Alcohol Monitoring Anklet Reduces Binge Drinking

Alcohol consumption can lead to a variety of negative outcomes, one of which is violence. A large number of incarcerated individuals are serving sentences for involvement in violent alcohol-related crimes. In some countries, the rate of recidivism and alcohol consumption upon release is increasing, prompting the need for more intense and novel approaches at reducing drinking among offenders.

Although many techniques for monitoring alcohol use exist, such as ignition breathalyzers, urine tests and blood tests, they are not always cost effective or feasible. Further, offenders often find ways to falsify results. However, a new method is a transdermal test that measures how much alcohol one has consumed by assessing sweat. This technique involves placing a device on the ankle of the subject. The anklet then records and transmits data from the transdermal test. Even though this type of assessment cannot detect very low levels of blood alcohol, it can measure whether someone has consumed more than the legal limit.

Fergus G. Neville of the School of Medicine at the University of St. Andrews in the United Kingdom recently tested the validity of the anklet on a sample of 60 male college students. His goals were to see if the anklet encouraged students to abstain and if so, how it supported abstinence. Neville placed anklets on one group of participants (A) and instructed them not to drink. The second group (B) was also instructed not to drink, but did not wear anklets. The participants in the third group (C) wore anklets and were instructed to drink as usual. The anklets recorded data every 30 minutes over a two-week period.

At the end of the study, Neville found that the anklets contributed to abstinence as the group A participants consumed the least amount of alcohol. Group B participants reported drinking more than those in groups A or C and participants in group C had the highest levels of alcohol consumption. Neville said, “The results of this pilot study suggest that wearing a continuous alcohol monitor can support individuals who are trying not to consume alcohol.”

Focus groups revealed that participants felt the anklets underscored their commitment to abstaining, made them aware of being monitored, and even acted as a tool for resisting peer pressure in drinking situations. Neville believes that future work should examine the effectiveness of anklets for offenders on parole in order to increase their chances at sobriety and decrease future violent offenses.

    By and large I do think that this is something that can help a lot of people. It is a program that holds you accountable to someone else and it helps you to be aware of taking that drink and makes you realize that this might not be the wisest choice. Great idea. But then what happens when the anklet comes off? there has to be some kind of behavior modification training going along with this the whole time to ensure that when the accountability device ios no longer there you are still able to make those good decisions without it. I know that there are people who say oh I can do it, but that is kind oif like going to weight watchers meetings. You do fine as long as you know you have to go to those weigh ins every week but then once it comes to the maintenance part and you are doing it on your own, that’s when the hard part really begins. Please don’t get me wrong, I do think that this could be a wonderful start in the right direction for many people for whom drinking is a big problem. But let’s try to remember that this is only the start of the solution and not the end resolution and that most drinkers have a long way to go on that road of complete sobriety.

    Do you really think that this is going to be effective in the long term or just for the time that the anklet is worn?

    I would like to think that this is the answer we have all been searching for but for most problem drinkers the problems go so much deepr than just having an ankle bracelt on.

    If they want to drink enough then they are going to drink, and that need is going to surpass any kind of technology that they are supposedly bound by.

    So they didn’t like the whole monitoring thing?
    i can relate to that., I wouldn’t want to feel like someone was always looking over my shoulder either.
    But there are some people who need this constant watching, who need that person always monitoring them when they have shown time and again that they cannot be responsible enough to manage this on their own.
