Abstract
OBJECTIVE: E-cigarette use (i.e., vaping) among young adults increases the risk for significant health consequences and combustible cigarette uptake. Although there are a growing number of vaping cessation interventions for young adults, there are no known evidence-based e-cigarette use treatments that include smoking uptake prevention. The Live Free From E-Cigarettes (LIFFE) digital program was developed to help young adults stop or reduce their use of e-cigarettes and reduce their cigarette smoking susceptibility. METHOD: Twenty young adults (ages 18-24) who vape but do not smoke combustible cigarettes were recruited via social media. They completed an initial survey and the single-session, 30-min intervention on their mobile devices, followed by quantitative measures of intervention feasibility and acceptability. One week later, participants completed an interview to provide feedback about the program and a follow-up survey. RESULTS: All participants completed all seven intervention modules. Participants rated LIFFE as feasible in terms of delivery, usability, and logistics. Participants were satisfied with the content, design, and potential to help them and other young adults who vape to stop or reduce use. Some participants reported reductions in their susceptibility to smoke and vaping behaviors, including via quitting, 1 week after the intervention. CONCLUSIONS: Quantitative and qualitative results indicate that LIFFE is a feasible and acceptable program for engaging young adults in cessation efforts. Participants also included suggestions for potential changes to enhance the LIFFE program. Next steps will include building upon these suggestions for intervention refinement and testing the refined version in a randomized controlled trial.
