This grant would set the foundation for grants for following the cohort of study children and teachers periodically to assess the preventive impact of the interventions on later substance abuse and on extending teachers' use of WD practices. This prevention research in Baltimore continues under the aegis of our Community and Institutional Board (see letters of support). This proposal involves a close institutional collaboration among the American Institutes for Research (AIR); Baltimore City Public School System (BCPSS); Morgan State University (MSU); the Oregon Social Learning Center (OSLC); the Prevention Science and Methodology Group (PSMG); the Johns Hopkins Bloomberg School of Public Health; and the Center for Academic and Reading Skills at the University of Texas-Houston.
