This is a randomized survey study of 2 decision aids for breast cancer screening. Decision aids are tools that present structured information to patients about a medical test or treatment. The goal of this study is to compare a video-based decision aid to a written decision aid and assess the impact on intention to screen in the future, readiness to make a decision about screening, and knowledge of screening. The study will use an online survey platform (YouGov) and will include women 75 and older who have been previously screened for breast cancer and do not have a history of breast cancer.
