In the informed consent documents, I promised the data would only be used by an approved research team. How can I now share my data with others?

Unless the informed consent document names the members of the research team specifically, an amended Institutional Review Board application that includes a plan for data protection and dissemination can be filed with the lead institution to define the research team. Restrictive informed consent documents may prevent the release of data in purely public releases, but do not preclude the possibility of a research team that is defined by a group of restricted- or limited-use contract holders. The research team may be defined as those persons known to the original researchers. In the case of restricted-use or limited-use contracts, the researchers using the data are known to ICPSR and to the original research team.
