The Prevention and Early Intervention (PEI) Plan is a required component of the California Statewide Mental Health Services Act (MHSA). The Los Angeles County Department of Mental Health (LADMH) contracted with WRMA to provide strategic planning, facilitation, and support services to assist in the development of its PEI plan. This included assisting in designing and guiding the planning process. It also involved evaluating and enhancing the capacity of LADMH community partners to engage in the planning effort. WRMA was responsible for designing the interviews, focus groups and community forums, organizing and managing all aspects of the site-specific details, conducting and facilitating the events, providing support in Los Angeles County threshold languages, recording and transcribing all events, and providing reports summarizing and analyzing the results. Subsequently, WRMA was responsible for developing the protocols for selecting PEI programs to be funded as part of the PEI plan and providing plan implementation and outcome evaluation services.
