Summary
The purpose of this randomized controlled trial is to determine whether exposure to vaping prevention advertisements (ads) reduce susceptibility to vaping among adolescents. Previous studies have been informative, but they have tended to be one-time experimental studies that do not replicate the repeated exposures to ads that people have in the real world. This study addresses this issue by repeatedly exposing participants to vaping prevention ads over time. Participants will be adolescents aged 13-17 who currently vape or who are susceptible to vaping.
Participants will be randomly assigned to ad stimuli. They will be assigned to one of two The Real Cost trial arms-health harms or addiction-or to a control trial arm (probability of assignment is 1/3 for all trial arms). Participants in the study will take 4 online surveys over a 3-week period, once per week (At week 0, 1, 2, and 3). All participants will view randomized ad stimuli based on their trial arm and answer surveys items at each session.
