Plain English Summary
Background and study aims
Unhealthy alcohol use (alcohol consumption that is associated with varying degrees of risk to health, such as injury, trauma, physical, psychological or social harm) is a leading cause of illness and death among young adults. It is therefore crucial to develop preventive interventions targeting unhealthy alcohol use. Face-to-face brief interventions targeting alcohol use are considered effective in primary care settings, but young individuals tend to have limited contacts with the health care system and are therefore unlikely to receive any intervention. As a result, electronic brief interventions have been developed that can reach a broad population at a relatively low cost and potentially impact the public health system. Electronic screening and brief interventions (E-SBI) targeting alcohol use are effective among college students, but more evidence is needed in order to evaluate E-SBI designed for young individuals in other settings. There is also a lack of knowledge about the primary prevention effects of these interventions on, for example, moderate drinkers. The aim of this study is to evaluate the effectiveness of a proactive E-SBI providing personalized feedback and information on alcohol use and its consequences among young men in the general population, to determine how young men will use E-SBI to obtain information on alcohol use and its consequences, and to evaluate how young men perceive the use of Internet to deliver preventive interventions. We think that E-SBI will decrease later alcohol use and related consequences among individuals with unhealthy alcohol use, and will prevent the increase of alcohol use among individuals without unhealthy alcohol use.
Who can participate?
The study participants will come from a population-based sample of 20-year-old men recruited from among participants in the Cohort Study on Substance Use Risk Factors (C-SURF).
What does the study involve?
Participants will be randomly allocated to either receive electronic personalized feedback (intervention group) or to not receive feedback (control group), and will be followed up at 1 month and at 6 months. The electronic personalized feedback includes self-assessment of current alcohol use and consequences, personalized feedback on alcohol use, and general information on alcohol use and its consequences (i.e., factsheets). Participants who report unhealthy alcohol use are encouraged to modify their drinking habits, and are presented with the rationale for risks associated with their current use of alcohol. Participants have the opportunity to print their personalized feedback form, and are able to access a section containing general information on alcohol use and its consequences. Participants in the control group complete the same baseline assessment as do members of the intervention group, but neither receive personalized feedback nor have access to the general information section on the website. The approximate time to complete the baseline assessment is three minutes. All participants are asked if they think that the Internet is a suitable option for providing personalized information about substance use.
What are the possible benefits and risks of participating?
There are several benefits from this study. The direct benefits include improvement in drinking habits if E-SBI proves to be effective, and the assessments and other information that participants will receive as feedback might give them a heightened awareness of their drinking habits and encourage them to drink less alcohol. The major risk in this research is breach of confidentiality, but great effort have been made to minimize that risk as much as possible. Electronic interventions have no reported or known side effects. The possible risk of harm to participants caused by this study is limited; therefore the potential benefits outweigh any potential risks.
Where is the study run from?

Electronic alcohol screening and brief intervention (E-SBI) for young adults:a randomized controlled trial
It is hypothesized that E-SBI will decrease later alcohol use and related consequences among individuals with unhealthy alcohol use and will prevent the increase of alcohol use among individuals without unhealthy alcohol use.
