Codebook: VAULT Data Codebook

This codebook contains the information needed to understand the variable naming conventions and structure for the VAULT dataset from the larger Longitudinal Assessment of Late Talking Toddlers project. Information is available for all timepoints. Two adjunct documents are also available for this codebook, including 1) a codebook guide with additional information on the project, data collection, protocol, and timeline, and 2) a code sample describing procedures that were used to generate the reported D-scores as well as code for transforming the data for easier use for certain types of analyses.
