A randomized controlled trial of an internet-based intervention for alcohol abusers

Area of Science:

• Public Health
• Behavioral Science
• Digital Health

Background:

• Alcohol misuse represents a significant public health burden.
• Traditional in-person services for alcohol abuse have limited reach among problem drinkers.
• Brief, accessible interventions are needed for individuals unwilling or unable to seek traditional treatment.

Purpose of the Study:

• To evaluate the efficacy of the internet-based Check Your Drinking (CYD) screener.
• To assess CYD's impact on alcohol consumption in problem drinkers.
• To determine the public health benefit of accessible online alcohol interventions.

Main Methods:

• A randomized controlled trial was conducted.
• 185 participants were recruited via a telephone population survey.
• Participants were randomly assigned to either the CYD intervention or a no-intervention control group.

Main Results:

• Excellent follow-up rates (92%) were achieved.
• Problem drinkers accessing CYD showed a 30% reduction in weekly alcohol consumption (6-7 drinks).
• Control group participants showed only a one-drink reduction per week at 3- and 6-month follow-ups.

Conclusions:

• The Check Your Drinking (CYD) screener is an effective internet-based intervention for reducing alcohol consumption.
• Online interventions can expand help-seeking options by bringing treatment to the individual.
• CYD demonstrates research-supported efficacy, offering a scalable solution for alcohol misuse.
