简要总结
Purpose: To assess the impact of taxes, warnings, and a combination of taxes and warnings on US adults' decisions to purchase products that contain red meat in an online grocery store.
Procedures (methods): Participants will be recruited from Prime Panels (an online panel research company). Following online consent, participants will be assigned to one of four trial arms: 1) Control (no warning and no tax), 2) Warnings (all products that contain red meat have a health warning and environmental warning), 3) Tax (30% tax on products that contain red meat), and 4) Combined warning and tax (all products that contain red meat will have the two warnings and a 30% tax). Then, participant will enter an online grocery store reflecting their assigned arm. The participant will be instructed to complete a shopping task in the online grocery store. After completing the shopping task, participants will be redirected to an online survey and answer a series of questions about the shopping task, labels (excluding tax and control groups), and taxes (excluding warning and control groups). Questions will also include standard demographic and health related variables.
详细描述
Participants will be recruited from Prime Panels (an online panel research company). Following online consent, participants will be randomly assigned to one of four trial arms affecting the appearance of an online grocery store. Once in the online grocery store, participants will complete a shopping task. The participants will have 9 specified items to add to their shopping cart (1 pizza, 1 burrito, Burger patties [meat or vegetarian], Breakfast sausages [meat or vegetarian], 1 frozen individual meal, 1 loaf of bread, 1 sandwich filling [for example, ham, turkey, or peanut butter], 1 pack of tortillas, 1 taco filling [for example, steak, chicken, or beans]). Participants will be informed that they will not be spending any of their own money to complete the shopping task. After completing the shopping task, participants will be redirected to a survey. They will provide self-reported responses to survey questions (e.g. perceived healthfulness from eating red meat, perceived risk of cancer from eating red meat, thinking about the health/environmental harms of food products). Participants will also answer demographic and health related questions.
