Background/Aims: Most problematic alcohol users never seek professional help to reduce their use, and Web-based interventions might fulfill users' unmet needs for professional support. Methods: This randomized controlled trial compared two open Web-based interventions, one extended self-help program and one brief screening and feedback intervention, with an assessment-only control group. Participants were 633 Internet help seekers with at least hazardous alcohol use (Alcohol Use Disorders Identification Test, AUDIT >= 6 for women and >= 8 for men). Results: All groups reduced their alcohol use at 3-month follow-up (p < 0.001), remaining stable at the 6-and 12-month follow-ups (n.s.) according to AUDIT-C and AUDIT scores (intention-to-treat, ITT, analysis). Per protocol (PP) analysis, including only participants who accessed the interventions and also reported accessing additional outside interventions during the trial, showed that about 75% of extended self-help participants moved from probable dependence, harmful or hazardous use to lower alcohol use levels at 3- and 6- and 12-month follow-ups, compared to about 40-60% of brief intervention users and controls who accessed extra help (p < 0.05). Conclusion: ITT analysis suggested parity over time for all interventions, including assessment only, in reducing problematic alcohol use. In contrast, PP analysis suggested that cognitive- behavioral extended self-help in combination with other interventions was more effective in changing alcohol use than brief intervention or assessment only.
