AbstractBackground: Novel approaches to engage community smokers in smoking cessation are needed as smokerstypically lack motivation to quit or use evidence-based tobacco dependence treatment.Mobile instant messaging apps (e.g., WhatsApp, Facebook Messenger) are widely usedbut 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 evaluatethe effectiveness of a chat-based intervention using mobile instant messaging combinedwith brief interventions for community smokers. Methods: This is a two-arm, parallel, accessor-blinded, pragmatic cluster-randomized controlledtrial on an estimated 1172 daily cigarette smokers aged ≥18 years proactively recruitedfrom 68 community sites (cluster) throughout Hong Kong. Subjects in intervention groupreceived three months of chat-based, instant messaging support guided by acceptanceand commitment therapy and other behavioural change techniques, integrated with briefadvice and active referral to a smoking cessation service using the AWARD (Ask, Warn,Advise, Refer, Do-it-again) intervention model. Control group received brief adviceto 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 exhaledcarbon 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 supportprogramme combined with brief interventions in promoting abstinence. The interventionmodel can be adapted for other behavioural change treatments and more advanced digitalsmoking cessation intervention.
