Study Summary
The primary objective of this study is to determine to what degree sugary drink warning labels increase consumers' knowledge about the potential health harms of sugary drinks and reduce sugary drink intake. The study is designed to answer three additional questions: 1) Do some warning labels work better than others? 2) What is the effect of warning labels over time? 3) If warning labels influence behavior, is it because they increase knowledge or simply provide a salient reminder that some drinks are less healthy? This study will test the effect of repeated exposure to warning labels on total calories purchased over time and assess whether knowledge or salience better explain label effects.
Primary Outcome
total calories purchased over four weeks in an online store.
