Project Northland is a multi-level intervention involving students, peers, parents, and community in programs designed to delay the age at which adolescents begin drinking, reduce alcohol use among those already drinking, and limit the number of alcohol-related problems among young drinkers. Administered to adolescents in grades 6-8 on a weekly basis, the program has a specific theme within each grade level that is incorporated into the parent, peer, and community components. The 6th-grade home-based program targets communication about adolescent alcohol use utilizing student-parent homework assignments, in-class group discussions, and a communitywide task force. The 7th-grade peer- and teacher-led curriculum focuses on resistance skills and normative expectations regarding teen alcohol use, and is implemented through discussions, games, problem-solving tasks, and role-plays. During the first half of the 8th-grade Powerlines peer-led program, students learn about community dynamics related to alcohol use prevention through small group and classroom interactive activities. During the second half, they work on community-based projects and hold a mock town meeting to make community policy recommendations to prevent teen alcohol use.
