- Registration Number
- NCT03601793
- Lead Sponsor
- Centre for Addiction and Mental Health
- Brief Summary
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.
- Detailed Description
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).

- Primary Outcome Measures
Name Time Method Drinks preceding week 3 and 6 months Change in the number of standard drinks consumed during preceding week from baseline
Heavy drinking days preceding week 3 and 6 months Change in the number of heavy drinking days during preceding week from baseline
- Secondary Outcome Measures
Name Time Method Alcohol Use Disorders Identification Test (AUDIT) Baseline, 3 month follow up, 6 month follow up Assessment of alcohol problems
DSM criteria Baseline The 11 DSM criteria of alcohol use disorders (yes/no)
Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) Baseline, 3 month follow up, 6 month follow up Assessment of alcohol consumption (the first 3 items in AUDIT)
EuroQol Group 5 Dimensions Five Levels (EQ-5D-5L) Baseline, 3 month follow up, 6 month follow up Instrument measuring five health-related quality of life dimensions. Each dimension has five levels ranging from no problems to extreme problems. The dimensions can be combined into an index value between 0 (lowest) and 1 (highest). In addition to the five dimensions, a visual analogue scale item allows participants to measure health outcomes that reflect the participant's judgement. Endpoints are labelled 'The best health you can imagine' (100) and 'The worst health you can imagine' (0).
Previously received treatment or help for alcohol concerns Baseline (treatment or help ever/in the past 12 months), 3 month follow up (treatment or help in the past 3 months), 6 month follow up (treatment or help in the past 3 months) Questions about what kind of treatment or help for alcohol concerns the participant has received previously
