Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Purpose: To evaluate reactions to and opinions of a messaging campaign. Participants: Participants will be recruited through Prime Panels and will be US-based adults (18 years old and older) who consumed red meat in the past 30 days. Procedures (methods): After completing a screening question about meat consumption, participants will review a consent form. If they select to participate in the study, participants will be randomly assigned to view control messages, red meat-related environment messages, or red meat-related health messages. They will be asked a series of questions about these messages. Participants will also be asked about grocery shopping preferences and standard demographics questions.
