The greatest difficulty in the incorporation of CBPR methods in PBRN research is clearly the cost. Communication and outreach with community representatives and groups incur inevitable time and monetary costs that are generally not provided for in the current research funding paradigm. The majority of PBRNs are challenged to assure sufficient stable infrastructure funding to maintain basic operations; the addition of these costs for expanded communication and outreach may be difficult to support. While there is no single solution to this problem, we believe that the increasing recognition of the importance of community engagement in the biomedical research process has begun to open up new channels for funding this engagement.1
