Official title
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
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
