Summary

This study aims to assess the effectiveness of chat-based intervention on reducing risky alcohol consumption to inform clinical practice for providing ABI to risky drinkers attending AED in Hong Kong.

Conditions

  • Alcohol Misuse

Interventions

BEHAVIORAL

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

BEHAVIORAL

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.

BEHAVIORAL

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.

BEHAVIORAL

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.

BEHAVIORAL

AUDIT score interpretation sheet adapted from the Department of Health of Hong Kong

a diagram explaining drinking behaviour and potential health risks, definitions of "alcohol unit" and "binge drinking", and advise on limiting daily drinking to 2 alcohol units for men and 1 unit for women
