Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Participant-reported most important attribute from survey
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.

Study Arms (3)
Rating and Ranking Group
OTHERA group of individuals from the United States and Australia who complete a rating and ranking task.
Discrete Choice Group
OTHERA group of individuals from the United States and Australia who complete a discrete choice experiment task.
Balance Sheet Group
OTHERIndividuals from the United States and Australia who will complete an implicit values clarification task
Interventions
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.
