Featured Article: Preventing High-Risk Collegiate Drinking

Featured Article
In a new article in the journal Psychology of Addictive Behaviors, Michael Cleveland and his co-authors use latent transition analysis (LTA) to examine alcohol use among 1,275 high-risk, first-year college students. Alcohol use was measured during the summer before entering college and the students' first semester of college. Seven indicators of alcohol use were used in the LTA models. The analysis identified four patterns of drinking at both times: nondrinkers, weekend non-bingers, weekend bingers, and heavy drinkers. Researchers also examined the effects of parent- and peer-based interventions designed to prevent increased drinking. The results indicate there is value in considering multiple dimensions of alcohol use within a person-centered approach. That is, differential treatment effects were found across baseline drinking levels, suggesting the benefit for tailored intervention programs to reduce high-risk drinking among college students.
