Brief Summary
The primary objective of this study is to examine differences in intentions (measured by hypothetical beverage selection) between the following conditions: (1) Control condition: Viewing beverages with a barcode, (2) viewing beverages that have an icon-plus-text warning label, "WARNING: High in added sugar", (3) viewing a campaign message about warning labels in one's preferred language + viewing beverages with a barcode, and (4) viewing a campaign message about warning labels in one's preferred language + viewing beverages with the warning label above. An additional objective is to compare other message reactions and perceptions and perceptions of SSBs (sugar-sweetened beverages) between the conditions. This study will use an online randomized controlled trial among Latino/a/x adults to assign participants to one of the above conditions.

Outcome Measures
Primary Outcomes (1)
Intention to purchase a sugar-sweetened beverage in a hypothetical selection task (not a scale)
Measured in a hypothetical beverage selection task in which participants are shown supermarket shelves containing a variety of sugar-sweetened and non-sugar-sweetened beverages, labeled according to condition. Participants will be asked to select the one beverage they would want to purchase for themselves, and this outcome will be dichotomized as hypothetical selection of an SSB or not. Adapted from doi: 10.2105/AJPH.2021.306488.
Approximately 0.5-2 minutes
Secondary Outcomes (9)
Intention to consume sugar-sweetened beverages and water in the next 4 weeks (there is no scale title)
≤20 minutes
Scale title: University of North Carolina (UNC) Perceived message effectiveness (PME)
≤20 minutes
Noticing the label (not a scale)
≤20 minutes
Outcome expectations re: sugar-sweetened beverages increasing risk of type 2 diabetes, heart disease, and tooth decay (there is no scale title)
≤20 minutes
Perception of learning something new from the label (not a scale)

- +4 more secondary outcomes
Other Outcomes (1)
Intention to purchase a sugar-sweetened beverage for one's child under the age of 18 in a hypothetical selection task (not a scale)
Approximately 0.5-2 minutes
Study Arms (4)
Control bar code
PLACEBO COMPARATORViewing beverages that contain control labels (i.e., bar codes) on sugar-sweetened beverages
Warning label
EXPERIMENTALViewing beverages that contain an added-sugar warning label (icon-plus-text yellow label that says, "WARNING: High in added sugar," on sugar-sweetened beverages
Control bar code + informational campaign about warning labels
EXPERIMENTALViewing an informational campaign about warning labels followed by viewing beverages that contain control labels (i.e., bar codes) on sugar-sweetened beverages
Warning label + informational campaign about warning labels

Interventions
Viewing beverages that contain control labels (i.e., bar codes) on sugar-sweetened beverages
Viewing beverages that contain an added-sugar warning label (icon-plus-text yellow label that says, "WARNING: High in added sugar," on sugar-sweetened beverages
Viewing an informational campaign about added-sugar warning labels. The poster will be shown in Spanish (instead of English) if the participant reports speaking and reading in Spanish better than English.
