About this study
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).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Perceived Effectiveness PromptBehavioural
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.
Perceived Shareability PromptBehavioural
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.
| Study group | Role | What they receive |
|---|---|---|
| Perceived Shareablility Prompt First | Not described Receives: Behavioral: Perceived Effectiveness Prompt; Behavioral: Perceived Shareability Prompt | |
| Perceived Effectiveness Prompt First | Not described Receives: Behavioral: Perceived Effectiveness Prompt; Behavioral: Perceived Shareability Prompt |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 15 minutes
Secondary outcomes (1)
Intentions to Follow Screening Recommendations in the Future
Single item self-report of intentions to follow USPSTF recommendations for colorectal cancer screening on a seven-point scale. A low score (Minimum: 1 Extremely Unlikely to follow USPSTF recommendations) is an unfavorable outcome and a high score (Maximum: 7 Extremely Likely to follow USPSTF recommendations) is a favorable outcome.
Measured: 15 minutes
