Effectiveness of WhatsApp Online Group Discussion for Smoking Relapse Prevention: a Pragmatic Randomized Controlled Trial

The University of Hong Kong·interventional·Posted Nov 30, 2018·Updated Jul 18, 2022

In Brief

A clinical study evaluating WhatsApp group and SMS group for Smoking Cessation. Completed, enrolled 928 participants across 1 site.

Detailed 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.
