What is being measured
The primary outcome is the main question the study is designed to answer.
SSB Intention
Intention to consume SSBs measured by hypothetical selection of a beverage from images of beverage options.
Measured: Up to 20 minutes
Secondary outcomes (4)
SSB Intention (2)
Measured by survey items assessing intention to consume SSBs on a scale from 1 (not at all likely) to 7 (extremely likely).
Measured: Up to 20 minutes
SSB attitudes
Measured by survey items assessing perceived healthfulness of SSBs on a scale from 1 (extremely unhealthy) to 7 (extremely healthy).
Measured: Up to 20 minutes
SSB knowledge
Measured by survey items assessing knowledge of number of calories (estimate provided by participant) and sugar (estimated by participant, in teaspoons) contained in SSBs.
Measured: Up to 20 minutes
SSB norms
Measured by survey item assessing how often participants perceive their peers to consume SSBs (1 = multiple times a day, 2 = daily, 3 = weekly, 4 = less than once a week, and 5 = never) and item on perception that people who are important to the participant would want them to limit SSB intake, on a scale from 1 (not at all) to 5 (completely) .
Measured: Up to 20 minutes
