Brief Summary

This research study, conducted by Truth Initiative, will help us learn how text messaging can help adolescents between 13 and 17 years of age quit vaping.

Detailed Description

The Teen Quit Vaping Study (QVS Teen) is a comparative effectiveness trial to evaluate the effectiveness of a quit vaping text message program in promoting abstinence from e-cigarettes among young users aged 13-17. This study is a 3-arm randomized controlled trial conducted among young users aged 13-17 recruited through online channels. Participants will be randomized to a quit vaping text message intervention, an assessment-only control condition, or a waitlist control condition. The primary aim is to examine 30-day point prevalence abstinence at 7-months post enrollment (roughly corresponds to 6-months post-treatment).

Arm && Interventions

Group	Intervention	Description
Assessment only control	Assessment only control	After an initial enrollment message, participants will be contacted monthly to assess e-cigarette use. At the end of the study data collection period, they will receive information on how to sign up for This is Quitting if they are interested in the program.
This is Quitting	This is Quitting	Participants will be enrolled to receive messages from This is Quitting. Users receive one age-appropriate message per day tailored to their enrollment date or quit date, which can be set and reset via text message. Those not ready to quit receive 4 weeks of messages focused on building skills and confidence. Users who set a quit date receive messages for a week preceding it and 8 weeks afterward that include encouragement and support, skill- and self-efficacy building exercises, coping strategies, and information about the risks of vaping, benefits of quitting, and cutting down to quit. Keywords COPE, STRESS, SLIP, and MORE provide on-demand support.
Waitlist control	Waitlist control	After an initial enrollment message, participants will receive no contact from study staff except for 1-month and 7-month follow-up assessments. At the end of the study data collection period, they will receive information on how to sign up for This is Quitting if they are interested in the program.
