Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control message group
Participants will not receive the priming manipulation.
No interventions assigned to this group
Health benefits priming group
Participants will be cueing with health benefits by asking to do a word-search exercise beginning with: "In the following, please choose words/statements that can indicate that having a healthy and sustainable diet can have health benefits, such as..."
Priming intervention
The priming manipulation will be embedded in one discrete choice experiment to test the effect of three priming interventions: priming with health benefits, environment benefits, and co-benefits of having sustainable diets, respectively, on consumers' preference for sustainable foods, and the relative importance of proximal attributes (e.g. taste and price) and distant attributes (e.g., attributes related to environmental sustainability) in determining food choice preference, as well as testing whether the effects of these three priming interventions can be modified by consumers' social orientation values. The cueing manipulation will be achieved by asking participants to complete a word-search exercise.
Environmental benefits priming group
Participants will be cueing with environmental benefits by asking to do a word-search exercise beginning with: "In the following, please choose words/statements that can indicate that having a healthy and sustainable diet can have environmental benefits, such as..."

Environmental and health co-benefits priming group
Participants will be cueing with environmental and health co-benefits by asking to do a word-search exercise beginning with: "In the following, please choose words/statements that can indicate that having a healthy and sustainable diet can have both benefits for health and the environment, such as..."
