Brief summary

The purpose of this proposal is to test the efficacy of a patient-centered, tailored message intervention delivered via virtual technology for increasing colorectal cancer (CRC) screening within guidelines among racial/ethnic minority and rural patients. This protocol focuses on the clinical portion of grant NCI 1RCA207689-01A1

Detailed description

Patients will be recruited via a secure, clinical data warehouse to complete a patient-randomized test of the efficacy of the intervention for promoting initial and repeat FIT testing. Patients identified as eligible will be contacted through MyChart to test a web-based, culturally-sensitive virtual human intervention for CRC screening. The web-application will provide information to encourage CRC screening. Therefore, this study is a minimal risk study.

Interventions

OTHERvirtual technology

The app will first ask participants a short series of questions designed to assess their baseline risk for colon cancer. Highly tailored patient reminders will be customized using all 12 constructs.

Scale: 5-point Likert scale (1 = strongly disagree to 5 = strongly agree). Mean scores near 1 indicate a lower intention to get screened for colorectal cancer. Mean scores near 5 indicate a higher intention to get screened for colorectal cancer. Construct: Behavioral intention to screen No subscales

Virtual Human (VH) Screening
Patients were randomly assigned to a virtual human (VH) screening condition after completing the eligibility for CRC requirements. virtual technology - highly tailored VH: The app will first ask participants a short series of questions designed to assess their baseline risk for colon cancer. Highly tailored patient reminders will be customized using all 12 constructs. The VH-tailored content was presented using an animated computer-generated character to deliver tailored, culturally aligned health messages about CRC screening.

Text-Based (TB) Screening
Patients were randomly assigned to a text-based (TB) screening condition after completing the eligibility for CRC requirements. virtual technology - tailored minimally TB: The app will first ask participants a short series of questions designed to assess their baseline risk for colon cancer. Minimally tailored patient reminders will be customized using 4 randomly selected constructs. The TB-tailored content was presented using an image of a computer-generated character to deliver tailored, culturally aligned health messages about CRC screening.
