The Coalition For Health Promotion project will implement environmental prevention strategies in order to (1) reduce youth substance use, and (2) establish and strengthen collaboration among communities, community agencies, systems of care, educational institutions, and existing community coalitions as a means of reducing substance use among youth. The focus community is Youngstown, Ohio, which is located in the northeastern part of the State in Mahoning County. Youngstown is the largest urban area in Mahoning County. Specific census tracts targeted are 8019, 8020, 8021, 8022, and 8023, which are located on the South Side of town, encompassing portions of zip codes 44502, 44507, and 44511. Boundaries for this area are Market Street at Woodland Avenue to Indianola Avenue to Glenwood Avenue and back down to Woodland. Multiple risk factors exist within this community which increase the probability of youth substance uses and the manifestation of the six problem adolescent behaviors, such as extreme economic deprivation, low community attachment and community disorganization, family conflict, academic failure, availability of alcohol, and transitions and mobility, along with limited protective factors. The Strategic Prevention Framework and the Seven Strategies for Community Level Change are the methodological processes that will be utilized and are embedded in all program strategies and evaluation processes. The project will specifically focus on utilizing strategies contained in the 12 Month Action Plan to reduce alcohol and marijuana use among youth. Specific interventions utilized seek to change community norms, reduce access to substances, utilize and target the media, and engage in changing public policy. Enhancing the capability of the existing substance use prevention system to provide innovative service, and facilitating coordination of services among those who work closely with youth (prevention agencies, schools, community based agencies, faith based community, etc.) will be key a key component of programming. Strengthening families will also be targeted through strategies contained in the 12 Month Action Plan. Additionally, the project will implement environmental prevention strategies which will facilitate multi agency and systems collaboration, with the intent of enhancing the local substance use prevention system, the efforts of other local coalitions, community based organizations, educational institutions, and social service agencies, so that collectively we can utilize our professional expertise and resources to reduce youth substance use, improve system collaboration, and facilitate sustainability. The impact of this should be a healthier, safer community where youth thrive and do not succumb to substance abuse and other behavioral health disorders.
