Communicating Objective Risk for Personalized Decision Making About Mammography

20 de julho de 2017 atualizado por: University of Pennsylvania
The purpose of this study is to test the effects of objective risk information about breast cancer and mammography outcomes using a randomized control trial. Women between the ages of 35 and 49 will receive information about their personal risk for breast cancer and be randomly assigned to receive data about a woman who should be screened, data about the potential outcomes of screening, or data about breast cancer deaths. Two presentation formats will be tested and compared.

Descrição detalhada

This study will compare alternative strategies for the presentation of individualized information about the risks and benefits of mammography screening. The purpose of this study is to understand how objective risk information influences outcomes including behavioral intentions, attitudes about mammography, and emotional responses.

After participants view objective risk information, a post-test survey will measure outcome variables including behavioral intentions, knowledge, and emotional responses.

After reading information based on their condition, study participants will be asked to complete a series of questions to measure their reactions based on their condition. Specifically, the investigators will be measuring the following dependent variables (primary outcomes): behavioral intentions to receive mammograms, attitudes about mammography, subjective norms about mammography and breast cancer screening, knowledge about mammography outcomes and screening recommendations, and emotional responses to the material including psychological reactance. These outcomes will be measured using self-reported questionnaire items.

In this project, the investigators will compare alternative communication strategies to determine which strategy or strategies result in the greatest level of understanding. The investigators also will examine if the various strategies differentially affect the primary outcomes listed above.

Outras medidas de resultado

Medida de resultado
Descrição da medida
Prazo
Injunctive and descriptive norms about mammography
Prazo: immediately following intervention (time 0)
Participants will be asked to report their perceived norms about mammography, what they think important others would expect them to do and what they think other women their age or older are doing.
immediately following intervention (time 0)
Decisional satisfaction
Prazo: immediately following intervention (time 0)
This variable assesses how satisfied participants feel about making a decision about mammography given the information they have been provided. Items include, "The information in the decision aid made me feel the choice to get a mammogram is being taken away from me by the groups that make screening recommendations."
immediately following intervention (time 0)
Risk perception
Prazo: immediately before and after intervention (time 0)
This variable includes perceived severity and perceived susceptibility of breast cancer. Items include, "What is the chance that an average 40-49 year old woman will develop breast cancer in the next 10 years? Please choose a number between 0 (no chance of breast cancer) and 100 (definitely will get breast cancer)."
immediately before and after intervention (time 0)
Clarity of the information being presented
Prazo: immediately following intervention (time 0)
These items assess how easy it is for participants to understand the numerical information that is provided in the decision aid.
immediately following intervention (time 0)
Credibility of the information
Prazo: immediately following intervention (time 0)
These items measure the perceived trustworthiness, credibility, and accuracy of the information provided in the decision aid. Items include, "How credible did you find the information presented in the decision aid?"
immediately following intervention (time 0)
Emotional reactions
