The Miami Youth Development Project (YDP) had its beginnings in the early 1990s as a grassroots response to the needs of troubled (multiproblem) young people in the community (Arnett, Kurtines, & Montgomery, 2008, this issue). YDP is an important outcome of efforts to create positive youth development interventions that draw on the strengths of developmental intervention science outreach research in the development of community-supported positive development programs (i.e., an approach that focuses on meeting community needs as well as youth needs by generating innovative knowledge of evidence-based change intervention strategies that are feasible, affordable, and sustainable in "real world" settings, (Kurtines, Ferrer-Wreder, Cass Lorente, Silverman, Montgomery, 2008, this issue). Now completing its second decade, YDP represents an effort to bring together a more empowering model of knowledge development for research involvement in the community, a nuanced and contextualized notion of youth and their development, and methodologies that richly reflect rather than reduce the experiences of the young people whose development the authors seek to promote.
