Abstract [en]

Introduction & Purpose: Digital interventions for changing problematic alcohol use have shown small effect sizes in relation to control groups. A meta-analysis (Riper et al., 2014) found an overall effect size of 0.20, with slightly higher effect sizes of 0.23 for interventions with a human guide, compared to 0.20 for unguided interventions. This presentation describes five different interventions, from unguided low-intensity to high-intensity guided interventions, evaluated in separate randomized controlled trials (RCT). Methods: Target groups included internet help-seekers and university students, with hazardous drinking according to the Alcohol Use Disorders Identification Test (AUDIT), excessive drinking based on national public health guidelines, or diagnosed alcohol use disorder (AUD). Study 1 evaluated eScreen.se, offering minimal screening and personal feedback, and alkoholhjalpen.se, a self-help program, with 633 internetbased participants reporting hazardous drinking. Study 2 evaluated the PartyPlanner and Promillekoll smartphone apps with 1932 university students reporting hazardous drinking. Study 3 evaluated the TeleCoach skills-based app with 186 university students who drank excessively. For studies 1-3 assessment-only controls were comparison groups. Study 4 compared the unguided eChange 10-week program to a guided version with 80 internet-based participants having at least hazardous use. Study 5 with 166 participants compared the high-intensity ePlus 13-week program to the unguided eChange program in a 13-week version, and a small wait-list control group. Results: Studies 1-5 are compared with one another in terms of baseline characteristics and results. Although inclusion criteria varied, baseline AUDIT levels out of a maximum of 40 points for studies 1-5 respectively were 20.82 (SD 6.93), 10.55 (3.90); 13.46 (4.69); 21.00 (4.90) and 23.70 (1.40). Within-group and between-group results are compared, showing greater effects for more intensive interventions. Conclusions: Effects vary by target groups, severity levels and interventions, but it is clear that digital interventions contribute to reduced problematic alcohol use.
