What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| SSB Intention | Intention to consume SSBs measured by hypothetical selection of a beverage from images of beverage options. | Up to 20 minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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). | 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). | 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. | 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) . | Up to 20 minutes |
