Although some twins in the CTS participated in Learning Center projects prior to the CADD, the CADD represented the first large-scale project with the full “CTS” sample. The CTS went on to complete assessments as part of multiple other studies at IBG.

Some subsetted files are provided here for ease of access, but please see the Wiki pages for these other studies for more information.

You may need additional permissions to download these files. Please contact Daniel.Gustavson@Colorado.edu if you are having trouble.
