Text Message Quit Vaping Intervention for Young Adults

Not Applicable

Completed

Brief Summary: This research study, conducted by Truth Initiative, will help us learn how text messaging can help young adults between 18 and 24 years of age quit vaping.

Detailed Description: The Quit Vaping Study (QVS)'s primary aim is to conduct a fully powered comparative effectiveness trial to evaluate the effectiveness of a quit vaping text message program in promoting abstinence from e-cigarettes among young users aged 18-24. This study is a 2-arm randomized controlled trial conducted among young users aged 18-24 recruited through online channels. Participants will be randomized to a quit vaping text message intervention or to an assessment-only control condition and followed for 7 months to roughly correspond to 6-months post-treatment. The secondary aim is to examine potential mediators of program effectiveness, including treatment engagement and changes in self-efficacy and perceived social support for quitting.

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.
