abstract="AIMS: To test the efficacy of a web-based alcohol intervention with and without guidance. <br><br>DESIGN: Three parallel groups with primary endpoint after 6 weeks. SETTING: Open recruitment in the German working population. PARTICIPANTS: Adults (178 males/ 256 females, mean age of 47) consuming at least 21/14 weekly standard units of alcohol (SUA) and scoring ≥8/6 on the Alcohol Use Disorders Identification Test. INTERVENTION: Five web-based modules including personalized normative feedback, motivational interviewing, goal setting, problem solving, and emotion regulation over 5 weeks. One intervention group received an unguided self-help version (n=146) and the second received additional adherence-focused guidance by eCoaches (n=144). Controls were on a waiting list with full access to usual care (n=144). MEASUREMENTS: Primary outcome was weekly consumed SUA after 6 weeks. SUA after 6 months was examined as secondary outcome, next to numbers of participants drinking within the low-risk range, and general and work-specific mental health measures. <br><br>FINDINGS: All groups showed reductions of mean weekly SUA after six weeks (unguided: -8.0; guided: -8.5; control: -3.2). There was no significant difference between the unguided and guided intervention (P=0.37). Participants in the combined intervention group reported significantly fewer SUA than controls (B=-4.85, 95%-CI=-7.02 to -2.68, P<0.001). The intervention groups also showed significant reductions in SUA consumption after six months (B=-5.72, 95%-CI=-7.71 to -3.73, P<0.001) and improvements regarding general and work-related mental health outcomes after six weeks and 6 months. <br><br>CONCLUSIONS: A web-based alcohol intervention, administered with or without personal guidance, significantly reduced mean weekly alcohol consumption and improved mental health and work-related outcomes in the German working population.<br><br>This article is protected by copyright.
