Preventing binge drinking: Communication and education tools for the public and high-risk groups

In 2022, GreyBay Institute completed the commissioned policy report Communication and education tools for the public and people with alcohol-related problems: a review of interventions to prevent binge drinking for Japan's National Institute of Public Health. The report synthesised 21 systematic reviews and meta-analyses published between 1997 and 2022 and assessed interventions across the full spectrum from brief face-to-face support to digital delivery, covering both short- and long-term follow-up.

1. Research framework and main findings

The review grouped interventions into short-term programmes (within one year) and longer-term programmes (beyond one year), and mapped evidence separately for young adults, older adults, and the general adult population.

(1) Young adults aged 19-25. Evidence was strongest for this group. Brief interventions involving one to five contacts showed small but consistent benefits in reducing alcohol consumption and alcohol-related problems, with effects lasting up to one year. Motivational interviewing worked particularly well in settings such as emergency departments, while computerised interventions stood out for fidelity, standardisation, privacy, and cost-effectiveness. In longer follow-up studies, family-strengthening approaches showed increasing protective effects over time.

(2) Older adults aged 60 and above. Older adults are more physiologically sensitive to alcohol and often use prescription medications, making them especially important for prevention. The review found positive effects both for brief interventions, such as motivational interviewing, physician advice, and mailed feedback, and for more intensive programmes that combined personalised reports, educational tools, diaries, and telephone counselling. One important policy implication was that simply raising the issue of drinking with older adults may itself have intervention value.

(3) General adult population. Earlier meta-analyses showed that heavy drinkers receiving brief interventions were roughly twice as likely to reduce consumption after 6-12 months as those receiving no intervention. Nurse-delivered interventions performed especially well, and lower-dependence help-seekers benefited most. Internet-based cognitive behavioural therapy also showed promise, particularly when therapist-guided. Promising behaviour-change components included behavioural feedback, problem-solving, goal setting, cue avoidance, decisional balance, and self-monitoring.

2. Policy translation and tool-development recommendations

(1) For young people. GreyBay recommended building a three-tier prevention network across campuses, communities, and digital platforms. Validated digital interventions such as eCHECKUP TO GO and AlcoholEdu could be adapted for Japanese users and integrated into university health modules, while motivational interviewing and personalised normative feedback tools could be incorporated into occupational health checks for younger workers.

(2) For older adults. The report recommended embedding alcohol risk communication into care-prevention services, adding health-education content on alcohol, medication use, and age-related tolerance in community support centres, and introducing age-adapted tools such as CARET into health screening for older adults.

(3) For the wider adult population. The report proposed using insurance and clinical data to build risk-prediction models, delivering smartphone-based behaviour-change tools to medium-risk groups, and referring higher-risk adults to remote cognitive behavioural therapy pathways linked to specialist mental-health services. Quarterly digital maintenance support was recommended to counter the common decline in effects after initial intervention.

3. Evidence gaps and next steps

The review identified several priority gaps now included in the commissioner's next alcohol-policy evidence agenda: life-course studies of drinking in older adults; the role of family and social networks in successful reduction; culturally adapted brief interventions in low- and middle-income settings; the optimal dose and duration of digital interventions; and the real-world implementation and cost-effectiveness of workplace alcohol programmes.

This report forms part of GreyBay's broader programme on addiction behaviour and health policy. The team is now contributing to a Japanese implementation-science project on workplace alcohol policy and has launched a cross-national East Asian cohort in collaboration with The Chinese University of Hong Kong and the National University of Singapore.
