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

ranking task for these same attributes; or they will make a choice after viewing a balance
sheet of attributes.
