The University of Minnesota School of Public Health developed Project Northland, a community-based alcohol use prevention program focused on 6th, 7th, and 8th grade students (Perry et al., 1996). Seeking to delay initiation of drinking and reduce the amount of drinking among youth, the program included three years of an in-school curriculum (which includes teacher training), parent participation in alcohol education activities, and student participation in non-school, peer-leader-planned, alcohol-free activities. Using a randomized experimental design, the evaluation, which occurred between 1991 and 1994, included 2,400 students from 24 school districts. Ninety-four percent of the sample was Caucasian American with American Indian students comprising the remaining 5.5% of the study population. After three years, compared to control groups, the intervention group drank monthly 20% less often and drank weekly 30% less often. Intervention students were also 27% less likely to drink or smoke cigarettes. For those in the intervention group who never drank before the implementation of the study, the rates of marijuana and cigarette smoking were 50% and 27% lower, respectively.
