SPF Partnership for Success- Student Leaders Advocating for Youth - Children’s Hospital Los Angeles (CHLA) is proposing to implement the Strategic Prevention Framework – Partnerships for Success for Communities, Local Governments, Universities, and Tribes/Tribal Organizations (FOA No. SP-23-004), a project to build the capacity of local community providers and youth leaders to reduce the onset and progression of substance misuse and its related problems by supporting the development and delivery of community-based substance misuse prevention and mental health services. This project will focus on the community Northeast LA (NELA), one of the most densely populated and impoverished neighborhoods in Los Angeles. The primary strategies for this Strategic Prevention Framework grant will be 1) to build the capacity of a multi-sector coalition to engage in data informed community planning to reduce substance use and improve mental health in adolescents and young adults in the community; 2) to engage and train youth leaders at 2 charter high schools advocate for school based and community change. The goals of the project are 1: to prevent the onset and reduce the progression of alcohol, marijuana, and opioid use and their related harms among adolescents and young adults (AYA) in NELA and 2) to increase youth-led and youth-informed structural change efforts around substance use prevention efforts and mental health promotion in NELA. Objectives include: 1.1: By 9/29/29, community leaders, parents, and students will have a greater understanding of evolving community needs and service gaps around AYA substance use and mental health in the NELA by reviewing the results of a multi-sector/multi-method needs assessment; 1.2: By 9/29/29, 50 community leaders in NELA will have knowledge competency on the Strategic Prevention Framework (SPF) model and on effective prevention strategies for AYA; 1.3: By 9/29/29, CHLA staff will reach a minimum of 1,000 young people in NELA through community prevention activities or events, including substance use prevention and mental health education. 1.4: By 9/29/29 500 parents and caregivers will learn about the intersectionality of mental health and substance use and local mental health and substance use resources. 1.5: By 9/29/29, students in target schools will report a statistically significant reduction in alcohol, marijuana, and/or opioid use as compared to baseline as measured through annual school-based surveys. 1.6: By 9/29/29, students in target schools will know how to access mental health, substance use prevention, and overdose prevention resources. 2.1: By 9/29/29, CHLA staff recruits and trains 75 youth leaders for two advisory boards in NELA on substance use prevention, overdose prevention, mental health promotion, and SPF. 2.2: By 9/29/29, youth leaders, with CHLA support, will plan and implement a minimum of 3 large community prevention events and 10 school-based events to inform the school community on substance use prevention, overdose prevention, and mental health promotion 2.3: By 9/29/29, youth leaders, with CHLA support, will identify barriers to mental health and substance use prevention and advocate for 3 structural changes on their school campus and/or community to address those barriers with school leaders, local neighborhood councils, coalitions, and/or elected officials. We expect to provide education, training, and/or evidence-based services to an average of 325 parents, community leaders, young people, and youth leaders annually and 1,625 individuals over the course of the project. Based on community and school demographics, the youth served will be 80% Latinx, 9% Other, 3% White, and 1% African American.
