Measure	Perceived Shareablility Prompt First Perceived 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. Perceived 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.	Perceived Effectiveness Prompt First Perceived 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. Perceived 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.

PRIMARY outcome

Timeframe: 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

SECONDARY outcome

Timeframe: 15 minutes

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.
