A Longitudinal Investigation of Knowledge Brokering As a Mechanism - PowerPoint PPT Presentation

A Longitudinal Investigation of Knowledge Brokering As a Mechanism for Integrating Research Evidence into Health Policymaking Itzhak Yanovitzky, Matthew Weber, Nicole Gesualdo & Teis Kristensen Rutgers University

Knowledge Brokers A knowledge broker is an intermediary (an organization or a  person), that aims to develop relationships and networks with, among, and between producers and users of knowledge.

Knowledge Brokering In the public policy domain, knowledge  brokering is a dynamic activity that regulates the flow and exchange of policy- relevant information (i.e., about the problem, alternative solutions, and political climate) to and from policy actors who are not directly connected. Through their information behavior (e.g.,  sharing, withholding, filtering , and interpreting information), influence (reputation, authority), and carrying capacity, knowledge brokers dynamically Information Flow regulate the scope, nature, and speed in which policy-relevant information travels within the policy system.

Study Methodology Qualitative and quantitative content analysis of all Congressional  documents concerning public policies to decrease childhood obesity from 2000-2014 ( N ≈ 1,578 documents). All excerpts containing explicit reference to evidence were coded  for source, type, and context of evidence use, interpretation of evidence, and the purpose for which it was used (conceptual, instrumental, political, tactical, and symbolic). Network analysis (two-mode and one-mode) of suppliers and users  of research evidence was created based on the actors referenced in each document and was used for tracking the flow of research evidence among actors over time.

Conclusion Opportunities for knowledge brokering in the macro-level policy  context are not fixed or limited to particular actors; rather they emerge dynamically in the course of the policymaking process as a function of the interplay between individual actors’ agency (e.g., policy champions) and characteristics of the political environment in which they operate. Knowledge brokers can be most effective when they have the capacity,  motivation, and political opportunities to broker use of evidence. It is important to recognize that the scope, nature, and use of the  evidence engaged by policymakers is different at different stages of the policymaking process and that a better understanding of the factors that influence differential use is crucial for informing decisions about the content, format, and timing of research evidence dissemination efforts.
