The variables I want to examine have been removed or modified. How do I gain access to them?
Given the sensitive nature of the data archived in SAMHDA, great lengths are taken to ensure that respondent identity is protected. For this reason, variables that pose an identification (or disclosure) risk are modified or removed from public-use data files.
A select number of restricted-use data files can be analyzed using the Restricted-use Data Analysis System (R-DAS).
Access to confidential data may be made available through the Data Portal for approved researchers. Completion of an application process and project approval are required for access to the Data Portal. Data Portal application periods are announced through the SAMHDA email list.
