Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Mental health problems are commonly comorbid with smoking and related problems. Our population-based survey amidst the COVID-19 pandemic found current smokers were at higher risk of suffering from anxious symptoms (adjusted OR 1.84 95% CI 1.27, 2.67), depressive symptoms (adjusted OR 2.04 95% CI 1.40, 2.96), and stress symptoms (adjusted β 0.54 95% CI 0.26, 0.82) compared with non-smokers. We also observed mental health burden increased during the COVID-19 pandemic with approximately doubling of the prevalence of anxious symptoms (15.8 vs. 9.3) and depressive symptoms (14.8 vs. 6.3) compared with the pre-COVID-19 pandemic (2017). Mental health can be both precursors and consequences of smoking. Previous studies have suggested that depressive symptoms and low positive affect during and after SC attempts are associated with poor cessation outcomes. This implies that a combined intervention of behavioral and psychological SC intervention is needed, particularly under the circumstance of worsening mental health problems.
Therefore, our study aims to test the effectiveness of a combined intervention using brief cessation advice and personalized chat-based positive psychological support compared with the control group on current smokers who join the Quit to Win Contest.

Intervention group
AWARD advice
Ask about smoking history; Warn about the high risk; Advise to quit; Refer smokers to smoking cessation services (with a referral card); Do it again
Brief leaflet on health warning and smoking cessation
The contents of the leaflet include (1) highlights of the absolute risk of death due to smoking; (2) the whole list of diseases caused by active and second-hand smoking; (3) ten horrible pictorial warnings of health consequences of smoking and second-hand smoking in one page to maximize the impacts; (4) benefits of SC and (5) simple messages to encourage participants to quit smoking and remind them to call the Department of Health SC hotline 183 3183.
Referral card
The contents consist of brief information and highlights of existing SC services, contact methods, motivation information, and strong supporting messages or slogans.
Self-help smoking cessation booklet
The contents include information about the benefits of quitting, smoking and diseases, methods to quit, how to handle withdrawal symptoms, declaration of quitting, etc.
Positive psychological support through 3-people group chat using instant messaging apps
Each IM chat group will consist of a trained SC counselor (HKU staff), a peer supporter (former smoker), and a participant (smoker). The 3-month group chat-based intervention will consist of regular messages and real-time support through group chat. Regular messages will generally include goal setting, health warnings, abstinence support, positive psychological exercises, and encouragement and will be delivered in a tapering style. During the real-time chatting, SC counsellors and peer supporters will provide real-time chat-based support, and peer supporters will share their quitting experience as appropriate.
