NCT04192071

Brief Summary

This study uses the opinions of adults between the ages of 45 and 73 years old to develop and test an interactive nutrition module for use in an existing colorectal cancer screening intervention using virtual human technology. The main questions answered include:

  • What content do adults want to receive from a web-based interaction about colorectal cancer screening and nutritional risks for colorectal cancer?
  • Does a brief interaction with a virtual human delivering tailored cancer prevention information impact cancer prevention intentions and attitudes among a national sample of geographically rural U.S. adults? This study will contribute to knowledge of what messages and graphics promote understanding of cancer risk and promote screening with the potential to promote behaviors that reduce cancer risk.

Outcome Measures

Primary Outcomes (3)

  • Risk Perceptions for Colorectal Cancer

    Items measured on a 7-point Likert scale, (e.g. "My chances of getting colorectal cancer are high"), where 1 is strongly disagree and 7 is strongly agree.

    up to 2 hours

  • Intentions to Screen for Colorectal Cancer

    Two individual items assessed intentions to screen: 1. A single item measured intentions to screen for colorectal cancer (readiness to screen) adapted from (Boonyasiriwat, Hung, Hon, et. al, 2014.) Participants answer the following prompt: "Please indicate what best represents your plans for colorectal cancer screening". Response options str: 1 point = I am not planning to screen in the next 6 months; 2 points = I am thinking about screen, but not in the next 6 months; 3 points = I am considering screening in the next 6 months and 4 points for = I am already taking steps to screen in the next 6 months. Higher scores =higher readiness to screen (better outcome). Min. score = 1 ; Max. score =4. 2. a single item assessed intentions on a Likert Scale. Question: "I want to get screened for colorectal cancer" where: 1 = strongly disagree-7 = strongly agree). Min. score = 1 - Max. score is 7. Higher scores indicate a stronger desire to obtain screening (better outcome).

    up to 2 hours

  • Information Seeking Behavior

    Does participant click on link to more information. The survey platforms event tracking feature will be used to track clicks (yes/no) for more information.

    up to 2 hours

Study Arms (3)

high interactive virtual human administered nutrition module

ACTIVE COMPARATOR

The virtual health assistant will interactively collect nutrition information (alcohol, red meat, and processed meat intake) and report risk information back to users in visual and audio format

Other: virtual technology - high interactive

low interactive virtual human module

ACTIVE COMPARATOR

Complete the current intervention module that includes items assessing alcohol and meat intake.

Other: virtual technology - low interactive

attention control module

SHAM COMPARATOR

The attention control group, will complete a related module not related to colorectal cancer or nutrition

Other: non-colorectal cancer related module

Interventions

Participants engage with web-based cancer prevention content and answer a short series of questions designed to assess their baseline risk for colon cancer and dietary intake. Interactive nutrition risk feedback will be customized based on user input.

Also known as: Virtual human nutrition module
high interactive virtual human administered nutrition module

Participants engage with web-based cancer prevention content and answer a short series of questions designed to assess their baseline risk for colon cancer. Minimally interactive risk feedback will be delivered.

Also known as: virtual human standard
low interactive virtual human module

Participants engage with web-based content not related to colorectal cancer or nutrition.
