Addiction, 113(2):346-352.

Abstract

Background and aims Given the scarcity of alcohol prevention and alcohol use disorder treatments in many low and middle-income countries, theWorld Health Organization launched an e-health portal on alcohol and health that includes aWeb-based self-help program. This paper presents the protocol for a multicentre randomized controlled trial (RCT) to test the efficacy of the internet-based self-help intervention to reduce alcohol use. Design Two-arm randomized controlled trial (RCT) with follow-up 6 months after randomization. Setting Community samples in middle-income countries. Participants People aged 18+, with Alcohol Use Disorders Identification Test (AUDIT) scores of 8+ indicating hazardous alcohol consumption. Intervention and comparator Offer of an internet-based self-help intervention, ‘Alcohol e-Health’, compared with a ‘waiting list’ control group. The intervention, adapted from a previous program with evidence of effectiveness in a high-income country, consists of modules to reduce or entirely stop drinking. Measurements The primary outcome measure is change in the Alcohol Use Disorders Identification Test (AUDIT) score assessed at 6-month follow-up. Secondary outcomes include self-reported the numbers of standard drinks and alcohol-free days in a typical week during the past 6 months, and cessation of harmful or hazardous drinking (AUDIT < 8). Analysis Data analysis will be by intention-to-treat, using analysis of covariance to test if programparticipants will experience a greater reduction in their AUDIT score than controls at follow-up. Secondary outcomes will be analysed by (generalized) linear mixed models. Complier average causal effect and baseline observations carried forward will be used in sensitivity analyses. Comments If the Alcohol e-Health program is found to be effective, the potential public health impact of its expansion into countries with underdeveloped alcohol prevention and alcohol use disorder treatment systems world-wide is considerable.
