Participant-reported most important attribute from survey [ Time Frame: 1 day ] [ Designated as safety issue: No ]
The single most important colon cancer or prostate cancer screening attribute indicated by the participant surveys. Each participant will be randomly assigned to take one of three survey versions: either (1) a conjoint analysis task wherein they will be asked to make a series of choices between hypothetical screening testing strategies with different attributes; (2) a rating and ranking task for these same attributes; or (3) they will make a choice after viewing a balance sheet of attributes.

Online Study of Colorectal Cancer and Prostate Cancer Screening Decision Making
A Comparison of the Effect of a Conjoint Analysis Based Values Clarification Exercise, Rating and Ranking Exercise, and Balance Sheet for Colorectal Cancer Screening and Prostate Cancer Screening Decision Making

Participants will be recruited from the United States and Australia to take an online survey about colon cancer screening or prostate cancer screening. Individuals selected for both the prostate cancer survey and the colon cancer study will be randomized to take one of three survey types - balance sheet, rating and ranking or conjoint analysis. These surveys will help participants clarify their values and opinions about screening options for colon cancer or prostate cancer. Participants' responses to the online survey are measured at one point in time - the time at which the participant takes the survey.

This study will compare effect of a conjoint analysis based values clarification exercise, ranking and rating, and a balance sheet on screening test preferences for colorectal cancer screening and prostate cancer screening using online surveys. Recruitment will be conducted through Survey Sampling International (SSI), an online survey research firm. Participants will be randomized to one of three arms to take online surveys. Patients will complete either a conjoint analysis task, in which they will be asked to make a series of choices between hypothetical screening testing strategies with different attributes; a rating and ranking task for these same attributes; or they will make a choice after viewing a balance sheet of attributes.

  • Colorectal Cancer
  • Colon Cancer
  • Prostate Cancer
  • Other: Rating and Ranking Task
    Individuals who are randomized to the rating and raking arm will be asked to complete an informational task in a rating and ranking format. The task will help individuals clarify their opinions and preferences regarding colon cancer and prostate cancer screening.
  • Other: Discrete Choice Task
    Individuals who are randomized to the rating and raking arm will be asked to complete an informational task in a discrete choice format. The task will help individuals clarify their opinions and preferences regarding colon cancer and prostate cancer screening.
  • Other: Balance Sheet Task
    Individuals who are randomized to the rating and raking arm will be asked to complete an informational task in a balance sheet format. The task will help individuals clarify their opinions and preferences regarding colon cancer and prostate cancer screening.
  • Rating and Ranking Group
    A group of individuals from the United States and Australia who complete a rating and ranking task.
    Intervention: Other: Rating and Ranking Task
  • Discrete Choice Group
    A group of individuals from the United States and Australia who complete a discrete choice experiment task.
    Intervention: Other: Discrete Choice Task
  • Balance Sheet Group
    Individuals from the United States and Australia who will complete an implicit values clarification task
    Intervention: Other: Balance Sheet Task
