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.
