Notes

  • The ABCD Data Dictionary should be used to view administrative (non-item) variables, precedents for validation, and to further explore total and subscale score calculation.
  • Item and subscale total variables were copied directly from the ABCD Data Dictionary.
    • A blank in any cell indicates that measure was mentioned in the ABCD Protocol by Wave PDFs or Release Notes, but could not be located in the Data Dictionary.
  • The Flanker Task was included under the NIH Toolbox on the PDF protocol, but was listed as a separate cognitive task in the data dictionary.
  • The RAVLT Delayed Recall task was listed as distinct in the PDF protocol, but not in the online data dictionary.
