The goal of this research was to describe the most common drinking situations for young adolescents (N = 1,171; 46.6 percent girls), as well as determine predictors of their drinking in the seventh and eighth grades. Middle school students most frequently drank at parties with three to four teens, in their home or at a friend's home, and reported alcohol-related problems including conflicts with friends or parents, memory loss, nausea, and doing things they would not normally do. Differences emerged in predicting higher levels of drinking on the basis of sex, race, grade, positive alcohol expectancies, impulsivity, and peer drinking. These findings suggest both specific and general factors are implicated in drinking for middle school students. Contextual factors, including drinking alone, in public places, and at or near school, are characteristic of the most problematic alcohol involvement in middle school and may have utility in prevention and early intervention.
