A web application for moderation training: initial results of a randomized clinical trial

Area of Science:

• Behavioral Psychology
• Public Health
• Digital Health

Background:

• Heavy alcohol consumption presents significant public health challenges.
• Effective, accessible interventions are needed for individuals seeking to reduce drinking.
• Internet-based programs offer a scalable solution for alcohol use disorder interventions.

Purpose of the Study:

• To evaluate the effectiveness of an Internet-based Moderate Drinking protocol combined with online resources.
• To compare this combined approach against using online resources alone for heavy drinkers.
• To assess short-term outcomes in reducing alcohol consumption and related problems.

Main Methods:

• Eighty-four heavy drinkers were recruited via newspaper advertisement.
• Participants were randomized into two groups: (a) Moderate Drinking protocol + Moderation Management (MM) online resources, or (b) MM online resources alone.
• Outcomes were assessed at 3-month follow-up, including standard drinks per week, days abstinent, estimated blood alcohol concentration (BAC), and alcohol-related problems.

Main Results:

• Both groups demonstrated significant reductions in drinking frequency, quantity, and estimated BAC.
• Both groups also reported significant decreases in alcohol-related problems.
• The group using the Moderate Drinking program and MM resources showed superior outcomes in days abstinent and reduced drinking intensity compared to the MM-only group.

Conclusions:

• The Moderate Drinking Web application, in conjunction with Moderation Management resources, is effective for heavy drinkers.
• Online resources from Moderation Management alone also contribute to reduced drinking and alcohol-related problems.
• These findings support the use of digital health tools for managing heavy alcohol consumption.
