ADDEP is a ready source of data related to disability and rehabilitation medicine in the United States. We provide data for use with statistical packages (SPSS, Stata, SAS, and R) and sometimes Excel, and for online analysis. Each dataset is accompanied by full documentation, such as codebooks, questionnaires, and user guides.

To access data files, users must login to ICPSR with a free ICPSR MyData account or an existing Google, LinkedIn, or Facebook account. Documentation files do not require users to log in.
