The control group only received the booklet. The primary outcome was the 2- and 6-month relapse rates, defined as the proportion of participants who smoked at least 5 cigarettes in 3 consecutive days. Results: Fewer participants in the WhatsApp group (17{\%}, 7/42) reported relapse than the control group (42.6{\%}, 23/54) at 2-month (OR 0.27, 95{\%} CI 0.10-0.71) and 6-month (40.5{\%}, 17/42 vs 61.1{\%}, 33/54; OR 0.43, 95{\%} CI 0.19-0.99) follow-ups. The Facebook group (30.0{\%}, 12/40) had an insignificantly lower relapse rate than the control group (42.6{\%}, 23/54) at 2-month (OR 0.58, 95{\%} CI 0.24-1.37) and 6-month (52.5{\%}, 13/40 vs 61.1{\%}, 33/54; OR 0.70, 95{\%} CI 0.31-1.61) follow-ups. The WhatsApp social groups had more moderators' posts (median 60, IQR 25 vs median 32, IQR 7; P=.05) and participants' posts (median 35, IQR 50 vs median 6, IQR 9; P=.07) than their Facebook counterparts, but the difference was insignificant. Conclusions: The intervention via the WhatsApp social group was effective in reducing relapse probably because of enhanced discussion and social support. Inactive discussion in the Facebook social group might have attributed to the lower effectiveness.
