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.

Detailed description

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).

Conditions

• Colorectal Cancer

Interventions

Type	Name	Description
OTHER	virtual technology - high interactive	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.
OTHER	virtual technology - low interactive	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.
OTHER	non-colorectal cancer related module	Participants engage with web-based content not related to colorectal cancer or nutrition.
