Smoking Cessation Programme in Workplaces in Hong Kong (Phase Ⅴ)

Health talk provided information about hazards of tobacco (active smoking, second- and third-hand smoke), benefits of quitting smoking and methods to quit smoking.

Individual chat-based interactions last 3 months and consist of 2 parts. First part is regular message. The schedule will be adjusted according to the participants' quitting and mental health status. The second part includes real-time psycho-behavioral intervention delivered by trained cessation counsellors using the acceptance and commitment therapy (ACT) model for smoking cessation and reliving mental health problems. The conversation is based on participants' socio-demographic characteristics, smoking habit at baseline, and updated smoking status and mental health status assessed during online conversation and the baseline questionnaire.

Regular messages will be sent twice per month within 3 months. These messages covers simple cessation advice and reminders for follow-ups.

The intervention outcomes and participants' smoking status will be followed up regularly via telephone interviews (15 - 30 minutes).

Full course of NRT treatment (8 weeks) will be provided to all participants who are still smoking at 6-month follow-up and request, or willing to use NRT after advice from counsellors. Medications will be mailed from the smoking cessation clinics.
