Introduction: the challenge of integrating research into practice.

The Introduction to this volume on the ways Healthy Families America (HFA) integrates research, theory, and practice describes nine articles that offer a contemporary snapshot of HFA research and practice, including four empirical articles presenting research and practice at the state, multi-state, or national level and the most comprehensive summary of HFA outcomes. It contrasts the history of child abuse prevention with progress in the fields of substance abuse and violence prevention. It presents arguments underscoring the critical importance of the researcher-practitioner relationship and the need for an iterative model of action research. It examines implementation and action research challenges, illustrates lessons learned, and recommends ways to strengthen HFA and guide the next phase of child abuse prevention.
