Colorectal Cancer
Conditions
Brief summary
NORC/AmeriSpeak will recruit participants who meet the study criteria and invite them to complete a 15-minute survey. Participants will be randomly assigned to one of five conditions, with approximately 400 people in each condition, and will respond to various questions after viewing the study messaging. Once 2,000 participants complete the survey, the data will be de-identified and provided to the study team for analysis.
Detailed description
NORC/AmeriSpeak will put all of the study content into their system. They will send out the opportunity to participate in the study, which should take about 15 minutes, to people in their panel who meet our participation criteria. Participants will be directed to the study information sheet that includes all elements of consent. Participants who agree to participate will start the survey experiment. The survey experiment will randomize participants into one of five conditions: (1) control (no exposure), (2) overall median ranked messages (from the prior study), (3) messages preferred by all participants, (4) messages preferred by Black American participants, and (5) messages preferred by White American participants. Approximately 400 people will complete each condition. After viewing the study stimuli (or no stimuli in the control condition), participants will respond to various outcomes and other variables of interest (see questionnaire draft included). After all 2,000 people have completed the study, the study team will receive a de-identified data file from NORC/AmeriSpeak with all study data and engage in analysis. This study is planned to close the study around that time as the study team completes data analysis and write-up the findings.
Interventions
BEHAVIORALMedian Ranked Cancer Screening Messaging
Strong message content that increases screening and sharing intentions. Messages in this intervention were median ranked in the prior study.
BEHAVIORALOverall Preferred Cancer Screening Messaging
Strong message content that increases screening and sharing intentions. Messages in this intervention were highly rated messages by all participants in the prior study.
BEHAVIORALBlack American Preferred Cancer Screening Messaging
Strong message content that increases screening and sharing intentions. Messages in this intervention were highly rated messages by Black participants but not White participants in the prior study.
BEHAVIORALWhite American Preferred Cancer Screening Messaging
Strong message content that increases screening and sharing intentions. Messages in this intervention were highly rated messages by White participants but not Black participants.
BEHAVIORALControl
There will be no message content of cancer screening and sharing intentions in this arm.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intentions to Adhere to Colorectal Cancer Screening (CRCS) Recommendations | 15 minutes | After reading cancer screening (CRCS) recommendations, this outcome will assess how likely they are to follow on the the screening recommendations. Response options: Very unlikely (1), unlikely, neither unlikely nor likely, likely, very likely (5) A higher score indicates a favorable outcome, and a lower score indicates a less favorable outcome. |
| Intentions to Adhere Test Preference Indication | 15 minutes | To determine which colorectal cancer screening (CRCS) participants are most likely to choose. Response options: stool-based tests (e.g., FOBT or FIT); endoscopic/scoping approach (e.g., colonoscopy or sigmoidoscopy); whatever my doctor recommends to me; something other than a stool-based or scoping approach; I would not follow the recommendations. This outcome will report the count of responses. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Likelihood of Sharing Information Via Social Media | 15 minutes | This outcome measure will determine how likely participants are to share the messages about colon cancer screening on social media. Response options: Very unlikely (1), unlikely, neither unlikely nor likely, likely, very likely (5) A higher score indicates a favorable outcome, and a lower score indicates a less favorable outcome. |
| Information Sharing Behavior | 15 minutes | This outcome will report the count of participants will seek more information after the study. The participants will be asked a question on if they would like more information (Yes/No) and survey vendor will track participants who click a link to an external resource like the American Cancer Society to learn more. |
