An interventional study of Video based decision aid and Written decision aid in Mammography Screening, Geriatrics and Decision Aid, sponsored by Yale University. Active, not recruiting at 1 site in United States. Open to female participants aged 75 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-06-23.
Sponsored by Yale University · Not applicable, Interventional, and Supportive care
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.
Yale University is the lead sponsor of 1,724 studies on the registry; 298 are open to participants now.
Of its 210 completed or terminated interventional studies of FDA-regulated products, 126 (60%) have results posted.

Exclusion Criteria:
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.
Behavioral: Video based 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.
Behavioral: Written decision aid
A \<4 minute video that describes the screening decision, risks, and benefits of screening
An electronic document that describes the screening decision, risks and benefits of screening
Mean Decisional Conflict Scale (DCS) score
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).
Time frame: Baseline and Immediately post intervention, about 20 minutes
Mean Screening Intention score
Measures an individual's readiness or likelihood to undergo preventative health screenings. Total score range 1-15, higher scores indicate stronger intention.
Time frame: Baseline and Immediately post intervention, about 20 minutes
Percent correct knowledge of breast cancer screening score
Knowledge of screening will be quantified as the proportion of correct answers out of a total possible 9 questions in the pre test and 12 questions in the post test.
Time frame: Baseline and Immediately post intervention, about 20 minutes
Understanding of overdiagnosis
Understanding of overdiagnosis will be quantified as proportion of correct responses out of 3 questions about overdiagnosis.
Time frame: Baseline and Immediately post intervention, about 20 minutes
