Brief summary
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.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean Decisional Conflict Scale (DCS) score | 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). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mean Screening Intention score | Baseline and Immediately post intervention, about 20 minutes | Measures an individual's readiness or likelihood to undergo preventative health screenings. Total score range 1-15, higher scores indicate stronger intention. |
| Percent correct knowledge of breast cancer screening score | Baseline and Immediately post intervention, about 20 minutes | 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. |
| Understanding of overdiagnosis | Baseline and Immediately post intervention, about 20 minutes | Understanding of overdiagnosis will be quantified as proportion of correct responses out of 3 questions about overdiagnosis. |
