New results from University of Washington researchers point to why some students drink more alcohol while abroad and suggest ways to intervene.
"We hear stories in the media and elsewhere about students going abroad, drinking too much and getting into trouble. But no one has ever measured this risky drinking behavior and there are no published studies of prevention strategies before they go abroad," said Eric Pedersen, a UW graduate student in psychology.
Like heavy drinking on campus, consequences of drinking while studying abroad can be mild, such as missed classes due to hangovers, or more severe, such as fights, injuries and regrettable sexual experiences. But heavy drinking while in a different country can present additional problems, including disrupted travel plans, promoting negative stereotypes of American students and even legal issues with a foreign government.
In the current issue of Psychology of Addictive Behaviors, Pedersen and co-authors report that students doubled how much they drank while they were away, upping their consumption from about four alcoholic drinks per week while at home to about eight drinks per week while they were abroad.
"We can't really say if this is risky drinking or not," Pedersen said. "This could be a drink a night – a glass of wine at dinner – over the course of a week." Or, these students could be binge drinking, imbibing four drinks on Friday nights, for example, and another four drinks on Saturday nights.
Most of the 177 survey participants were abroad for three to five months. About two weeks before the students left, they completed a pre-departure survey asking how many alcoholic drinks they consumed each week, how much they planned to drink while they were away and what their perceptions were of the drinking habits of others studying abroad. A month after they returned to campus, they completed surveys about how much they drank while abroad and how much they were currently drinking.
When students returned to campus, generally they lessened their alcohol consumption to their pre-trip levels. But those who drank the most while away returned home drinking more heavily than when they left.
"That speaks to how there may be lasting changes in drinking behavior," Pedersen said.
Pedersen's data also support the idea that students younger than 21, the legal drinking age in the U.S., take advantage of more lax drinking laws abroad. The underage students in his study nearly tripled their drinking, whereas students over 21 doubled their intake of alcohol.
Drinking behavior also differed according to where in the world the students studied. Those who went to Europe, Australia or New Zealand drank more heavily while they were abroad than those who went to Asia, Latin America, the Middle East or Africa.
"Students have misperceptions about drinking in different countries," Pedersen said. For instance, students may think "Germans drink all the time and that's what I'm going to do too," he said. Correcting those misperceptions before the students go abroad could decrease their alcohol consumption while traveling.
Similarly, students have misperceptions about how much other American students drink. They overestimate, and then may adjust their own drinking behavior to try to match what they think everyone else is doing, Pedersen said.
Pedersen and his co-authors recommend that prevention programs target students who are heavy drinkers and intend to drink heavily while abroad. Talking with these students before they travel could correct their misperceptions of their peers' drinking habits and those of residents in different countries, resulting in less alcohol intake.
"The study abroad experience presents both unique opportunities and unique risks for students," said Mary Larimer, director of the Center for the Study of Health and Risk Behaviors and associate director of the UW's Addictive Behaviors Research Center. Larimer is a co-author on the study and Pedersen's doctoral adviser. "Working with these students pre-departure is a terrific opportunity to help reduce their risks for drinking consequences while abroad, and may also help prevent difficulties when they return home," she said.
Pedersen is now looking into how study-abroad students pace their drinking during the week. "Our data generally shows that students drink moderately while abroad, but a subset of students drink more heavily and may begin to experience consequences abroad," he said.
The research was funded by the National Institute on Alcohol Abuse and Alcoholism. Christine Lee, UW research assistant professor in the department of psychiatry and behavioral sciences, was a co-author on the study.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
