Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this online RCT study is to examine how sugar-sweetened beverage (SSB) health warnings influence US adults' perceptions and reactions. The investigators have the following predictions: 1. SSB warnings will be perceived as more effective than the control (message topic) 2. Icon and graphic warnings will be perceived as more effective than text-only warnings (message type) The investigators will also examine the interaction of warning topic and warning type, but have no specific hypothesis about this interaction. Finally, the investigators will test the following predictions about the secondary outcomes: SSB warnings (vs. control), as well as icon and graphic warnings (vs text.warnings), will lead to lower perceived product healthfulness, lower purchase intentions, and higher cognitive elaboration.
