Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
During the past decade, the investigators have conducted several trials on promoting smoking cessation to smokers with chronic diseases, including cardiac, type 2 diabetes mellitus, and cancer. It is found that many smokers with chronic diseases had a long smoking history, high nicotine dependency, no quit attempt, and no intention to quit. Results of these studies indicated that about 68% smokers with cardiac diseases, 70% with diabetes mellitus and 73% with cancer recruited in Special Out-Patient Clinics (SOPC) were still in the pre-contemplation stage. This revealed that most Hong Kong smokers with chronic diseases perceived more barriers in quitting than the benefits of quitting. Nevertheless, our previous smoking cessation interventions mostly focused on using brief interventions including stage-matched smoking cessation advice. Such interventions could be too brief and inadequate to make a great impact on such smokers. Moreover, the investigators found that using strong warnings to communicate the risk of continued smoking might not be accepted by some of them. Hence, the investigators need to develop and evaluate a more innovative intervention to enhance the effectiveness in promoting smoking cessation for smokers with chronic diseases. Most importantly, the new strategy should have a good potential implementation in many clinical settings.
Smoking has been found to be associated with physical inactivity, unhealthy diet, and drinking. The interrelationship of health behaviours suggests that there could be a higher level of attribute that determines such behaviours together. Our previous studies showed that people with a general intention to promote their health are more likely to engage in desirable health-related lifestyle practices. In addition, research results showed that people once engaged in any desirable health-related lifestyle practices would progressively move to later stages of change for other health behaviours. Based on this concept, a general health promotion approach will be used to motivate smokers with intention to promote health to first engage in any desirable health-related lifestyle practices that are chosen by individual smokers, such as regular physical activity and healthy diet. It is anticipated that once they are engaged in any desirable health-related lifestyle practice they will eventually be more motivated to quit smoking.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Experimental group
The experimental group will receive individual face-to-face brief MI (about 5 minutes) on a health-related lifestyle practice. The experimental group will then receive a brief MI via WhatsApp/WeChat on a smartphone during the study period. The brief MI messages will be delivered more intensively as preferred by the subject (usually not less than once every 2 to 3 days and no more than 2 times per day) for the first 6 months. The frequency of delivering the messages via WhatsApp/WeChat will be interactive, depending on the subjects' actions and responses, and may take several sessions of chats within several days or weeks. After 6 months, minimal messages will be provided to the subjects by merely following their progress of behavioural changes and responding to their questions to maintain contact until the 1-year follow-up.
General Health Promotion Approach
The trained Research assistants will ask the subjects about the priority of engaging in any desirable health-related lifestyle practice as identified in the completed baseline questionnaires and to state a targeted goal that they perceive as the easiest to achieve. Each subject will then receive an individual face-to-face brief MI (about 5 mins) with generic health advice on selected health-related lifestyle practice. They will then be informed to receive an individual brief MI intervention to assist behavioural changes or achieve goals as desired or chosen by them via WeChat or WhatsApp in smart phones throughout the study period.
The RA will then deliver brief MI to each subject individually via WeChat or WhatsApp in smart phones throughout the study period.
Readiness of quitting smoking will be assessed at 3-month follow-up. Upon request by subjects, we shall provide them with more comprehensive information on quitting.
Control group
The control group will be given general brief advice and receive a self-help booklet on smoking cessation published by the Hong Kong Council on Smoking and Health with Hotline will be also provided in the SOPCs. The subjects in this group will receive the same schedule of follow-ups as in the intervention group, but they will not receive any follow-up booster intervention.
Control
The subjects will be given general brief advice and a self-help smoking cessation booklet with Hotline (Tel.: 1833183). However, subjects in the control group will not receive brief MI and follow-up booster intervention.
