Introductory comments

This special section presents four evidence-based practices that are currently being transported to community-based settings: Nurse-Family Partnership for infant health and development, Assertive Community Treatment for adults with serious and persistent mental illness, Oregon Therapeutic Foster Care for chronic juvenile offenders, and Parenting Wisely for caregivers of children with disruptive behavior. Although each model addresses a very different clinical population, their similarities in development, emphasis on fidelity and quality assurance, and use of dedicated organizations to support effective transport are noteworthy. Admirably, the intervention developers are taking the same care in crafting strategies to transport their models as they took in validating these clinical innovations. Such care is critical to increasing the probability that the intervention models will be transported to community settings with the fidelity needed to achieve intended outcomes.
