National Addiction & HIV Data Archive Program
Data
Most of the datasets in the NAHDAP archive are raw data from surveys, interviews, and administrative records. They were originally gathered in research projects and for administrative purposes. NAHDAP preserves them because they have value for "secondary analysis" - that is, reexamining old data to address new questions or to employ new analytic methods.
Some datasets in the Archive have been used in published studies. You can see a bibliography of these studies by clicking on the "view related literature" link on each study's home page.
Please review Data Access to learn how to access the NAHDAP collection.
