In 1993 The Annie E. Casey Foundation made a substantial commitment to the goal of reducing adolescent pregnancy and sexually transmitted disease by investing in the design and development of the Plain Talk initiative. Plain Talk attempts to organize and mobilize community residents to change the attitudes and practices of adults, teenagers, and service providers to support the wider use of contraception and protection. The experiences of six Plain Talk communities, in urban neighborhoods in Atlanta (Georgia), Hartford (Connecticut), Indianapolis (Indiana), New Orleans (Louisiana), San Diego (California), and Seattle (Washington) were documented by Public/Private Ventures, the project's evaluator. This report describes the sites and their planning processes and the key issues arising during the implementation of Plain Talk principles. The six communities made substantial progress in the planning year, especially with regard to involving community residents. While the process of developing consensus varied, five of the six sites made real steps forward. The experiences of the initial year indicate that Plain Talk is a promising example of community involvement and mobilization as well as a useful vehicle for learning about implementation and community participation. Appendix A describes study methodology, and Appendix B explores characteristics of Plain Talk communities. (Contains nine references.) (SLD)
