+Outcome measures

Primary outcomes

  • SSB Intention [Up to 20 minutes]: Intention to consume SSBs measured by hypothetical selection of a beverage from images of beverage options.

Secondary outcomes

  • SSB Intention (2) [Up to 20 minutes]: Measured by survey items assessing intention to consume SSBs on a scale from 1 (not at all likely) to 7 (extremely likely).
  • SSB attitudes [Up to 20 minutes]: Measured by survey items assessing perceived healthfulness of SSBs on a scale from 1 (extremely unhealthy) to 7 (extremely healthy).
  • SSB knowledge [Up to 20 minutes]: Measured by survey items assessing knowledge of number of calories (estimate provided by participant) and sugar (estimated by participant, in teaspoons) contained in SSBs.
  • SSB norms [Up to 20 minutes]: 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) .

Other outcomes

  • SSB self-efficacy [Up to 20 minutes]: Measured by survey item assessing how confident participant feels in reducing SSB consumption, on a scale from 1 (not at all) to 5 (completely).
  • Social interaction [Up to 20 minutes]: Measured by survey item assessing likelihood participant will encourage others to reduce SSB consumption, on a scale from 1 (not at all) to 5 (completely).
