About this study

The purpose of this study is to find out whether the way a breast cancer risk estimate is presented affects how women feel about their risk and whether they believe the estimate is accurate for them. Women aged 39-74 will complete an online survey in which they receive a personalized breast cancer risk estimate using the Breast Cancer Risk Assessment Tool (BCRAT). The study includes two experiments. In the first experiment, women are randomly assigned to receive their estimate in different formats: some will see their risk over 5 years, 10 years, or a lifetime, and some will see their risk expressed out of 100 women or out of 1,000 women. In the second experiment, women receive their estimate and then have the opportunity to read answers to frequently asked questions about how breast cancer risk is calculated and what the estimate means. In both experiments, women are asked whether they believe the estimate reflects their true risk. Both experiments are conducted online through a national survey panel.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Risk Presentation FormatBehavioural

    Participants receive a personalized breast cancer risk estimate generated by the Gail Model. The format of the estimate varies by random assignment across two dimensions: temporal framing (5-year, 10-year, or lifetime risk) and denominator (risk expressed out of 100 women or out of 1,000 women). All other elements of the risk presentation are held constant across conditions.

  • Frequently Asked Questions ExposureBehavioural

    Participants receive a personalized breast cancer risk estimate generated by the Gail Model and then view an interactive FAQ document. The FAQ document was developed from qualitative interviews with women who had previously rejected their risk estimates and addresses common questions about how breast cancer risk is calculated, what factors the model does and does not include, what different risk levels mean, and how to discuss results with a physician. FAQ items are displayed as expandable questions; participants click to reveal answers. All participants receive the same FAQ document.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Risk Skepticism

    Participants' perception of their Gail model risk estimate is trichotomized into three categories: Underestimator (believed risk is lower than estimate), Agreer (believed risk equals estimate), and Overestimator (believed risk is higher than estimate).

    Measured: Day 1

  2. Risk Perception

    This measure includes two Likert scale questions assessing the perceived likelihood of developing cancer and the level of worry about getting cancer.

    Measured: Day 1

Questions about this trial

What is this clinical trial studying?

A study testing Risk Presentation Format and Frequently Asked Questions Exposure in people with Breast Cancer, run by University of Colorado, Denver at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 28 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Emily A Vidal, MS (303-724-5426, emily.a.vidal@cuanschutz.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Risk Skepticism (time frame: Day 1). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Aug 2026.
