Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Design and subjects: The RCT study will randomize participants into the intervention group or the control group. Prior to randomization, a baseline telephone survey will be conducted. Phone interviews will be conducted to evaluate the outcomes at Months 3 and 6 after completion of the intervention. Interviewers will be blinded from the randomization status. The inclusion criteria are: i) current smokers who have smoked at least one cigarette in the past seven days prior to the baseline survey, ii) age 18 years old or above, iii) able to communicate in Chinese (Cantonese), iv) having access to a smart phone or mobile electronic devices and social networking media (WeChat), v) willing to be followed up (Months 3 and 6), vi) should own a smart phone or a similar device.
Study instruments: Structured questionnaires.
Interventions: The 2-month intervention includes i) interactive online support groups and ii) immediate preventive 'SOS' cue to action messages to be sent to fellow support group members in need via WeChat. Besides, basic health education messages will be sent to both the intervention and the control groups.
Main outcome measures: self-reported 7-day point prevalence (pp) quit rate of smokers at 6 months post end-of-intervention.
Data analysis and expected results: Baseline characteristics between the two groups will be compared using t-test and chi-square test as appropriate. To evaluate efficacy in terms of the primary outcome, absolute risk reduction (ARR), relative risk reduction (RRR) and number needed to treat (NNT) at Months 3 and 6 and their 95% confidence intervals will be derived. Mixed effects models will be used to compare the differential changes on the outcome variables across the time points Months 0, 3 and 6 between the two study arms with adjustment for potential confounding variables. Significance differences in smoking cessation will be found among the two groups.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
WeChat interactive peer support group
Participants will be grouped together by the researcher to form closed online peer support groups (with group names they choose). Activities on the WeChat groups serve two functions: i) It enhances social support among peer members toward smoking cessation. ii) The online support group also enhances the participants' positive affect.
Basic health education messages
Messages containing basic health education materials, including perceived severity of smoking, perceived benefit of smoking cessation and tips on resisting situational temptations will be sent to the participants of both arms through WeChat after randomization takes place.

Basic health education messages
Members of the control group will receive health education messages that will also be sent to the intervention group through WeChat. The messages include topics on physical and psychological aspects of perceived severity of smoking and perceived benefits of smoking cessation, and tips/skills on resisting situational temptations that may lead to relapse.
