The costs to RIOS Net for the CBPR elements of the TM/CAM study included personnel, travel and meeting support costs aimed at partnering with community stakeholders in each phase of the project. In the development stage, investigators met with community representatives to assess interest and gather feedback. During the study, outreach staff provided updates to community members and the investigators met with the CAB. Following the conclusion of the study, outreach staff disseminated results and solicited input for subsequent research activities in this area. It is important to note that costs associated with the first phase−community input in determining research agenda−were incurred prior to the start of the study. RIOS Net is fortunate to have other sources of funding to support outreach efforts but this may likely represent a challenge for other researchers. See Table 2 for a more detailed list of cost elements.
