Access to C2C data
UCI C2C data are freely available to all UCI researchers. Please click on the link below to request UCI C2C data. In some cases, approval from the UCI Institutional Review Board (IRB) may be required before data can be sent.
Conduct of studies using C2C data
Successful execution of a study involving C2C data will consist of
- Identifying the scientific goals of the study
- Constructing testable hypotheses that can be addressed using existing C2C data
- Constructing an analytic plan designed to achieve the proposed scientific goals of the study
- Determining the study variables, selecting the variables from the datasets in which they are stored, and merging the selected variables into one or more datasets for analysis
- Performing the statistical analyses of the data.

Ongoing studies data repository
After requesting and being granted access to C2C data, once finalized, the dataset will be sent to the researcher. Researchers may download the data to their desktop computer for use. While data are de-identified, by agreeing to use C2C data, researchers must store all data on a password-protected machine in a locked office. Access to C2C data is only permitted to those individuals listed on the data request form.
