Deposit Data
One of the major goals of NAHDAP and NIDA is to support the analysis of existing data. Sharing of data also fosters the development and testing of new conclusions, as data collected for one purpose can be used to pursue inquiries not addressed by the original investigators. Indeed, depositing files produced from the analysis of existing data (link to NACJD Web site) is also encouraged.
Benefits of Archiving Data
Archiving data affords multiple benefits to the investigator:
The investigator's study is described on the NAHDAP Web site.
NAHDAP distributes the data and supporting documentation to interested users, freeing investigators from using their own time and resources to do so and permitting other researchers to reanalyze the data.
Once the data are archived and available, the investigator is no longer responsible for maintaining permanent backups of the data he or she collected.
The investigator and his or her colleagues can assist each other in future research projects by sharing the archived data and documentation over a wide variety of computer platforms.
How do I deposit data?
The ICPSR Web site provides a great deal of information on how to deposit data, including:
- General Information on Depositing Data
- Guide to Social Science Data Preparation and Archiving (PDF 1.5MB)
- Confidentiality and Privacy
- FAQs on Sharing Data
Restricted Use Data Sharing
NAHDAP welcomes data collectors to consult with our staff about best practices in archiving and disseminating restricted-use data. NAHDAP staff is also available to manage restricted-use data dissemination for data collectors. ICPSR has a series of procedures for disseminating restricted-use data. For more detailed information, see the ICPSR Bulletin article, "Disclosure Analysis at ICPSR" (PDF 1.6MB).
