This paper examines the contextual characteristics common to binge drinking occasions reported by college students. In addition, the study examines the influence of such contextual characteristics on alcohol-related problems experienced by students. Using random sampling and telephone interview methodology, 401 college students attending a large southern California university were surveyed by trained research staff. The interview protocol was based on the Core Survey and included context of use questions from the College Risk Assessment Guide. Results of stepwise multiple logistic regressions indicate that drinking with friends and events with food available protect against alcohol problems, while drinking events in which illicit drugs are available present higher risk for problems. Implications for future research and prevention are discussed.

This study examined the relationship between environmental characteristics and heavy episodic drinking by examining college students' last drinking events. For this study, 409 undergraduate students attending a large public university were randomly selected. Students were asked to report on their last drinking event within the 30-day period prior to being surveyed. There were 274 drinking events analyzed. Bivariate analyses and multiple logistic regression analysis were used to identify contextual factors predictive of heavy episodic drinking in specific drinking events. Drinking with friends, drinking beer and hard liquor, and having many people intoxicated at an event were predictive of heavy episodic drinking events. Dating events were protective of heavy episodic drinking. Implications for future research and prevention are discussed.

This paper presents data from a study that collected observational data, survey data, and breath samples to estimate blood alcohol concentrations (BrAC) from patrons attending 30 bars. The study examines: 1) drinking behavior and settings prior to going to a bar; 2) characteristics of the bar where respondents are drinking; 3) person and environmental predictors of BrAC change (entrance to exit). Purposive sampling of bars that cater to young adults gave a sample of 30 bars. Patrons were randomly selected from bars (n=839). Approximately half of the sample was female (48.7%). Nearly threequarters of participants reported drinking before attending the bar. Serving practices of the bars were observed; majority of bars served excessive amounts of alcohol in short periods of time. On average, those who drank before attending the bar had BrACs at approximately half the legal limit. Implications for responsible beverage service coupled with law enforcement strategies are discussed.
