About this study
This is an online survey assessing consumer support for different labeling policies related to sugar sweetened beverages. The investigators will present consumers with three labels that are being considered for sugar sweetened beverages: a calorie label, a text warning label that says "Warning drinking beverages with added sugar(s) can lead to health problems like obesity, diabetes and tooth decay" and a graphic warning label that includes graphic images to correspond with each of the health problems listed with the text warning. The investigators will ask participants their support for each label. The investigators will also see if support for the labels change after learning of the effectiveness of these labels. The investigators will share the results of a recent field study that suggested calorie and textual warning labels had no influence on the purchasing of sugar sweetened beverages while the graphic label decreased purchasing by 11 percent.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Effectiveness of Labels in Reducing Purchasing of Sugar Sweetened BeveragesOther
In one of our parallel assigned conditions participants will receive additional information (e.g., an intervention) of effectiveness information. These consumers will learn how effective these labels were in reducing the purchasing of sugar sweetened beverages in a recent study.
Control conditionOther
In one of our parallel assigned conditions participants will receive no additional information and be asked to rate their support for the label.
| Study group | Role | What they receive |
|---|---|---|
| Consumer Support | Experimental | Participants will be presented with three labels: a calorie label, a textual warning label and a textual warning label with corresponding graphic images and will be asked to rate their support for each label on a 1 (not at all) to 7 (a great deal) scale. Receives: Other: Control condition |
| Consumer Support with Effectiveness Info | Experimental | Participants will be presented with three labels: a calorie label, a textual warning label and a textual warning label with corresponding graphic images and will be asked to rate their support for each label on a 1 (not at all) to 7 (a great deal) scale. Participants will also receive effectiveness information- how each label influenced the purchasing of sugar sweetened beverages- from a recent field experiment.
