Evaluating Online Messages About Colon Cancer Screening

The goal of the study is to determine, using a choice-based approach, what messages (pulled from various online sites) people find more and less persuasive and shareable on the topic of colorectal cancer screening. As a secondary goal, the study is interested how various information behaviors, such as people's self-reported seeking of health information and encountering of health information, demographic variables, individual difference variables, and message exposure associate with their intentions to adhere to recommended colorectal cancer screening guidelines from the National Cancer Institute. The study is interested at differences specifically among Black and White Americans of recommended screening age (45-74).
