The study aims to recruit 60 Spanish speaking individuals who identify as Latinos, are 18 years or older and attend the Saint Thomas More (STM) Church in Chapel Hill. Study participants will be asked to attend an educational session at STM Church during which their baseline knowledge on colorectal cancer (CRC) and willingness to participate in cancer clinical trials (CCT) will be assessed through a questionnaire in Spanish. Following this, participants will watch three educational videos on CRC in Spanish. After watching the videos, CRC knowledge and willingness to participate in CCTs will be reassessed. Thirty +/- 7 days after participation in the educational session, participants will be invited back at STM Church in order to complete a follow-up questionnaire assessing CRC knowledge, willingness to participate in CCTs and perceived barriers preventing Latinos from participating in CCTs. Twenty of the 60 recruited participants will be asked to participate in a qualitative one-on-one interview aimed at identifying barriers preventing Latinos from participating in CCTs.
It should be noted that cancer is the leading cause of death in the United States (US) Latino community, with CRC accounting for 10% of this overall mortality. Despite this, Latinos suffer from disparities in access to care, cancer screening, treatment, and representation in CCTs. In fact, although Latino individuals are among the largest and fastest growing communities of color in the US, currently comprising 18.7%, their representation in CCTs remains low. This is of concern because: 1) advances arising from trials with limited Latino representation may not be applicable to the Latino population, and 2) decreased Latino participation in CCTs may delay Latino access to novel therapies in a timely fashion. The investigators conducting this study believe that low cancer-specific health knowledge may be impacting Latino representation and willingness to participate in CCTs and can be addressed through culturally and linguistically appropriate community-based educational interventions. Latino CCT underrepresentation is a multifaceted phenomenon and bidirectional barriers at the physician-, healthcare system-, and patient-level are significant contributors. Therefore, understanding the multiple driving forces and barriers is essential to identifying potential targets for improvement.
This pilot project aims to address the Clinical and Translational Science (CTS) roadblock of underrepresentation of Latinos in cancer clinical trials (CCTs) through a community-based, culturally, and linguistically appropriate educational intervention aimed at increasing health knowledge on a specific cancer. Colorectal cancer (CRC) will be the "use case" and the church will be the venue for Latino recruitment. This project will lead to the identification of novel Latino-perceived barriers to CCT enrollment, which will be applicable in other fields of medicine aiming to increase Latino CCT enrollment. The investigators believe that one barrier to recruitment for CCTs is low health education, specifically regarding cancers affecting the community, such as CRC, a commonly diagnosed cancer in the US Latino population. Therefore, the hypothesis that an increase in health knowledge in Latinos on a specific cancer mediates a change in their willingness to participate in CCTs will be tested. To do this, three educational CRC videos in Spanish will be created. The first video will review CRC symptoms, the second video will review CRC risk factors while the third video will provide information on CRC facts, screening, treatment and CCTs. In addition, a translated, non-validated questionnaire based on 3 sub-scales from 2 CRC knowledge questionnaires previously validated in English will be developed and pilot tested. Therefore, the Specific Aims of this Pilot Project are to:
To achieve these aims, recruit 60 Latino, Spanish speaking attendees of the Saint Thomas More (STM) Church in Chapel Hill will be recruited. The study will consist of three Study Days:

Adverse Events were monitored from the time of signing informed consent through study completion, up to 30 days for participants involved in the educational video only and up to 60 days for those who participated in the qualitative interviews.
The participants in the study completed questionnaires pre- and post- an educational video. The risks associated with this study were minimal and the participants were not at risk for mortality or serious adverse events as a function of participating in this study. Because this study investigated the impact of an educational intervention, All-Cause Mortality and Serious Adverse events were not monitored or assessed.
