This is a randomized online experiment testing different methods for communicating about the benefits and harms of breast cancer screening. Participants will be randomly assigned to experimental conditions which vary whether screening outcomes are referred to as "benefits and harms" vs. "outcomes that can happen with screening", and vary the presence or absence of information about improvements in breast cancer survivability. In a control condition, participants receive basic information about what mammography is (which is also information received in all other conditions). Primary outcomes include skepticism toward the information presented, and screening intentions.
This is a randomized online experiment testing different methods for communicating about the benefits and harms of breast cancer screening. Participants will be randomly assigned to 1 of 5 experimental conditions, in a 2 x 2 + 1 factorial design, which vary (1) whether screening outcomes are referred to as "benefits and harms" vs. "outcomes that can happen with screening", and (2) the presence or absence of information about improvements in breast cancer treatment and survivability. In a 5th arm, a control condition, participants receive basic information about what mammography is (which is also information received in all other conditions). Primary outcomes include skepticism toward the information presented, and screening intentions.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control condition | Experimental | Participants receive basic information about what mammography screening is |
|
| Harm/benefit language, survivability information | Experimental | Outcomes of screening are referred to as "harms" and "benefits"; information about breast cancer survivability is included |
|
| Harm/benefit language, no survivability information | Experimental | Outcomes of screening are referred to as "harms" and "benefits"; information about breast cancer survivability is not included |
|
| Outcomes that can happen language, survivability information | Experimental | Outcomes of screening are referred to as "outcomes that can happen"; information about breast cancer survivability is included |
|
| Outcomes that can happen language, no survivability information | Experimental | Outcomes of screening are referred to as "outcomes that can happen"; information about breast cancer survivability is not included |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Harm/benefit language vs. outcomes that can happen | Other | Information about mortality benefit, false positives and overdiagnosis are referred to throughout the communication as either "harms" and "benefits" or "outcomes that can happen". |
| Measure | Description | Time Frame |
|---|---|---|
| Skepticism toward the screening message | Skepticism toward the screening message is assessed using the RED scale, consisting of 11 questions each measured on a 7-point Likert scale | Participant experience entails a one-time survey. This outcome is measured in that survey, immediately after participants read information about mammography screening. |
