Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study occurred in two phases. Phase one was a qualitative aim that collected feedback from participants in iterative cycles of focus groups and individual think-aloud interviews. Phase one feedback was analyzed and applied to develop a tailored, web-based prototype that addressed participant desires for an intervention to address colorectal cancer prevention and nutrition risk education. The prototype was a brief conversation delivered by an interactive Virtual Health Assistant (virtual character with audio and visual elements that mimic a conversation with a human).

high interactive virtual human administered nutrition module

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

Group Type ACTIVE_COMPARATOR

virtual technology - high interactive

Intervention Type OTHER

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.

low interactive virtual human module

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

Group Type ACTIVE_COMPARATOR

virtual technology - low interactive

Intervention Type OTHER

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.

attention control module

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

Group Type SHAM_COMPARATOR

non-colorectal cancer related module

Intervention Type OTHER

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