In the previous chapters we discussed specifications of research questions, general study designs, and study size. The next step in developing a study proposal is to create a practical plan for how to find and enroll participants or other observation units. It is important to be clear about what particular characteristics are needed (inclusion and exclusion criteria), how to identify an appropriate number of participants (recruitment, sampling, and eligibility screening), and how to get the necessary permissions to access secondary data or to obtain new information after informed consent and enrollment. The principles and guidelines for each of these tasks are described in this chapter (terminology in Panel 9.1), except that we devote a separate chapter (Chap. 16) to the management of the informed consent process.
