Translating evidence-based HIV/STD prevention interventions and research findings into applicable HIV prevention practice has become an important challenge for the fields of community psychology and public health due to evidence-based interventions and evidence-based practice being given higher priority and endorsement by federal, state, and local health department funders. The Interactive Systems Framework (ISF) for Dissemination and Implementation and the Division of HIV/AIDS Prevention (DHAP) Research-to-Practice model both address this challenge. The DHAP model and the ISF are each presented with a brief history and an introduction of their features from synthesis of research findings through translation into intervention materials to implementation by prevention providers. This paper describes why the ISF and the DHAP model were developed and the similarities and differences between them. Specific examples of the use of the models to translate research to practice and the subsequent implications for support of each model are provided. The paper concludes that the ISF and the DHAP model are truly complementary with some unique differences, while both contribute substantially to addressing the gap between identifying effective programs and ensuring their widespread adoption in the field.
