventions and 3 months and 6 months after the interventions, refer to the experimental and control groups again and the champion questionnaire is completed and the mean score of health beliefs about colorectal cancer screening is determined and compared between the two groups. Intervention 2: Control group: In this group, any of the interventions of the intervention group is presented. If participation in this group recourse for a Fecal Immunochemistry test, the test will be done for them. At the end of the research, in order to comply with ethical issues, all the designed training materials will be provided to the control group.

Then, based on this generated list (BABA, ABBA, BAAB, BABA, AABB, ...), the subjects will be allocated into the intervention (B) or control (A) groups, Blinding description: In order to perform blinding, assistant researcher who collects data before and after the intervention, as well as statistician who analyzes the data, are blinded to the groups and the assignment of individuals in the groups.
