Study: NCT05130788

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: WeChat Quit Coach
Description: WeChat Quit Coach intervention will be delivered via WeChat private groups for 6-12 weeks (\<30 seconds per day). During the intervention period, participants will receive a text message at a fixed point of time every day (e.g., 8:00 am). The messages are designed to build motivations and skillset to quit smoking. Participants will also receive a daily group discussion question (e.g., If you are to give one piece of advice to someone who has not made the decision to quit smoking, what would you say to his/her?), and be encouraged to respond to the question. Participants can comment on group members' responses and ask questions related to smoking and quitting either in group (so everyone in the group can see the message) or directly to the coach (so only the coach can see the message). The coach will respond to the questions within 24 hours. The PI and the RA will moderate group discussions.
