Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
We expect that this study result would demonstrate the main effects of the interventions, including mHealth text messaging, and online platform hub. By analyzing those intervention results, we could deeply understand the effective methods to lower the risk of young adult binge drinking phenomenon. We could provide more precise interventions to secondary school students. This study will also prepare for future RCTs to explore the possibility on the integration of other intervention components or factors for binge drinking prevention research. In the long run, the proportion of binge drinking in population and young-aged will be lowered. Department of Health or other future research could implement this intervention as a fundamental to enhance the effectiveness of the alcohol control intervention.
A pilot 2-arm, parallel, open-labelled randomized controlled trial randomly allocated participants (1:1 ratio) to intervention and control groups. The intervention group has 2 intervention components: (1) Online information hub (compulsory: game), (2) mHealth text messaging at last to people who needed (Audit score \>7). The control group will receive self-help materials during the same period. The sample size is 100 participants (50 for each group).
100 ever-drinkers will be recruited from the secondary schools through online and offline. Study information will be disseminated via online advertisements, mass emails, and in-person interactions at schools in various districts, including New Territories, Kowloon, and Hong Kong Island. Interested participants can enroll by completing an online application form using Qualtrics or Google form).
During offline recruitment sessions, staff will approach secondary school students and their parents (if the participants are under 18 years old) to obtain consent and have them complete a baseline questionnaire for further contact and intervention delivery.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention group
The treatment package includes both optional and mandatory treatments. The mandatory treatments consist of mHealth text messaging and an online platform hub.
Online platform hub and mHealth Text Messaging
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.
Control Group
The 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.
Self-help material
Self-help material like leaflet is a common method used in preventing teenage Drinking.
