How do I get the TEDS-A Concatenated file?

The TEDS-A concatenated data file is now available for download. This public-use file is provided in an ASCII rectangular format with SPSS and SAS data definition statements. A SPSS System and ASCII tab-delimited files are also available. Please note that because of the size of the data file normally available Stata files and the SAS Transport s file were unable to be produced.

If you are unable to download the file in one of the available formats, SAMHDA can provide you with the file. You can obtain the entire data set or select a subset of cases and/or variables. We can make the files available to you through a special Web link where you can access them directly. This is the quickest and easiest way for you to get the data you request. However, we can send you a CD of the files as well.

Please email us the following information at samhda-support@icpsr.umich.edu

  1. Data File Delimiter (choose one of the following):

    None -- the preferred delimiter for analyzing the data using SAS, SPSS, or Stata.
    Blank -- one of two delimiters for using Excel, Access, or other similar software package.
    Comma -- another delimiter for using Excel, Access, or other similar software package.

  2. Type of setup file(s) (choose one or more of the following):

    SAS
    SPSS
    Stata
    DDI (XML)
    SDA (DDL)

  3. Cases: Please indicate whether you desire all cases or a subset of cases. One common example of a subset would be to request only those cases for a given state. You may also request more than one filter to define a subset (e.g., males in the 12-14 year old age group). Please refer to the TEDS codebook when considering filters. Please note that some variables, such as age, are categorized and therefore only allow for certain specific age ranges.

  4. Variables: Please indicate whether you desire all variables or a subset of variables. If you request a subset of variables, please refer to the TEDS codebook when choosing variables for the subset. We prefer that you make your requests using Variable Groups (e.g., CLIENT CHARACTERISTICS, SUBSTANCES OF ABUSE: ORIGINAL VARIABLES, etc.).

As soon as we get this information from you, we will begin to process your request. We will email you instructions on how to retrieve the file from the Web site.
