Brief Summary
The aim of this study is to compare different sugary drink labels to see which most influence knowledge, beliefs, purchase intentions and choices. Parents of children ages 6-11 will shop in a virtual convenience store after being randomized to 1 of 4 conditions: 1) calorie labels; 2) text warning labels; 3) graphic sugar warning labels; or 4) graphic health warning. This study will provide data comparing the influence of sugary drink text warning labels and two kinds of graphic warning labels.

- +8 more secondary outcomes
Study Arms (4)
Calorie label
ACTIVE COMPARATORThis arm will display a "Calories per Bottle" label on all beverages, not just sugary beverages. This label is identical to the American Beverage Association's current "Clear on Calories" labels (as of 2018).
Text warning label
EXPERIMENTALThis arm will display similar text proposed in a recent sugary drink warning label bill in California. Sample text: WARNING: Drinking beverages with added sugar(s) contributes to obesity, type 2 diabetes, and tooth decay. The calorie label will also appear on all beverages.
Sugar graphic warning label
EXPERIMENTALThis arm will graphically display the amount of sugar in each sugary beverage along with the same text used in the "text warning label" arm. The calorie label will also appear on all beverages.
Health graphic warning label
EXPERIMENTALThis arm will graphically display potential negative health effects of over consuming sugary drinks for each sugary beverage, along with the same text used in the "text warning label" arm. The calorie label will also appear on all beverages.
