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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Video based decision aid | Experimental | 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. |
|
| Written decision aid | Experimental | 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. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Video based decision aid | Behavioral | A <4 minute video that describes the screening decision, risks, and benefits of screening |
|
| Measure | Description | Time Frame |
|---|---|---|
| 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). | Baseline and Immediately post intervention, about 20 minutes |
| Measure | Description | Time Frame |
|---|---|---|
| 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. | Baseline and Immediately post intervention, about 20 minutes |
| Percent correct knowledge of breast cancer screening score |

| Written decision aid | Behavioral | An electronic document that describes the screening decision, risks and benefits of screening |
|
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. |
| 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. | Baseline and Immediately post intervention, about 20 minutes |
