Résumé
Novel approaches to engage community smokers in smoking cessation are needed as smokers typically lack motivation to quit or use evidence-based tobacco dependence treatment. Mobile instant messaging apps (e.g., WhatsApp, Facebook Messenger) are widely used but under-studied as a mobile health modality for delivering smoking cessation support. This paper presents the rationale and study design of a trial which aims to evaluate the effectiveness of a chat-based intervention using mobile instant messaging combined with brief interventions for community smokers. This is a two-arm, parallel, accessor-blinded, pragmatic cluster-randomized controlled trial on an estimated 1172 daily cigarette smokers aged ≥18 years proactively recruited from 68 community sites (cluster) throughout Hong Kong. Subjects in intervention group received three months of chat-based, instant messaging support guided by acceptance and commitment therapy and other behavioural change techniques, integrated with brief advice and active referral to a smoking cessation service using the AWARD (Ask, Warn, Advise, Refer, Do-it-again) intervention model. Control group received brief advice to quit plus a self-help booklet at baseline. Outcomes were assessed at 1-, 2-, 3- and 6-month after baseline. The primary outcome is abstinence validated by exhaled carbon monoxide (<4 ppm) and salivary cotinine (<10 ng/mL) at 6-month after baseline. Primary analyses will be based on intention-to-treat. This is the first trial examining the effectiveness of a chat-based cessation support programme combined with brief interventions in promoting abstinence. The intervention model can be adapted for other behavioural change treatments and more advanced digital smoking cessation intervention.

BACKGROUND
Novel approaches to engage community smokers in smoking cessation are needed as smokers typically lack motivation to quit or use evidence-based tobacco dependence treatment. Mobile instant messaging apps (e.g., WhatsApp, Facebook Messenger) are widely used but under-studied as a mobile health modality for delivering smoking cessation support. This paper presents the rationale and study design of a trial which aims to evaluate the effectiveness of a chat-based intervention using mobile instant messaging combined with brief interventions for community smokers.
METHODS
This is a two-arm, parallel, accessor-blinded, pragmatic cluster-randomized controlled trial on an estimated 1172 daily cigarette smokers aged ≥18 years proactively recruited from 68 community sites (cluster) throughout Hong Kong. Subjects in intervention group received three months of chat-based, instant messaging support guided by acceptance and commitment therapy and other behavioural change techniques, integrated with brief advice and active referral to a smoking cessation service using the AWARD (Ask, Warn, Advise, Refer, Do-it-again) intervention model. Control group received brief advice to quit plus a self-help booklet at baseline. Outcomes were assessed at 1-, 2-, 3- and 6-month after baseline. The primary outcome is abstinence validated by exhaled carbon monoxide (<4 ppm) and salivary cotinine (<10 ng/mL) at 6-month after baseline. Primary analyses will be based on intention-to-treat.
COMMENTS
This is the first trial examining the effectiveness of a chat-based cessation support programme combined with brief interventions in promoting abstinence. The intervention model can be adapted for other behavioural change treatments and more advanced digital smoking cessation intervention.
