Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Primary hypothesis: The Intervention group has significantly larger reduction of weekly alcohol consumption compared with the Control group at 12-month follow-up
Secondary hypotheses: Compared with the Control group, the Intervention group has lower AUDIT scores, fewer episodes of heavy/binge drinking, lower re-attendence at AED and reduced alcohol-related harms at 6-month and 12-month follow-up.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention group
Alcohol brief intervention, leaflets, regular personalized messages on ABI through IM Apps, real-time chat-based support through IM Apps
Alcohol brief intervention
At baseline, subjects will receive face-to-face or online alcohol brief intervention developed based on the guideline by the World Health Organisation in 5-10 minutes
12-page health warning leaflet
Nurses will provide information about the consequences of drinking using a 12-page health warning booklet. Benefits of reducing and quit drinking will be emphasized by focusing on improving their perception towards the impacts on health, social problems, risky behaviors, academic performance and financial issues.
Regular messages through Instant Messaging (IM)
A total of 26 e-messages will be scheduled: once daily for the first week, 3 time/week for subsequent 4 weeks and 1 time/week for the remaining 7 weeks. The frequency will be adjusted according to IM Apps conversation and subject's requests.
Real-time chat-based support through IM Apps
The chat-based IM support is the extension of baseline ABI and regular e-messages, which aims to provide real-time behavioral and psychosocial support to reduce or quit drinking. It will be personalized according to the subjects' characteristics (gender, drinking pattern and alcoholic drinks preferences), intention to drink and specific questions regarding drinking. Through real-time chatting (text and/or voice), drinkers can acquire information on consequences of drinking and gain social support immediately to reduce intention to drink and alcohol consumption.
