Increasing Colorectal Screening Uptake in Spouses of Patients With Colorectal Cancer Using a Randomized Behavioral Trial.

Background: Colorectal cancer (CRC) is one of the few cancers for which screening has been associated with better survival and morbidity, but screening uptake has been underexplored in spouses of existing patients with CRC. The objective of this study was to evaluate whether a brief, structured behavioral intervention delivered to spouses of patients with CRC in a colorectal clinical setting could increase fecal immunochemical test (FIT) uptake within 3 months of the study period.

Methods: This study was designed as a block randomized, unblinded, parallel trial conducted in the colorectal outpatient clinics of 2 public tertiary hospitals in Singapore from December 2017 to February 2023.
