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.
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 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. |
|
| 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. |
|
| 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. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Exposure to information framing message | Behavioral | The information framing message presents the objective of the front-of-package labeling policy as providing nutritional information. |
| Measure | Description | Time Frame |
|---|---|---|
| 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. | During exposure to intervention (i.e., message about policy), assessed during one-time online 10-minute survey. |
