Summary

This study aims to examine the effectiveness and cost-effectiveness of WhatsApp group discussion for smoking relapse prevention. To assess the effect due to treatment modality through the WhatsApp social group, the frequency and topics of the posts in each social group will be analysed and in each participant. The primary hypothesis is whether quitters who participate in the WhatsApp group discussion will have a higher prevalence of validated tobacco abstinence at 12-month follow-up than those who do not. The second hypothesis is that greater participation in the social groups, indicated by number of posts received, posted and/or viewed, was associated with higher likelihood to quit at 12-month. The third hypothesis is that the WhatsApp intervention for a recent quitter is a more cost-effective option for tobacco abstinence and prolonged survival when compared to the control group.
