Actual (reported)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.

Actual (reported)Perceived Message Effectiveness (PME)
Perceived effectiveness of the messages will be measured during the message using 4 items adapted from Baig et al. (2018): concern, unpleasantness, and discouragement. The averaged responses on the 4 items will be used to create a PME score. All 4 items are measured using a a 1 to 5 likert scale, with higher scores representing a higher amount of the construct. Questions: How much do these messages... * make you concerned about the health effects of eating red meat? * make you concerned about the environmental effects of eating red meat? * discourage you from wanting to eat red meat? * make eating red meat seem unpleasant to you? 1. Not at all, 2=Very little, 3=Somewhat, 4=Quite a bit, 5=A great deal).
