ScreenTalk to Improve Colorectal Cancer Screening Uptake Among First-degree Relatives of Patients: a Study Protocol

Participants in intervention group will receive the ScreenTalk intervention consisting of 3 modules:(1) a measurement module, (2) an algorithmic tailoring module, and (3) an open di-alogue module. All participants will be required to complete 3 modules within 1 month. If the intervention group does not undergo CRC screening at the follow-up time point, the system will repeatedly provide tailored communication intervention to further enhance the CRC risk perception of FDRs based on the current evaluation results. The primary outcome (uptake of CRC screening) will be measured at 3 months post-intervention (T1), 6 months post-intervention (T2), 9 months post-intervention (T3) and 12 months post-intervention (T4).
