Summary
The aim of this study is to test intervention components to help young adults quit vaping. A
2x2 factorial design will be used where all participants receive quitline-delivered
behavioral phone counseling, and components to be tested are a digital intervention (with
text and online cessation support) and nicotine replacement therapy (NRT).
The research questions and hypotheses for this study are:
1. Which components and combinations of intervention yield the greatest success rates for
exclusive vaping cessation among young adult exclusive e-cigarette users? H1: The
complete condition (NRT + digital) will yield significantly higher rates of cessation
compared to the control condition (quitline only).
2. Does 8 weeks of nicotine replacement therapy (NRT) improve initial cessation outcomes
relative to no NRT.
H2: Providing NRT will yield significantly higher quit rates compared to the No NRT
condition.
3. Do tailored text-messages and online support during cessation improve initial cessation
outcomes relative to no digital content? Are young adult vapers engaged with and
satisfied with digital cessation tools? H3: Digital support will yield significantly
higher quit rates compared to no digital support.
H4: Higher engagement in digital content will be associated with higher cessation success
rates.
