Overdiagnosis and Breast Cancer Screening Decisions
Sponsor: Yale University
Summary
This is a survey-based study using an online panel. The goal of the study is to understand whether information about overdiagnosis influences breast cancer screening intention among older women. Participants are first asked a series of questions about breast cancer screening including their intention to continue screening, knowledge of screening, and beliefs about screening. They are then shown one of three videos about breast cancer screening that contain information about overdiagnosis or a fourth control video that is identical but contains no information about overdiagnosis. Participants are then again asked about screening intention, along with knowledge of screening, overdiagnosis, and questions around trust.
