An orientation for new researchers to key domains, processes, and resources in implementation science.

The growth of dissemination and implementation (D&I) research over the last decade has produced a wealth of theories, frameworks, methods, strategies, and resources to inform the translation of evidence into wider practice. This article seeks to frame and orient researchers from the behavioral sciences to the rapidly growing interdisciplinary field of D&I science. We describe five domains across D&I research and practice: context assessment and intervention selection, dissemination, adaptation, implementation, and sustainability. We also discuss evaluation and communication as critical processes to drive ongoing learning and improvement across the five domains. In each section, we include widely cited literature and resources that readers may use to orient themselves to the field, and identify areas that they may want to explore further. This article organizes major areas of D&I science focusing on key definitions, approaches, and commonly used resources. It provides an introduction to researchers new to this area on how to conceptualize and navigate the field of D&I science, with the ultimate goal of increasing the reach and impact of evidence-based interventions.
