An Online Intervention to Reduce E-cigarette Use and Cigarette Smoking Risk in Adolescents
An Online Intervention to Reduce E-cigarette Use and Potential for Cigarette Smoking in Adolescents
The goal of this clinical trial is to learn if a brief digital intervention can reduce e-cigarette use and prevent cigarette smoking initiation in teenagers ages 12-17. The main questions it aims to answer are:
- Compared to the control condition, does the intervention reduce e-cigarette use frequency in teenagers?
- Compared to the control condition, does the intervention reduce risk to start smoking cigarettes in teenagers? Researchers will compare the digital intervention to see if it leads to greater reductions in e-cigarette use and smoking risk than a waitlist control condition.
Participants will complete 5 brief online surveys across 12 weeks, and some will be selected to do a post-intervention virtual interview. In this interview, participants will be asked to share their opinions about the intervention and identify areas that need refinement.

Experimentální: Digital vaping intervention
Virtual Intervention for Behavioral Empowerment (VIBE) is a one-time 30-minute online intervention that incorporates Personalized Normative Feedback (PNF) for vaping and smoking, motivational enhancement to encourage healthy behavior change, and vaping and smoking-related harms education.
Lastly, strategies recommended for nicotine cessation are presented.
This intervention can be completed in one sitting or split into multiple sessions and is delivered via an interactive website.
|
The intervention contains Personalized Normative Feedback (PNF), motivational interviewing (MI), and education about vaping and smoking harms.
The program begins with the MI-based portion, which includes exploration of their experienced health and personal consequences of vaping and potential reasons for and motivation for shifting vaping behaviors (e.g., to save money, to be free from addiction).
Second, the education portion involves presentation of the actual harms posed by e-cigarettes to clarify any misperceptions of the negative effects of vaping and nicotine exposure in teens.
Next, users are presented with the PNF portion.
In the PNF portion, participants receive feedback about their perceptions of peer vaping by presenting their typical behavior/attitude alongside their perceptions of others' behavior/attitude alongside the actual norm of the behavior/attitude.
Lastly, strategies recommended for nicotine cessation are presented.

Žádný zásah: Waitlist control
