Colonic Cancer
Conditions
Brief summary
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).
Interventions
BEHAVIORALPerceived Effectiveness Prompt
Participants will assess pairs of messages with the prompt, Which of the messages below is more likely to make you want to get screened for colorectal cancer? Participants will also be able to provide their own idea for a message rather than selecting a message from the pairs presented.
BEHAVIORALPerceived Shareability Prompt
Participants will assess pairs of messages with the prompt, Which of the messages below would you be more likely to share with your friends or family? Participants will also be able to provide their own idea for a message rather than selecting a message from the pairs presented.

| Undetermined First Message Prompt These participants were not included in the analysis, as it was not clear if they saw the effectiveness/shareability prompt first.
As their group assignment could not be determined, the data from these participants were not included in the analysis, as their associated data was deemed unreliable. | 0 |

Outcome results
Primary
Number of Participants in Determining Messages
This outcome measure will report the number of participants who participated in determining the Online Messages About Colon Cancer Screening. This study will help determine the content of Colon Cancer Screening messaging for future research.
Time frame: 15 minutes
Population: Participants in the Undetermined First Message Prompt group were excluded from outcome measure reporting because 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
