REDCap:General - User Roles
REDCap allows a fine granular definition of user access rights. When adding a person to a project, you can either choose custom user rights, or you can define roles, e.g. a role that only allows data input or a role that only allows de-identified data export for analysis. As a general guideline, grant access to project members as needed according to their role in the project and according to any other definitions from ethical approvals, collaboration contracts, etc. that might apply.
