A 3-year intervention project focused on preventing substance abuse, violence, gang violence, and truancy among K-12 students at the Chief Leschi School in Tacoma, Washington, a tribally controlled, urban school for high risk and adjudicated Native youth. This paper reports the elementary school results. The Positive Reinforcement in Drug Education (PRIDE) curriculum, a comprehensive plan that integrates school and tribal community efforts to address substance abuse, was enhanced by revising it for grades K-6 and integrating it with newly adopted essential learning standards. A series of teacher trainings was conducted to increase teacher effectiveness in dealing with violence and substance abuse by implementing social learning strategies with students across grade levels. Pre- and post-assessment included interviews with key staff and three sets of quantitative data: school attendance, behavior records, and six student questionnaires about tobacco and drug use and future intentions. Data for grades 4-6 showed a significant decrease in emergence of drug-using behavior and the existence of risk factors over the 3-year project. Reported rates of alcohol and drug use decreased significantly since the fall 1996 surveys, although they generally increased during each academic year in each grade level due to socialization effects. Data are presented on use of cigarettes, smokeless tobacco, and drugs and intentions of future drug use by grade, December 1996 through June 1999. (TD)
