Perceived Effectiveness of Vaping Prevention Ads Among Adolescents and Young Adults

The purpose of the Aim 2 study is to assess the perceived effectiveness of vaping prevention ads among adolescents and young adults and identify which features of video ads predict perceived message effectiveness. Participants will include adolescents aged 13-17 and young adults aged 18-20 who live in the US and who are susceptible to vaping or who currently vape. In an online survey, participants will be randomized to view five randomly selected vaping prevention ads identified from a previous content analysis. After viewing the videos, participants will rate each video on the perceived message effectiveness scale and respond to questions about vaping appeal and urge to vape. The survey will take 15-20 minutes. A follow-up survey of a subset of participants will be conducted around two weeks after they have been exposed to vaping prevention video ads in the baseline survey. Participants will view a total of six videos, including the five videos they watched previously, shown one at a time, along with one "decoy" video ad. After watching each video ad, participants will indicate whether they remember seeing the ad in the survey they took around two weeks prior. The survey will take 10-15 minutes.

Inclusion Criteria: * Age 13-20 years old * Current vaper (defined as using e-cigarettes in the past 30 days) or susceptible to vaping. Participants will be considered 'susceptible to vaping' if they answer anything other than "definitely not" to 3 screening items assessing their susceptibility to vaping. An example item is, "If one of your best friends were to offer you a vape, would you use it?" (Definitely not, probably not, probably yes, definitely yes). * Live in the United States Exclusion Criteria: • Live outside of the United States
