TEDS Booklets and Questionnaires

This page contains convenient links to all the booklets and questionnaires (and some other study documents) that are available in pdf form within this data dictionary. Clicking on each link will open the pdf document in a new browser window.

The documents linked below include, in the second column, the plain (not annotated) booklets/questionnaires, as used in the original studies; and also, in the third column, annotated versions showing variable names and item coding, both for raw data and for analysis datasets.

Where indicated, there are separate documents showing dataset coding and raw data coding. Where this is not indicated, both dataset coding and raw data coding are annotated within the same document. In all these documents, the general convention is to use blue type for raw data variables and coding, and red type for dataset variables and coding.
