This implementation guide is designed for community-based organizations interested in developing programs similar to Plain Talk, a neighborhood-based initiative aimed at helping adults, parents, and community leaders develop the skills and tools needed to communicate effectively with youth about reducing adolescent sexual risk taking. The guide is a companion to the Plain Talk Starter Kit, which describes strategies used in five Plain Talk sites and attempts to capture lessons learned in these communities. This guide offers detailed information about program components at each site which can be adapted to other initiatives. It also looks at the strategy behind the Plain Talk initiative. Seven sections focus on: "Plain Talk Overview"; "Description of Plain Talk Components";"Community Mapping Component"; "Walkers & Talkers Component"; "Home Health Parties Component"; "Performance Measures"; and "Technical Assistance and Performance Measures." A final section offers other resources (annotated contact information for key organizations and a sample self-assessment form for the implementing agency). (SM)
