Primary outcomePrimary: Mean Susceptibility to Vaping Score — 1.91; 1.82 score on a scale
Summary
The purpose of this trial is to determine whether a vaping prevention text message program reduces susceptibility to vaping among adolescents and young adults. This study addresses this issue by exposing participants to a vaping prevention text message program over a 28-day period in a randomized controlled trial with a matched attention control condition. A follow-up assessment is also made 4 weeks after the text messaging ends.
