REDCap (Research Electronic Data Capture) is a secure web application for building and managing online surveys and databases. While REDCap can be used to collect virtually any type of data, it is specifically geared to support online data capture for research studies and operations. REDCap enables rapid project development and provides users with advanced functionality, complete autonomy and control of a project, and direct exports to common statistical packages. REDCap surveys and databases provide a rich security model that can be used to ensure access controls suitable for a wide array of protected data classes. There is no usage charge of REDCap for current GW faculty, staff, students, and affiliates. In addition to GW users, individuals with InCommon federated identity may be added to REDCap projects as collaborators.
