Conditions Colonic Neoplasms
Colorectal Neoplasms
Colonic Diseases

Enrollment 486
Recruitment Details We sent electronic invitations to prospective participants from two opt-in registries: 1) Washington University’s Volunteer for Health Research Participant Registry and 2) ResearchMatch.org hosted by Vanderbilt University.
Pre-assignment Details Nearly all participants completed all study components online. They provided informed consent and proceeded to the baseline survey (n=486). Only those that completed the baseline survey were randomized (n=477) to one of three intervention conditions, so that number is smaller than the total who started the study.

1.Primary Outcome
Title Intentions to Get Screened for Colon Cancer
Hide Description Intention was measured on all surveys with the mean of 3 items assessed using slider bars (coded 1=not at all – 100=extremely) asking about the likelihood of being screened in the next 6 months, the importance of screening, and commitment to screening. Higher scores indicate greater intentions to get screened for colorectal cancer.

2.Secondary Outcome
Title Identification With the Character
Hide Description Participants assigned to narrative conditions were asked if they liked and felt similar to the character in the story they read with 3 items each with response options 1=Strongly Disagree – 5=Strongly Agree. Measures were based on previous work by the study investigators. Mean scores for liking and similarity were created; higher scores reflect higher perceived similarity and liking for the character. Means will be compared between the two groups assigned to read a narrative.

3.Secondary Outcome
Title Three Measures of Engagement
Hide Description Confirmatory factor analyses did not support an aggregate measure adapted from an existing transportation scale, so a single item “What I just read affected me emotionally” was used to measure emotional engagement for all participants. For participants assigned to either narrative condition, two items reflected cognitive (imagery) engagement “While I was reading the story, I could easily picture the events in it taking place” and “I had a vivid mental image of the person in the story”. Mean scores were created for cognitive engagement. Two items reflected self-referencing engagement: “I could picture myself in the scene of the events described in the story” and “The events in the story are relevant to my life” were assessed and mean scores created for self-referencing engagement. Responses for all items were 1=Not at all – 7=Very much. Higher mean scores reflected higher engagement.

Title Absolute Perceived Susceptibility to Colon Cancer
Hide Description Absolute perceived risk was assessed with three items: I am at risk for developing colorectal cancer, If I do not get screened regularly, I would feel vulnerable to developing colorectal cancer, If I do not get screened regularly, it is likely that I will develop colorectal cancer. Response options range from 1=strongly disagree to 5=strongly agree. Mean scale scores were created and higher scores reflect greater perceived susceptibility to colorectal cancer. Mean scores will be compared between all three study groups.

Title Perceived Benefits and Barriers of Colorectal Cancer Screening
Hide Description Perceived colorectal cancer screening benefits (8 items) barriers (6 items) are assessed with items from previously validated scales. Response options range from 1=strongly disagree to 7=strongly agree. Mean scores were created for each scale; higher scores reflect greater perceived benefits and barriers of getting screened. Means will be compared between all three study groups.
