Gen AI Powered Behavioral Support Plus Chewing Gum Intervention for Construction Workers Who Smoke
Hong Kong200 participantsStarted 2026-06-20
Plain-language summary
The goal of this pilot trial is to learn if 1-week NRT sampling, 3-week chewing gum, and 12-week chatbot-delivered instant messaging support works to help smoking cessation in construction workers who smoke. It will also learn about the feasibility, acceptability, and preliminary effectiveness of delivering the comprehensive intervention in construction settings. The main questions it aims to answer are:
1. Will the integrated intervention, comprising NRT sampling, chewing gum, and chatbot-delivered instant messaging support, show feasibility, acceptability, and appropriateness for delivery in construction worksite settings?
2. Will participants who receive the comprehensive intervention have a higher validated abstinence rate than those who receive NRT sampling alone?
Researchers will compare the integrated intervention, comprising NRT sampling, chewing gum, and chatbot-delivered instant messaging support, to the standard care group (NRT sampling alone) to see if the integrated intervention works to promote smoking cessation.
Participants in the intervention group will receive:
1. AWARD advice and brief video
2. 1-week NRT sampling
3. 3-week chewing gum
4. 12-week chatbot-based instant messaging support (via WhatsApp)

Exclusion criteria
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 combines a generative AI behavioral support tool with nicotine chewing gum specifically for construction workers — given my work environment and daily routine, is this kind of combined approach something you'd think could realistically fit my situation?
2The trial isn't recruiting yet, so if I'm trying to quit smoking now, should I be looking at currently available treatments first rather than waiting to see if this study opens?
3The trial measures 'biochemically validated abstinence,' meaning they verify quit status with a physical test rather than just self-reporting — how confident are you that this kind of rigorous outcome tracking reflects real-world success rates I should expect?
4Since this is listed as Phase NA, which often means it's a behavioral or non-drug study, what does that mean for understanding the safety and effectiveness of the AI support component compared to treatments that have already gone through standard clinical trial phases?
5If this trial does open and I become eligible, would participating mean I'd have to delay or give up access to other proven quit-smoking treatments like prescription medications or established counseling programs?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.
