About this study
Official title: ACT on Vaping: Digital Therapeutic for Young Adult Vaping Cessation
This clinical trial evaluates a smartphone application (app) called Acceptance and Commitment Therapy (ACT) on Vaping for helping young adults quit using electronic cigarettes (e-cigarettes). E-cigarettes pose numerous risks, particularly to youth and young adults. Addressing the high prevalence of e-cigarette use by young adults requires effective and accessible treatments to support current users to quit. Research shows this group prefers and benefits from newer methods of treatment delivery such as digital interventions. ACT on Vaping is a digital therapeutic intended to deliver behavioral therapy to young adults who vape to motivate and support abstinence from all nicotine and tobacco products. The app contains sessions that promote awareness of cues that trigger tobacco use and teach skills for responding to these triggers in a way that is tailored for the participant's readiness to quit. Receiving access to the ACT on Vaping app may be effective in helping young adults quit vaping.
Read the detailed description
OUTLINE: Participants are randomized to 1 of 2 arms.
ARM I: Participants use the ACT on Vaping app (Version A) and receive a text messaging program to motivate and support quitting. Participants also receive incentivized text message check-ins at 2 weeks, 2 months, and 4 months to assess their vaping status.
ARM II: Participants use the ACT on Vaping app (Version B) and receive incentivized text message check-ins at 2 weeks, 2 months, and 4 months to assess their vaping status.
After completion of study intervention, participants are followed up at 3, 5.5, and 6 months.

What is being measured
The primary outcome is the main question the study is designed to answer.
Cotinine-confirmed 30-day point prevalence abstinence from all nicotine and tobacco
Biochemically confirmed 30-day abstinence from all nicotine and tobacco (excluding Food and Drug Administration [FDA]-approved pharmacotherapies). Will be assessed in each individual and summarized within each group as a proportion.
Measured: At 6 months post-randomization
Secondary outcomes (5)
Self-reported 30-day point prevalence abstinence from vaping
Proportion of participants self-reporting 30-day abstinence from vaping. Will be assessed in each individual and summarized within each group as a proportion. The proportion of "success" will be compared between groups using logistic regression.
Measured: At 3 months post-randomization
Self-reported 30-day point prevalence abstinence from vaping
Proportion of participants self-reporting 30-day abstinence from vaping. Will be assessed in each individual and summarized within each group as a proportion. The proportion of "success" will be compared between groups using logistic regression.
Measured: At 6 months post-randomization
Cotinine-confirmed 7-day point prevalence abstinence from all nicotine and tobacco
Biochemically confirmed 7-day abstinence from all nicotine and tobacco (excluding FDA-approved pharmacotherapies). Will be assessed in each individual and summarized within each group as a proportion. The proportion of "success" will be compared between groups using logistic regression.
Measured: At 3 months post-randomization
Number of 24-hour quit attempts
Number of times between baseline and 3-month follow-up that participant stopped using all nicotine and tobacco (excluding FDA-approved pharmacotherapies) for 24 hours or longer. Will be assessed in each individual and summarized within each group as a continuous variable and analyzed using linear regression.
Measured: Baseline to 3 months post-randomization
Change in readiness to quit using electronic cigarettes (e-cigarettes) on the Contemplation Ladder
Self-reported motivation to quit smoking e-cigarettes (Contemplation Ladder), rated 1-10. Higher scores indicate greater motivation to quit (i.e., high [> 5] versus low [5 or less]). Will be assessed in each individual and summarized within each group as a change score and analyzed using linear regression.
Measured: Baseline to 3 months post-randomization
