Variables and codebook

These pages include a codebook for all available variables from the NEO study.

Each variable is described with its format, labels and values. This information can be used to request the appropriate variables for data analysis. 

First, the codebook for the baseline data collection will be placed online (see menu on the right). In the near future, data collected with the first follow-up questionnaire or obtained through electronic patient records will be also added to the codebook. 

For further information on how to request a dataset from the NEO database, please read this page.
