What is NAHDAP?
The National Addiction & HIV Data Archive Program (NAHDAP) is a NIDA-funded data archive program that acquires, preserves, and disseminates data relevant to drug addiction and HIV research. By preserving and making available an easily accessible library of electronic data on drug addiction and HIV infection in the United States, NAHDAP offers scholars the opportunity to conduct analysis of existing data on major issues of social and behavioral sciences and public policy. NAHDAP also offers consulting services for researchers, including but not limited to, budgeting data deposition cost for the data management and sharing plan, guiding data preparation, and providing letters of support for grant applications.
Since its launch in 2009, NAHDAP has made over 500 studies available to the research community, including studies such as Monitoring the Future Study (MTF), Research on Pathways to Desistance, and the Population Assessment of Tobacco and Health (PATH) Study.
What type of data are accepted for data deposition?
NAHDAP accepts social and behavioral research data in addiction, or HIV and addiction and related outcomes. A wide range accepted can be accepted (e.g., quantitative, qualitative, and imaging). Visit the NAHDAP website for a full list of high-priority data.
- NIDA-funded studies (and others)
