The Project MATCH Public Data Set is being released in three waves. The first wave includes the major variables used to test the trial's hypotheses (e.g., client matching attributes, treatment outcomes) and additional summary scale scores derived from the assessment instruments used in the trial. Data files are organized by content domain. Wave II files contain item-level (raw) data, also organized in terms of content domain. Wave III will consist primarily of data from the three year follow-up evaluation of clients in the trial's Outpatient arm. Wave II and Wave III data files will also include additional measures developed by trial investigators that were not available earlier.

Wave I of the Public Data Set is currently available. Users should familiarize themselves with the design and methods of this investigation, as well as the data set documentation prior to running analyses.

Waves II and III of the Public Data Set are not yet fully available, however, members of the Project MATCH Public Data Set User Group who demonstrate a strong and detailed rationale for use of specific data may submit a request to the Coordinating Center, by contacting Janice Vendetti or Frances Del Boca.
