简要总结
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.

研究组 & 干预措施
Video based decision aid
Participants in this arm will be shown a video based decision aid about breast cancer screening that includes information about the potential benefits and potential risks. The video includes both information explaining these risks and benefits, along with quantitation of risks and benefits. Participants will answer questions before and after watching the video.
干预措施: Video based decision aid (Behavioral)
Written decision aid
Participants in this arm will be shown a written decision aid about breast cancer screening that includes information about the potential benefits and potential risks. The written decision aid includes both information explaining these risks and benefits, along with quantitation of risks and benefits. Participants will answer questions before and after viewing the written document.
干预措施: Written decision aid (Behavioral)
结局指标
主要结局
Mean Decisional Conflict Scale (DCS) score
时间窗: Baseline and Immediately post intervention, about 20 minutes
DCS is a 16-item scale measuring uncertainty in health choices, covering informedness, values, support, uncertainty, and effective decision-making. Total scores range from 0 (no conflict) to 100 (high conflict).
次要结局
- Mean Screening Intention score(Baseline and Immediately post intervention, about 20 minutes)
- Percent correct knowledge of breast cancer screening score(Baseline and Immediately post intervention, about 20 minutes)
- Understanding of overdiagnosis(Baseline and Immediately post intervention, about 20 minutes)
