简要总结
The goal of this quasi-experimental study is to test if a smartphone app can help adolescents aged 14-20 quit e-cigarettes. The main questions it aims to answer are:
- Can the app help adolescents manage cravings and increase their readiness to quit?
- Does the personalized and real-time support provided by the app improve their success in quitting e-cigarettes?
Researchers will compare two groups: an immediate-intervention group that starts using the app right away and a delayed-intervention group that begins after three months, to see if the timing of app access influences outcomes in e-cigarette cessation.
Participants will:
- Set personal goals and track their daily progress within the app.
- Use a real-time "urge" feature that provides immediate support during cravings.
- Engage with a chatbot for quick answers and motivational support around quitting.
This study aims to create an accessible, personalized tool to help adolescents reduce or quit e-cigarette use, exploring its feasibility as a broader intervention model.
详细描述
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.

研究组 & 干预措施
Immediate-Intervention Group
Participants in this arm will begin using the AI-enhanced smartphone app immediately after enrollment. This arm serves to assess the initial impact and feasibility of the app as a tool for e-cigarette cessation among adolescents.
干预措施: AI-enhanced smartphone app (Behavioral)
Delayed-Intervention Group
Participants in this arm will wait three months after enrollment before using the AI-enhanced smartphone app. This arm serves as a delayed control, allowing comparison with the immediate-intervention group to understand the impact of timing on quitting success.
干预措施: AI-enhanced smartphone app, but with delayed access (Behavioral)
结局指标
主要结局
Usability
时间窗: 30-Day Follow-up
The usability of the intervention will be assessed using the mHealth App Usability Questionnaire, a 21-item instrument designed for interactive mobile health apps. It measures three domains: ease of use and satisfaction, system information arrangement, and usefulness. Each item is rated on a 5-point Likert scale, yielding a total score range of 21 to 105, with higher scores indicating better usability. An open-ended question will also be included at the end of the survey to gather suggestions for app improvement.
