Control Group
ACTIVE COMPARATORThe control group will be provided a self-help material like leaflet for alcohol reduction, which involves education on alcohol harm and strategies for alcohol reduction.
Interventions
The treatment package includes both optional and mandatory treatments. The mandatory treatments consist of mHealth text messaging and an online platform hub. We have developed a game which educates teenagers about alcohol reduction and promotes awareness of alcohol-related harm. Designed to be both engaging and informative, the game uses real-life scenarios, interactive storytelling, and decision-based gameplay to help young people understand the risks of excessive drinking. Also, participants with Audit Score \> 7 will receive individualized chat-based instant text messages from WhatsApp for 8 weeks. They will have real-time and one-to-one interaction. The conversation intensity depends on the participants' need.
Self-help material like leaflet is a common method used in preventing teenage Drinking.
