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).

Participants will be White (n=1,000) and Black (n=1,000) Americans between the ages of 45 and 74. The goal of the study is to determine if there are differences in message preferences and evaluations between these two groups due to historical disparities in colorectal cancer screening uptake and outcomes.

Participants in the "Undetermined First Message Prompt" group were excluded from baseline characteristics reporting because baseline characteristics data were not available. Data for this group were not collected during the study, as evidenced by blank fields or entries containing erroneous or unusable information. These participants could not be included in the reported dataset.
