Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Outcome:
The primary outcome of the study is to measure participated smokers' self reported 7-day point prevalence quit rate at 6-month follow-up. Secondary outcomes include participated smokers' (i) self reported 7-day point prevalence quit rate at 9- and 12-month follow-ups; (ii) self-reported reduction rate at 6-, 9- and 12-month follow-ups; (iii) self-reported quit attempt at 6-, 9- and 12-month follow-ups; (iv) change in self-efficacy towards smoking cessation at 6-, 9- and 12-month follow-ups compared with baseline.
Data analyses
Phase I:
Descriptive statistics will be used to measure the (1) basic information of the corporations, including the total number of employees and smoking employees; (2) knowledge on smoking of employers/managerial staff; (3) attitudes on smoking cessation of employers/managerial staff; (4) practices of the corporations with respect to smoking cessation.
Phase II:
Descriptive statistics such as frequency, percentage, and mean will be used to summarize the outcomes and other variables. Chi-square tests and t-tests will be used to compare outcome variables between subgroups. The intention-to-treat analysis will be used such that those lost to contact and refused cases at the follow-ups will be treated as no reduction in cigarette consumption nor quitting. Subgroup analyses will be conducted among the "adherence" cohort, which is classified as subjects who actively participant in the WhatsApp interaction.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
WhatsApp interaction
Individual and group chat interactions.
Occupational-specific health talk
Health talk will provide information about hazards of tobacco (active smoking, second- and third-hand smoke), benefits of quitting smoking and methods to quit smoking.
WhatsApp interaction
Individual WhatsApp interactions last 3-month and consist of 2 parts. First part is regular WhatsApp message. The schedule will be adjusted according to the participants' quitting status. Second part is real-time discussion intervention based on participants' socio-demographic characteristics, smoking habit at baseline and updated smoking status obtained during online conversation. At 3-month follow-up, participants who are still smoking are encouraged to join an additional 1-month online group chat moderated by a smoking cessation counselor.
Phone follow-up/counselling service
The intervention outcomes and participants' smoking status will be followed up regularly via telephone interviews (15 - 30 minutes).
Text message
Regular text messages with similar frequency to those in the Intervention group.
