The Peace Partnership For Success project will fund culturally appropriate, sustainable prevention strategies to be piloted by sub-recipients in six (6) selected Guam Department of Education (GDOE) primary and secondary schools, leveraging existing partner services to provide training and expertise and collaborating closely with GDOE to expand their in-school capacity and effectiveness to reduce alcohol and tobacco/nicotine offenses by students ages 9 to 20. Up to 200 student offenders will be served at the selected school sites by sub-recipients in years 2 through 4 (800 total) by evidence-based substance use prevention, intervention and referral programs proven to reduce alcohol and tobacco/nicotine use. This will be supplemented by a tobacco education and awareness campaign at all 25 elementary schools focused on fourth and fifth graders, middle and high schoolers by the Department of Public Health and Social Services Tobacco Control Action Team. Additionally, GDOE personnel will receive the following training in the first two years of the grant: 40 trained in Brief Tobacco Intervention; 10 trained in Fresh Start tobacco cessation training; 20 trained in evidence-based clinical screening tool(s) to effectively refer substance use offenders to behavioral health and/or substance use treatment; 40 trained in Brief Intervention (for alcohol and other drugs) to provide information to student offenders identified to be at low risk for repeat alcohol use, their parents and selected elementary, middle and high school staff on the risks of alcohol and other substance use, services and resources available to reduce use and recidivism rates; and 10 clinical personnel will be trained in the selected in-school evidence-based treatment program by GBHWC Drug and Alcohol for students at medium to high risk of alcohol abuse. The goals to be addressed by these strategies are: 1) To increase the number of youth in selected elementary and secondary schools who receive services for their alcohol and/or tobacco/nicotine substance use disorders through early identification and intervention by strengthening partnerships with Guam Department of Education (GDOE); 2) To effectively assess students with alcohol and tobacco/nicotine offenses to determine level of risk for use and/or co-occurring issues that contribute to substance use and misuse; 3) To increase the capacity of GDOE to provide tobacco education and tobacco cessation services to students with tobacco/nicotine offenses; 4) To increase the capacity of GDOE to provide alcohol education services and substance use treatment services to students with alcohol offenses; 5) To reduce alcohol and tobacco/ nicotine offenses by student offenders in targeted elementary and secondary schools and reduce risk factors and increase protective factors related to the problem of substance use; and 6) To increase perception of harm on effects of alcohol and tobacco/nicotine use by students.
