Promoting Smoking Cessation in the Community Via "Quit to Win" Contest 2026: Engagement-Focused GenAI-based Chatbot for Real-Time Smoking Cessation Support
Hong Kong998 participantsStarted 2026-06-20
Plain-language summary
The goal of this trial is to learn if chatbot-based instant messaging works to help smoking cessation in general adult smokers. It will also learn about the experience, attitude, and perception of using an LLM-based chatbot. The main questions it aims to answer are:
1. Will an engagement-focused LLM-based chatbot smoking cessation intervention have a non-inferior validated abstinence rate than the control group?
2. Will an LLM-based chatbot smoking cessation intervention have a non-inferior self-reported abstinence rate, smoking reduction rate, and smoking cessation services use rate than the control group?
Researchers will compare an LLM-based chatbot smoking-cessation intervention to a human-led instant messaging support group (brief advice based on AWARD and personalised active referral) to determine whether chatbot-based instant messaging support promotes smoking cessation.
Participants in the intervention group will receive:
1. AWARD advice
2. Personalised active referral
3. 12 weeks of chatbot-based instant messaging support (via WhatsApp)

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial uses an AI-based chatbot for real-time smoking cessation support — how does getting help from a chatbot compare to other proven methods like counseling or medication that you might recommend for me?
2The trial isn't recruiting yet, so there could be a wait before I could even join — given where I am with my smoking right now, does it make sense to start another cessation approach in the meantime rather than waiting?
3The study measures 'biochemically validated abstinence,' which means they'll confirm quitting through a physical test — what does that process actually involve, and is it something I'd be comfortable with?
4Since this is listed as Phase NA, meaning it may be more of a behavioral or community study than a drug trial, what is still unknown about whether this chatbot approach actually helps people quit compared to standard support programs?
5This trial is part of a 'Quit to Win' community contest format — do you think a competition-style or AI-driven program fits my personality and situation, or would a different quit strategy work better for me?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
