The Representativeness of Practiced-based Research Networks: The Case of the American Academy of Family Physicians National Research Network
Study Description and Methods
This project examined the degree to which AAFP NRN members were representative of the larger population of family physicians. The representativeness of NRN members was explored with respect to their self-reported clinical practices/behaviors and their knowledge and beliefs about selected clinical care issues.
This study consisted of analyses across five separate national surveys conducted between 2001 and 2004 by the AAFP NRN in distinct clinical areas (bioterrorism preparedness, hepatitis C, hyperlipidemia, pharyngitis, and immunization). Each survey collected data from NRN and non-NRN family physicians. Descriptive analyses and applicable tests were conducted on the survey data in comparisons between NRN and non-NRN family physicians. Additional analyses were also conducted to determine the degree of statistical comparability of AAFP survey respondents to the population of AAFP active members.
Specific Aims and Objectives
The aim of this study was to investigate the extent to which NRN physicians’ responses to survey items measuring their clinical beliefs and self-reported practice patterns differ from sampled AAFP active members.
This study was conducted from October 2004 through September 2005.

Key Findings and Publications
The AAFP NRN and AAFP membership differed on several demographic characteristics, but network members were overall more representative than not to the AAFP active membership in their self-reported clinical behaviors and related beliefs.
