About this study
Official title: Effects of Message Framing on Policy Support for Front-of-package Nutrition Labeling Among Latino and Limited English Proficiency Populations.
This study aims to assess whether different message framing about front-of-package labeling policies elicits more policy support than the control (no framing) among Latino and limited English proficiency populations. The study also seeks to identify which message framing elicits the most policy support.
Read the detailed description
Participants will complete a between-subjects online randomized experiment. Participants will be randomized to 1 of 4 arms: 1) No framing (control), 2) Information framing, 3) Healthier choices framing, and 4) Industry framing. In each arm, participants will view 1 message developed for their randomly assigned arm and indicate their policy support.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Exposure to information framing messageBehavioural
The information framing message presents the objective of the front-of-package labeling policy as providing nutritional information.
Exposure to healthier choices framing messageBehavioural
The healthier choices framing message presents the objective of the front-of-package labeling policy as encouraging consumers to make healthier choices.
Exposure to industry framing messageBehavioural
The industry framing message presents the objective of the front-of-package labeling policy as encouraging the food industry to make healthier products.
| Study group | Role | What they receive |
|---|---|---|
| Control (No framing) | No intervention | Participants will view one message about the front-of-package labeling policy. The message will display the same introductory sentence as all experimental arms, but it will not include a framed message about the objective of the front-of-package labeling policy. |
| Information framing | Experimental | Participants will view one message that frames the objective of the front-of-package labeling policy as providing nutritional information. Receives: Behavioral: Exposure to information framing message |
| Healthier choices framing | Experimental | Participants will view one message that frames the objective of the front-of-package labeling policy as encouraging consumers to make healthier choices. Receives: Behavioral: Exposure to healthier choices framing message |
| Industry framing | Experimental | Participants will view one message that frames the objective of the front-of-package labeling policy as encouraging the food industry to make healthier products. Receives: Behavioral: Exposure to industry framing message |
What is being measured
The primary outcome is the main question the study is designed to answer.
Support for the front-of-package labeling policy, proportion
Policy support will be assessed with 1 item: "How much would you support or oppose this policy?" This item will be measured on a 4-point scale ranging from (1) "Strongly oppose this policy" to (4) "Strongly support this policy", where higher scores indicate higher support for the front-of-package labeling policy. The final outcome will be dichotomized so that 0=Oppose this policy and 1=Support this policy.
Measured: During exposure to intervention (i.e., message about policy), assessed during one-time online 10-minute survey.
