"Research shows there is a spike in alcohol-related consequences that occur in the first few weeks of the semester, especially with college freshmen," said Michael J. Cleveland, research associate at the Prevention Research Center and the Methodology Center. "If you can buffer that and get beyond that point and safely navigate through that passage, you reduce the risk of later problems occurring."
The researchers tested two different methods of intervention on incoming freshmen -- parent-based intervention and peer-based intervention. Cleveland and his colleagues found that students who were non-drinkers before starting college, and who received the parent-based intervention, were unlikely to escalate to heavy drinking when surveyed again during the fall semester of their first year.
Students who were heavy drinkers during the summer before college were more likely to transition out of that group if they received either parent-based intervention or peer-based intervention. However, if a heavy-drinker received both interventions, there was no enhanced effect.
Cleveland reported online in Psychology of Addictive Behaviors that 8 percent of the incoming freshmen were heavy drinkers the summer before starting college. The researchers surveyed the students again during the fall semester and found 28 percent of the freshmen now drank heavily.
The results of the study were based on a study of 1,275 high-risk matriculating college students originally conducted in 2006 by Rob Turrisi, professor of biobehavioral health. Turrisi and his colleagues randomly assigned students to one of four intervention groups -- parent-based intervention only, peer-based intervention only, both parent- and peer-based intervention or no intervention -- and then surveyed the students on their drinking behaviors the summer before they entered college and then again during their first fall semester.
The parent-based intervention involved parents receiving a 35-page handbook outlining how to discuss the issue of alcohol and how to relate to their college student. Parents were asked to fill out an evaluation of the booklet, which also served as a measure to determine how many parents read the material. All parents completed the evaluations.
For peer-based intervention, subjects met one-on-one with a trained peer facilitator once within the first two weeks on campus. The meetings were 45 to 60 minutes long and included "perceived and actual descriptive norms for drinking, drinking consequences, alcoholic caloric consumption and hours of exercise required to burn those calories," the researchers report.
All students included in the survey were former high school athletes, chosen because this group is considered at high risk for heavy alcohol use and its consequences, which include risky sex, driving drunk and personal injury or death.
In the new investigation, Cleveland and his colleagues approached the study differently. Rather than focusing on average levels of drinking -- peak blood alcohol content, drinks per weekend and drinks per week -- Cleveland reanalyzed the data using a person-centered approach to determine students' patterns of drinking as well as how the students responded to intervention. This allowed the researchers to examine how drinking patterns varied throughout the week as well as how the interventions could be linked to students' transitions from one sub-group to another.
"We found four sub-groups of drinkers, which is an important advance to understanding different types of drinking that were present in this college sample," said Cleveland.
The sub-groups included non-drinkers, who did not report drinking alcohol at all; weekend non-bingers, who tended to only consume alcohol socially on Fridays and Saturdays; weekend bingers, who were likely to report binge drinking and getting drunk in the past month on Fridays and Saturdays; and heavy drinkers, who reported drinking every day of the week, most notably Thursdays.
Although neither intervention strategy appeared to influence the weekend drinkers, whether bingers or non-bingers, the intervention effects on the nondrinkers and heavy drinkers were promising, said Cleveland.
"From here we may be able to tailor the intervention to different types of students, identifying those students who are at different types of risk," said Cleveland. "By figuring out a way to match the intervention to the individual you can also maximize your resources for intervention."
Cleveland is continuing this work by replicating the results among another sample of college students and is also using the same methods to study the drinking behaviors of young adults who are not attending college.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
