Online Study of Colorectal Cancer and Prostate Cancer Screening Decision Making (CARR2)

21. april 2017 opdateret af: University of North Carolina, Chapel Hill

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.

Studieoversigt

Detaljeret beskrivelse

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Andet: Rating and Ranking Group
A group of individuals from the United States and Australia who complete a 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.
Andet: Discrete Choice Group
A group of individuals from the United States and Australia who complete a discrete choice experiment 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.
Andet: Balance Sheet Group
Individuals from the United States and Australia who will complete an implicit values clarification 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.
