This data dictionary document provides a guide to variable names and descriptions for key variables and constructs in CTDA datasets.

There are two main “levels” of data/information that may be captured in CTDA variables:

• Study-level Data
  • Represent ‘metadata’ about the study context and design that are crucial for understanding and using IPD 
• Individual Participant-level Data (IPD)
  • Represent data (usually raw, item-level data) for each case/participant in a study
