Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

• Perceived Message Effectiveness

  The 3-item perceived message effectiveness scale assesses the extent to which participants perceived the vaping prevention video ads as effective. Response options are on a 5-point scale from 1="Not at all" to 5="A great deal". The overall scale score is determined by averaging scores from the 3 items, with higher scores representing higher perceived message effectiveness. This is the primary outcome for the main study.

  Baseline (Main study)

• Recognition

  This survey item assesses whether the participant remembers viewing the ad in the baseline survey 2 weeks prior. Response options are "Yes", "No", and "Not sure". The response will be dichotomized as 1 = "Yes" and 0 = "No"/"Not sure" for analyses. This is the primary outcome for the follow-up study.
