ABSTRACT
Introduction : African Americans are disproportionately affected by mortality risk for colorectal cancer (CRC). This study aimed to determine the most effective educational approach of four study arms that enhances the likelihood of pursuing subsequent CRC screening, and to identify the associated factors. Methods : Age-eligible adults (N = 2877) were recruited to participate in a cluster randomized control dissemination and intervention implementation trial entitled Educational Program to Increase Colorectal Cancer Screening (EPICS). The project began in May 2012 and ended in March 2017 (the implementation phase lasted for 36 months). Educational sessions were conducted through 16 community coalitions that were randomized into one of four conditions: website access (to facilitator training materials and toolkits) without technical assistance (WA-TA), website access with technical assistance (WA+TA);in-person training (provided by research staff and website access) without technical assistance (IP-TA);and in-person training with technical assistance (IP+TA). A follow-up to determine participant CRC screening was conducted three months later. Results : Compared to the WA+TA intervention group the two groups of IP+TA and IP-TA indicated significantly higher odds for obtaining CRC screening (OR (95% CI): 1.31 (1.04,1.64);p-value= 0.02 and 1.35 (1.07,1.71);p-value= 0.01, respectively). Though sociodemographic factors were not significantly associated with pursing subsequent CRC screening, the post intervention cancer knowledge increased significantly among the study participants. Conclusions : The importance of in-person interactions, local coalitions and community contexts may play a key role for successfully increasing CRC screening rates among African Americans as reflected through this study. The integration of telehealth and use of other virtual technologies to engage the public in research have increased since the COVID-19 pandemic and should be assessed to determine their impact on the degree to which in-person intervention are significantly more effective when compared to solely web assisted.
