Treatments tested in this trial
Metaphor-based smoking cessation intervention
BehavioralParticipants will receive a 100-day, WeChat-delivered smoking cessation intervention using metaphors such as "fog" and "restart" to describe smoking urges, nicotine dependence, and the process of behavior change. The intervention will provide staged messages on smoking-trigger identification, self-monitoring, action planning, coping strategies, environmental modification, social support, and relapse prevention, together with personalized feedback and a personalized journey map to help participants review their cessation experiences and progress.
5A's/5R's advice
BehavioralThe 5A's approach (Ask, Advise, Assess, Assist, and Arrange) will be used for participants who are ready to quit, and the 5R's approach (Relevance, Risks, Rewards, Roadblocks, and Repetition) will be used for participants who are not ready to quit.
Health warning leaflet
Other interventionThe health warning leaflet provides essential information on the dangers of secondhand and thirdhand smoke. It outlines how exposure to these forms of smoke can harm both smokers and non-smokers, particularly children, by increasing the risk of respiratory illnesses and other health issues.
