Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
