Plain English Summary

Background and study aims
Drinkware is a charity that aims to change people’s drinking habits and help reduce alcohol abuse and the harm caused by drinking too much alcohol. This study looks at how well two different messages displayed on their website, one focusing on health risks and the other on how drinking too much alcohol can have an impact on personal appearance, do in encouraging people to do a self-assessment that gives them feedback on whether they are at risk of damaging their health or appearance and whether they then go on to seek help for their drinking habit.

Who can participate?
Anyone who uses the Drinkaware website. However, there will be a particular focus on analyzing data from women over 35 years as this group has been identified by Drinkaware as a priority target group.

What does the study involve?
People who visit the Drinkaware website between Monday 3rd November and Sunday 14th December 2014 are randomly allocated to see either a brief health risk or appearance alcohol awareness message via banner advertisement in a prominent central position on the website. If web users choose to click on this banner, they are taken to another webpage containing a second brief message reinforcing the banner advertisement and are encouraged to self-assess their drinking behaviour using an online test - the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) questionnaire. AUDIT-C is a 3-item tool designed to see if someone is drinking alcohol at levels that may lower or increase risk to health. After they have completed the AUDIT-C questionnaire, participants are directed to a webpage containing their AUDIT-C risk score feedback and an extended health risk focused or appearance focused alcohol awareness message. At the bottom of this page, participants are provided with 3 help-seeking options including a number of web links containing information and providing access to resources and tools to encourage then to reduce the amount of alcohol they drink.

What are the possible benefits and risks of participating?
The benefit of participating is the opportunity to access a range of tools to help moderate alcohol consumption and improved recognition of what constitutes problem drinking. There is a risk that individuals find out they are drinking too much and do not access any of the support materials.

Where is the study run from?
The Drinkaware website (UK)
