An Internet Intervention for Alcohol Problems With or Without Assistance From a Health Educator

Using Assistance From a Health Educator to Increase Effectiveness of an Internet Intervention for Alcohol Problems. A Randomized Controlled Trial

The purpose of this study is to determine whether an internet intervention for alcohol problems is more effective when delivered with assistance from a health care educator via e-mail during the first two weeks after randomization, as compared to simply providing the intervention without any such assistance.

This project aims to study the previously evaluated multi-module internet intervention Alcohol Help Center delivered with assistance from a health educator (AHC+A). The assistance will be in the form of email contact with the participant during the first two weeks after randomization. AHC+A will be tested against a group receiving access to the intervention without any such assistance (AHC).

The Investigators hypothesize that

1. participants allocated to AHC+A will display significant reductions in drinking (drinks preceding week/heavy drinking days preceding week) in 3- and 6-month follow ups compared to AHC
2. participants allocated to AHC+A will display greater engagement with the intervention in terms of a higher number of modules completed compared to AHC
3. engagement with the intervention will mediate any effects on drinking behavior.

A 2-arm parallel group randomized controlled trial will be used to test these specified hypotheses. Follow-ups will be conducted at 3 and 6 months after randomization. Online media advertisements will be used to recruit people with current alcohol problems, and will target people who are 'experiencing difficulties in controlling or cutting down on their drinking.' The advertisements will be placed across Canada using locations found successful in previous trials to rapidly recruit participants (e.g. Google AdWords).
