All Stars Core is a school-based drug abuse prevention program for 11 to 14 year olds from the United States. It focuses on five qualities that protect children from drug use: viewing drug use as uncommon and unacceptable to the peer group (norms); viewing drug use as interfering with future goals; commitment to avoid drug use; positive attention from parents; and feeling accepted at school. All Star Plus was recently developed with the goal of expanding the Core program to include the development of three competencies: goal setting, decision making, and skills to resist peer pressure resistance. Students either received All Stars Core, All Stars Plus, or were assigned to the non-treated control group. Both programs outperformed the control group; however, All Stars Plus was more effective in preventing drug use than All Stars Core. All Stars Plus was found to reduce alcohol use, drunkenness, cigarette smoking, marijuana use, and inhalant use. The Plus program appeared to have achieved these outcomes by improving norms, increasing persistence in pursuing goals, and by increasing attention from parents. (Contains 8 tables.)
