Clinical Trial Summary

The goal of this intervention development and pilot clinical trial is to determine whether receiving the brief online intervention results in greater reductions in past 7-day e-cigarette use frequency and smoking susceptibility over an 8-week period compared to receiving the control condition in young adults who currently use e-cigarettes. Participants in the experimental condition will be asked to complete the 30-minute mobile-based program. Participants in the assessment-only control will be given the option to access the intervention after they complete their final survey at 8 weeks. All participants will complete our online surveys at baseline as well as 2-weeks, 4-weeks, and 8-weeks post-randomization. Researchers will compare outcomes among the intervention and control groups to determine the efficacy of the intervention.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	E-cigarette Use	Participants will report the number of (1) days they vaped, (2) times they picked up their device to vape per day, and (3) puffs they took before putting their vaping device away per day in the past 7 days and 30 days	8 weeks
Primary	Smoking Susceptibility	4-item Expanded Susceptibility to Smoking Index (ESSI)	8 weeks
Secondary	Perceived harms and benefits of vaping	Using the 21-item Short Form Vaping Consequences Questionnaire (S-VSQ), participants will rate the likelihood that each consequence will occur when they vape.	8 weeks
Secondary	Perceived harms and benefits of smoking	Using the 21-item Short Form Smoking Consequences Questionnaire (S-SCQ), participants will rate the likelihood that each consequence will occur when they smoke.	8 weeks
Secondary	Motivation to vape	Participants will select which option best describes their interest in e-cigarette use: plan to stop (coded as 1), decrease (2), continue (3) or increase (4) vaping.	8 weeks
Secondary	Motivation to smoke	Participants will report if they plan to start smoking (yes/no).	8 weeks
Secondary	Quitting vaping self-efficacy	Participants rate their confidence about quitting vaping "someday" and "in the next 6 months" on a 5-point scale.	8 weeks
