An Overview of Dissemination and Implementation Science in Physical Activity and Health Promotion

Dissemination and implementation (D&I) science can be described as the scientific study of the strategies and mechanisms by which scientific evidence is disseminated and implemented in community or clinical settings to improve outcomes for a specified population. This paper provides an overview of D&I science as it relates to health and physical activity promotion. It provides definitions and specifications for D&I strategies and an overview of the types of theories, models, and frameworks used to advance this work. Finally, this review demonstrated the need for physical activity researchers to (a) test relationships between changes in D&I explanatory constructs and D&I outcomes; (b) determine the utility of D&I strategies, based on explanatory theories, to improve intervention reach, effectiveness, adoption, implementation, and maintenance; (c) develop strategies to take interventions to scale and reduce disparities; and (d) develop interventions and D&I strategies, in collaboration with those who would ultimately be responsible for implementation.
