What resources are available through SAMHDA?
Documentation for studies consists of one or more data files and codebooks, as well as setup files for SPSS, SAS, and Stata. SAMHDA also provides a detailed description file for each study.
Many studies can be analyzed using the online Survey Documentation and Analysis (SDA) system. The SDA system allows users to conduct statistical analyses online without having to download data files or setup files. For more information on the SDA system, please consult the Online Analysis Using SDA page.
The Simple Crosstab/Frequency tool can be used for any study that is available for online analysis in SDA. This tool can be accessed from the Dataset(s) section of the study home page.
Some studies also have Quick Tables and Interactive Maps.
A select number of restricted-use data files can be analyzed using the Restricted-use Data Analysis System (R-DAS). The R-DAS allows researchers to produce frequencies and cross-tabulations, and export their results.
SAMHDA provides links to publications, including a searchable database of bibliographic citations for publications that are based on SAMHSA data.
