What happens when your drinking mate stops drinking?

As the song goes, you might love to have a beer with Duncan – but what happens when Duncan, Carol, Kevin or Pam decide to give up drinking?

Researchers at the University of Adelaide are looking to speak with people whose loved ones or close friends have recently stopped or reduced their alcohol consumption.

Their stories will form part of a bigger study into the social experiences of people who decide to change their drinking habits.

"There are a number of compelling reasons for people to limit or abstain from alcohol, especially health reasons, and yet alcohol is ingrained in Australian cultural and social practices. This can make ceasing or reducing alcohol consumption a difficult behaviour to perform," says Ashlea Bartram, a PhD student with the University of Adelaide's School of Public Health.

The first part of Ms Bartram's study sought the views of people who have stopped or reduced their drinking, "but it's also important to capture the experiences of significant others", she says.

"How do they perceive their friend's or loved one's change in alcohol consumption, how does it affect them in social situations, how do they support or not support this change? These and many other questions will be key to better understanding the social shifts – both subtle and unsubtle – that occur when someone stops drinking," Ms Bartram says.

Ms Bartram says her study will help to fill a gap in current research.

"To date, there have been no studies that explore what close friends and family think when their significant other decides to turn down a drink, and how it might affect their own social situations involving alcohol.

"Our ultimate aim is to develop strategies to better support people who are making a change or hoping to make a change to their drinking habits," Ms Bartram says.
