Eligibility
Inclusion criteria
Inclusion criteria: 1. Adolescents aged between 18 and 24 years, either sex; 2. Adolescents report heavy drinking in the past 6 months. Heavy drinking is based on measures of heavy alcohol use and binge drinking and differs according to adolescents’ sex. Heavy alcohol use is defined as alcohol consumption exceeding the Dutch National Health Council for low-risk drinking – a mean consumption rate of more than 14 (females) or 21 (men) glasses of standard units of alcohol per week. Binge drinking is defined as drinking 5 of more glasses of standard units of alcohol on one drinking occasion at least once per week; 3. Adolescents are in the (pre)contemplation stage of change; 4. Adolescents have daily access to Internet; 5. Adolescents sign informed consent.

Exclusion criteria: Adolescents who are problem drinkers, drinkers who show symptoms of alcohol abuse or dependence and/or receive treatment for drinking-related problems, will be excluded from participation.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The percentage of participants who drink within the normative limits of the Dutch National Health Council for low-risk drinking and thereby not exceeding a mean consumption rate of more than 14 (females) or 21 (men) glasses of standard units of alcohol per week and/or drink 5 or more glasses of standard units of alcohol on one drinking occasion at least once per week at 1 month and 6 months after the intervention. In addition, we will assess reductions in mean weekly alcohol consumption and frequency of binge drinking. | — |
Secondary
| Measure | Time frame |
|---|---|
| Ecological Momentary Assessment (EMA) will be employed both in the pre-test (one month before the intervention) and post-test from January until August 2011 with a final follow up in November 2011. Every Monday participants will report the number of standard glasses of alcohol they drank during each day of that week and report the frequency of binge drinking during the assessment period. In addition, we will assess attitudes, self-efficacy, subjective norms and alcohol expectancies. These alcohol-related cognitions will be included at baseline, immediately after the intervention, and 1 and 6 months after the intervention. A cost-effectiveness analysis will also be included at baseline and 1 and 6 months after the intervention. | — |
