Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The Coronavirus Disease 2019 (COVID-19) provided new opportunities and challenges in promoting smoking cessation. A growing literature has shown that smoking is linked to poor progression of COVID-19 (Patanavanich \& Glantz, 2020), which can be a new warning for motivating smokers to quit smoking. However, social distancing measures and increased stress and anxiety related to fear of contracting COVID-19 may increase the risk of smoking relapse in people who recently quit smoking (Patwardhan, 2020). There are also misinformation or unproven claims that smoking can protect against COVID-19. The social distancing measures also become a barrier for smokers who are interested in quitting to receive treatment from smoking cessation clinics. Therefore, implementing new interventions that can address the challenges in the context of the COVID-19 pandemic is needed.
Advance in mobile technologies provides a new avenue for delivering smoking cessation support. A qualitative interview of 21 current smokers in Hong Kong has found that mobile instant messaging app (e.g., WhatsApp) is an acceptable and feasible platform for providing chat support for smoking cessation (Luk et al., 2019). Chat-based support allows a registered nurse or trained counsellor to interact with a smoker individually through mobile instant messaging apps (e.g., WhatsApp and WeChat) and provide real-time, continuous, and personalized smoking cessation information and advice. A randomised trial of 1185 smokers found that the chat-based intervention integrated with brief intervention was effective in increasing smoking cessation (Wang et al., 2019). The trial also provided initial evidence that the intervention can be delivered as a stand-alone treatment or in combination with use of existing cessation treatment, to increase the chance of successful quitting. This study aims to adapt the chat intervention for smoking relapse prevention and evaluate its feasibility and effectiveness in recent tobacco abstainers enrolled in a clinic-based smoking cessation service in Hong Kong.

Control group
SMS message support + Self-help booklet
SMS message support
Subjects will receive regular SMS on generic smoking cessation for 3 months.
Self-help booklet
Subjects will receive a standard self-help booklet on smoking relapse prevention.
