Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention
Participants will be asked to complete a 30-minute intervention that is accessible on a mobile device, delivered via a webpage, and personalized to their individual vaping behavior and beliefs (based on the baseline surveys). The intervention will contain personalized normative feedback (PNF), Motivational Enhancement (ME), and education.
Participants will complete assessments at baseline as well as 2-weeks, 4-weeks, and 8-weeks post randomization.
Live Free From E-cigarettes
This is a 30-minute online educational program that focuses on providing information about e-cigarette and smoking social norms, harms of e-cigarettes and cigarettes, and ways to quit or reduce using e-cigarettes.
Waitlist Control
Participants will complete assessments at baseline as well as 2-weeks, 4-weeks, and 8-weeks post randomization. They will not receive the intervention during the active study phase, lasting 8 weeks. Participants will have the option to access the intervention once this active study phase is over.
