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 the plain (not annotated) booklets/questionnaires, as used in the original studies; and also annotated versions showing variable names and item coding, both for raw data and for analysis datasets. The general convention used in the annotated documents is to use blue type for raw data variables and coding, and red type for analysis dataset variables and coding. Some documents also contain green type, to show the markup coding used in raw data files from optical scans.
