Research and action for bridging science and practice in prevention.

There is a well-known gap between science and practice. To address this gap in the areas of Child Maltreatment (CM) and Youth Violence (Y/V), the Division of Violence Prevention (DVP) at the Centers for Disease Control and Prevention (CDC) embarked on a Dissemination/Implementation (D/I) planning project. The project was aimed at identifying better ways to connect research and practice through reviews of the literature as well as through discussions with experts on violence prevention and research utilization. This introductory article sets the stage for the rest of the special issue by defining terms, providing a rationale for the planning project, describing the planning process, and summarizing what is to come in the rest of the issue.
