A Patient-centered Intervention Using Technology to Reduce Colorectal Cancer Disparities in Primary Care

April 17, 2025 updated by: University of Florida
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.

How is the study designed?

Design Details

  • Primary Purpose: Screening
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Virtual Human (VH)
Patients were randomly assigned to a virtual human (VH) screening condition after completing the eligibility for CRC requirements.
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.
Other Names:
  • Virtual human application (ALEX)
Experimental: Text-Base (TB)
Patients were randomly assigned to a text-based (TB) screening condition after completing the eligibility for CRC requirements.
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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Intention to Screen for Colorectal Cancer (CRC)
Time Frame: within the first 12 months

Measure: Intention to Screen for Colorectal Cancer Item: I want to get screened for colorectal cancer. 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

within the first 12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Communication With a Provider About Colorectal Cancer (CRC)
Time Frame: Assessed after 24 months

Measure: Intention to talk to doctor about colorectal cancer screening. Construct: Behavioral intention to communicate Item: I will talk to my healthcare provider about colorectal cancer screening. Scale: 5-point Likert scale (1 = strongly disagree to 5 = strongly agree). Mean scores near 1 indicate a lower intention to talk to a healthcare professional about colorectal cancer screening. Mean scores near 5 indicate a high intention to talk to a healthcare professional about colorectal cancer screening.

No subscales

Assessed after 24 months
