This research included over 500 participants recruited through social media. Almost 80% vaped daily. They all completed at least one of two coaching calls. Three months after joining the study, 45% of the 18-24 year-olds in the study were no longer vaping.
The research team randomly assigned participants to one of four options, as follows.
- Phone-based quitline coaching alone
- Coaching plus mailed nicotine replacement therapy
- Coaching plus mHealth (a mobile intervention offering texts, links to videos and other online education and support)
- Coaching, nicotine replacement and mHealth support
All four approaches helped young adults quit vaping, with almost half of participants abstinent after 3 months. Higher than anticipated quit rates reduced the power to identify significant group differences. Mailed NRT and mHealth did not significantly improve quit rates, in the context of an active control of a 2-call coaching program. |
