Actual (reported)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.

Likely to serve or buy these beverages:
The survey will take up to 20 minutes
Parent feels good serving the beverages
The survey will take up to 20 minutes
Child enjoyment of beverages

This 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).
This 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.
This information appears in the description of the study arms.
