Substance Abuse and Mental Health Data Archive (SAMHDA)
Tutorial

SAMHSA's Office of Applied Studies provides public use files from its major data collection systems for on-line analysis. No personal identifiers are available from OAS data systems. These public use files are archived in the Substance Abuse and Mental Health Data Archive (SAMHDA). OAS established this on-line data analysis system to provide ready access to substance abuse and mental health research data. We share these data with researchers, academics, policymakers, service providers, and others to provide greater understanding of substance abuse and mental health problems and the impact of related treatment systems and, ultimately, to promote more effective prevention and treatment programs.

Overview of the SAMHDA System and Examples of Analyses

• Substance Abuse and Mental Health Data Archive (SAMHDA) brochure (PDF format, 396 KB)

• The DASIS Report:  Analyzing TEDS Using the New Graphing Features of the Online Data Analysis System (DAS)

• The DASIS Report:  Quick Statistics -- State level data on substance abuse treatment facilities and admissions

• The DASIS Report:  Protecting Confidentiality in TEDS: provides the rationale and procedures used for disclosure analysis.

• The DASIS Report:  Introducing Quick Tables: SAMHSA's Substance Abuse and Mental Health Data Archive (SAMHDA) recently added a new component to its online analysis capabilities called Quick Tables.  Quick Tables allows users to produce analytic tables by choosing variables from Drop-down menus.   This report provides an example showing the six easy steps to use Quick Tables to analyze any of the Treatment Episode Data Set (TEDS) files.

• The DASIS Report:  Graphing Multi-year Analyses of TEDS illustrates how trends in substance abuse treatment admissions from multi years can be analyzed, using heroin as an example.  SAMHSA's online data analysis system can provide percentages of substance abuse treatment admissions in each region, trends from 1995 to 2000, statistical testing, and various graphs of the results.  

• The DASIS Report:  Analyzing Geographic Areas Within TEDS:  illustrates how you can examine characteristics of substance abuse treatment admissions and compare various geographic areas.  The TEDS data can be analyzed using five types of geographic identifiers:  (1) metropolitan area, (2) State, (3) Census Region, (4) Census Division, and (5) State indicator to compare one State to all others combined.

• The NHSDA Report:  Finding Specific Variables in the NHSDA:  provides an overview of the SAMHDA search tool, a new feature that searches the question text, the variable labels, and value labels to find the variables of interest.  In addition, the report provides search tips  and examples of the variable level search utility, using SAMHSA's 2001 National Household Survey on Drug Abuse (NHSDA).

• The NHSDA Report:  Accessing and Analyzing the NHSDA Online:  helps with analyzing NHSDA and other substance abuse data systems online using the Substance Abuse and Mental Health Data Archive (SAMHDA).

• The DASIS Report: Analyzing TEDS Online:  provides an example to illustrate the type of questions that can analyzed and the procedure to conduct the online analysis of substance abuse treatment data.
