Overdiagnosis and Breast Cancer Screening Decisions

Purpose

This is a survey-based study using an online panel. The goal of the study is to understand whether information about overdiagnosis influences breast cancer screening intention among older women. Participants are first asked a series of questions about breast cancer screening including their intention to continue screening, knowledge of screening, and beliefs about screening. They are then shown one of three videos about breast cancer screening that contain information about overdiagnosis or a fourth control video that is identical but contains no information about overdiagnosis. Participants are then again asked about screening intention, along with knowledge of screening, overdiagnosis, and questions around trust.

Arm Groups

Arm	Description	Assigned Intervention
Experimental Low risk of overdiagnosis	Participants in this arm will be shown a decision aid in which risk of overdiagnosis is low.	Behavioral: Breast cancer screening decision aid -- low risk Participants in this study will view a video-based decision aid that describes the risks and benefits of breast cancer screening for older women. Participants assigned to the low risk of overdiagnosis arm will view a version of the decision aid the describes a low risk of overdiagnosis.
Experimental Moderate risk of overdiagnosis	Participants in this arm will be shown a decision aid in which risk of overdiagnosis is moderate.	Behavioral: Breast cancer decision aid -- moderate risk Participants in this study will view a video-based decision aid that describes the risks and benefits of breast cancer screening for older women. Participants assigned to the moderate risk of overdiagnosis arm will view a version of the decision aid the describes a moderate risk of overdiagnosis.
Experimental High risk of overdiagnosis	Participants in this arm will be shown a decision aid in which risk of overdiagnosis is high.	Behavioral: Breast cancer screening decision aid -- high risk Participants in this study will view a video-based decision aid that describes the risks and benefits of breast cancer screening for older women. Participants assigned to the high risk of overdiagnosis arm will view a version of the decision aid the describes a high risk of overdiagnosis.
Active Comparator Control	Participants in this arm will be shown a video about breast cancer screening that is identical in all ways but contains no information about overdiagnosis.	Other: Control condition Participants in this study will view a video-based decision aid that describes the risks and benefits of breast cancer screening for older women. Participants assigned to the control arm will view a version of the decision aid that does not contain any information about overdiagnosis.
