NCT04562636

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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).
