Summary

Alcohol is one of the leading contributors to premature mortality and disability. Most people with alcohol problems will never seek treatment. There is a need to develop alternate ways to help problem drinkers outside of formal treatment settings.

One promising strategy is Internet-based interventions for problem drinkers. The first randomized controlled trial found that the investigators could reduce alcohol consumption by about six drinks per week at a six-month follow-up using a minimal, personalized feedback Internet-based intervention. The investigators second randomized trial demonstrated that an extended Internet-based intervention that contained a range of cognitive-behavioural and relapse prevention tools could produce greater reductions in problem drinking compared to that provided by the same minimal intervention at a six-month follow-up. Building upon this research, the current project will assess whether this extended Internet-based intervention can have a sustained impact on problem drinking. Specifically, the major objective of this project is to conduct a randomized controlled trial comparing the impact of an extended Internet-based self-help intervention for problem drinkers to a minimal Internet-based intervention in the general population of problem drinkers over a two year period.

Problem drinking participants will be recruited through media advertisements across Canada and will be randomly assigned to the minimal or extended Internet-based interventions. Six-month, twelve-month and two-year drinking outcomes will be compared between experimental conditions. It is predicted that participants receiving the extended Internet intervention will display sustained improved drinking outcomes compared to participants in the minimal Internet intervention condition. This programmatic line of research will advance the science of Internet-mediated intervention.
