Plain English Summary
Background and study aims
The e-health portal on alcohol and health of the World Health Organization was launched on December 6, 2012. So far there are adapted versions in four countries and four different languages (https://www.infoalcohol.net/, https://www.informalcool.org.br, https://www.alcoholwebindia.in, https://www.saberdealcohol.org.mx/). This portal provides information for policymakers, professionals and the public at large on alcohol and health. It also includes a web-based self-help program to reduce alcohol consumption. Testing the effectiveness of this self-help program is the first step to open the program to other countries worldwide and make it more attractive for authorities in countries not yet involved. The potential public health impact of the expansion of an effective Internet self-help program to many low-income and high-income countries worldwide is enormous. The aim of this study is to test the effectiveness of the web-based self-help program to reduce alcohol consumption.
Who can participate?
People aged between 18 and 75 who live in Brazil, India, Mexico or Belarus.
What does the study involve?
Participants are randomly allocated to one of two groups. One group is given access to the Alcohol e-Health program, while the other group receives general information on alcohol and health, and is given access to the Alcohol e-Health program after the end of the study.
What are the possible benefits and risks of participating?
Participants may learn to reduce or to abstain from alcohol use by participating in the six-week self-help program. According to the experience in former studies, there are no significant health risks in participating in this' study. However, in case participants experience acute alcohol withdrawal or other physical or mental symptoms, they are recommend to see a health professional.

Scientific title
Alcohol e-Help – a web-based self-help program for the reduction of alcohol use in harmful, hazardous or suggestive dependent drinkers compared to an active waiting list: a cluster randomized controlled four-country trial
Acronym
Study hypothesis
The study hypothesizes that participants in the Alcohol e-Health program will show greater reductions in the Alcohol Use Disorders Identification Test score (AUDIT, primary outcome, Babor et al. 2001) at the 6-month follow-up than participants allocated to a waiting list control group. Similar hypotheses are drawn regarding secondary outcomes, the quantity of alcohol measured in weekly standard drinks and the number of alcohol abstinent days of a typical week in the last 6 months. Participants in the program group are also expected to be less harmful or hazardous drinkers (falling below the cut-off of 8 according to the AUDIT score, Babor et al. 2001) at the 6-month follow-up.
Ethics approval

Condition
Harmful, hazardous or suggestive dependent alcohol users
Intervention
The randomization occurs on the individual level but for each country separately. Participants are randomized to either:
1. The Alcohol e-Health program
2. Classical waiting list receiving first general information on alcohol and health and program access only after 6 months
The Alcohol e-Health program is an accessible self-help tool for people who are trying to reduce their use of alcohol or stop drinking entirely. Participants can register and use the program in their own time, at their own pace, and free of charge. Participants are encouraged to complete all parts of the program, to repeat any parts they feel they need or perceive as helpful, and to use the program for a minimum of 6 weeks. Alcohol e-Health provides support for individual participants to think about their drinking, decide whether or not to change their drinking, set goals regarding their drinking, take action regarding reducing or stopping drinking, measure their progress, and to deal with relapse to their previous drinking patterns.

Primary outcome measure
The total score of the Alcohol Use Disorders Identification Test (AUDIT, Babor et al. 2001) will be assessed at baseline and the 6-month follow-up
Secondary outcome measures
1. Falling below the cut-off of hazardous or harmful alcohol use (below AUDIT score of 8) between baseline and the 6-month follow-up
2. The alcohol use reflected for each weekday of a typical week in the last six months assessed at baseline and the 6-month follow-up
3. Program satisfaction is measured by the Client Satisfaction Questionnaire CSQ-8 assessed at the 6-months follow-up in the intervention group only
