This randomized trial aims to test the effects of co-created breast cancer counter marketing intervention messages for reducing alcohol consumption and impacting awareness and beliefs about the breast cancer risks from alcohol consumption in young adult women.

Not pregnant or intending to become pregnant by self-report.
Assigned male at birth
Ages <18 or >25 at enrollment

Alcohol and Breast Cancer Risk Messages
BehavioralParticipants will be randomized in a 1:1 ratio to the intervention or control arm. In the intervention arm, participants will receive the co-created intervention content. The investigators co-created the intervention content, including visuals and text, through focus groups with young adult women and refined the draft content based on additional feedback from focus groups, thereby ascertaining the views of young adult women. The intervention content aligns with a conceptual framework and includes messaging with the following themes: 1) Risks of breast cancer from alcohol consumption; 2) Efficacy content promoting behavior change; 3) Relevance to young adult women; 4) Mechanisms through which alcohol consumption increases breast cancer risk; 5) Exposing the alcohol industry's deceptive marketing practices; 6) Comparisons to other behavioral risk factors for cancer.
Skin Cancer Risk Messages
BehavioralParticipants in the control arm will receive text only content about skin cancer risk and prevention. This is based on intervention trials in other cancer prevention areas (e.g., tobacco) where the investigators used this type of control, provides a contact-matched comparison relative to the intervention arm, and ensures consistency of the protocol (e.g., timing of completion and content of measures to be completed) across the trial arms.
Alcohol Consumption
Alcohol consumption will be measured using the Timeline Follow Back, a valid self-report measure of daily alcohol consumption over the past 4 weeks. The Timeline Follow Back captures alcohol consumed each day in the past 4 weeks. The measure is administered at the end of the intervention, 4 weeks post intervention, and 12 weeks post intervention. Lower alcohol consumption is considered a better outcome.
Daily Alcohol Consumption
Daily alcohol consumption will be measured using Ecological Momentary Assessments, brief daily questions sent to participants' mobile phones that participants answer about whether they drank alcohol and, if so, how much. Daily assessment periods capture alcohol consumption from the end of the intervention to 4 weeks post-intervention, and from 8 weeks to 12 weeks post intervention. Lower daily alcohol consumption is considered a better outcome.
Intentions to Reduce Alcohol Consumption
Intentions to reduce alcohol consumption will be measured with two valid self-report items on a 1-4 scale. The items are averaged to create an overall score. Higher intentions to reduce alcohol consumption is considered a better outcome. The measure is administered at the end of the intervention, 4 weeks post intervention, and 12 weeks post intervention.
Alcohol and Breast Cancer Risk Beliefs
Alcohol and breast cancer risk beliefs will be measured using 2 valid self-report items on a 1 to 7 scale. Items will assess perceived risk of breast cancer from drinking alcohol and worry about the harm of breast cancer from drinking alcohol. The items are averaged to create an overall score. Higher risk beliefs are considered a better outcome. The measure is administered at the end of the intervention, 4 weeks post intervention, and 12 weeks post intervention.
