This quasi-experimental study aims to develop and evaluate an AI-enhanced smartphone app
designed to support adolescents aged 14-20 in quitting e-cigarettes. Given the high
prevalence of e-cigarette use among youth, this app-based intervention focuses on
providing personalized, real-time support for cravings and motivation to quit. The app
integrates interactive features to engage users and is designed for scalability, enabling
wide-reaching impact in various settings such as schools, clinics, and communities.
Study Phases and Objectives
Phase 1: Development and Usability Testing Phase 1 focuses on refining an existing beta
version of the app. In this formative stage, the app's design, content, and features will
be adjusted based on adolescent feedback to ensure it is user-friendly and engaging.
Participants will test the app and provide insights through usability surveys and
interviews, which will inform necessary changes.
Key activities in this phase include:
Gathering feedback on usability and design.
Modifying app features to better meet the preferences and needs of adolescent users.
Finalizing the app to meet high usability benchmarks for deployment in the next
phase.
Phase 2: Clinical Feasibility Testing In Phase 2, the app's effectiveness will be tested
using a quasi-randomized design with two groups: one group of participants will begin
using the app immediately, while the second group will start after a three-month delay.
This approach will help determine if earlier access to the intervention leads to improved
outcomes in terms of e-cigarette cessation.
The study will assess how the app impacts participants' readiness to quit, actual
quitting attempts, and ongoing motivation over time. Engagement levels with the app's
features, such as real-time craving support and AI-driven educational modules, will also
be tracked to evaluate the intervention's overall feasibility and appeal.
App Features and Personalization
The app's core features include:
Goal Setting and Progress Tracking: Users set personal quitting goals, track their
progress, and access daily training modules to build skills for managing cravings
and quitting.
Real-Time Craving Management: The "urge" feature provides immediate support during
cravings, using mindfulness exercises and coping strategies tailored to each user's
needs.
AI Chatbot Support: A chatbot offers 24/7 assistance, answering questions and
providing motivation based on users' quitting status and individual characteristics.
These AI-driven tools are customized according to user data and interactions within the
app, ensuring the intervention feels personal and responsive to each user's progress.
Data Collection and Analysis Data will be collected on app usage, engagement with
specific features, and changes in e-cigarette use over time. Analysis will include both
user feedback and statistical evaluation of the app's impact on participants' quitting
success. Insights from this data will contribute to the ongoing refinement of the app and
inform its potential for broader use as an adolescent-focused e-cigarette cessation tool.
Anticipated Impact This study aims to create a user-friendly, scalable app that leverages
AI to support adolescents in quitting e-cigarettes effectively. If successful, this
digital intervention could be a valuable resource for youth cessation programs and serve
as a model for similar health-related app-based interventions.
