Multiple studies have evaluated technology-based CBT interventions for alcohol use disorders, most of which focus on problem drinkers/heavy drinkers, rather than those with alcohol use disorder. A six-week on-line cognitive-behavioral self-help intervention for adult problem drinkers showed promise in a randomized controlled trial (N=261) conducted in the Netherlands (Riper et al 2008). Participants who utilized the interactive self-help intervention (Drinking Less) reduced their drinking significantly more than participants who received an on-line psychoeducational brochure about alcohol use. Seventeen percent of those receiving the intervention reduced their drinking to levels considered low-risk in the Netherlands (no more than 20 g of alcohol per day) compared with 5.4 percent of those receiving the educational brochure.
