National Comorbidity Survey Replication (NCS-R), 2001-2003 (ICPSR 189)

Principal Investigator(s):


The National Comorbidity Survey Replication(NCS-R) is a probability sample of the United States carried out a decade after the original 1992 NCS (NCS-1) was conducted. The NCS-R repeats many of the questions from the NCS-1 and also expands the questioning to include assessments based on the diagnostic criteria of the American Psychiatric Association as reported in the Diagnostic and Statistical Manual - IV (DSM-IV), 1994. The two major aims of the NCS-R were first, to investigate time trends and their correlates over the decade of the 1990s, and second, to expand the assessment in the baseline NCS-1 in order to address a number of important substantive and methodological issues that were raised by the NCS-1. The NCS-R is part of the Collaborative Psychiatric Epidemiology Surveys (CPES) data collection (see ICPSR20240). Data and documentation for NCS-R can be accessed through the CPES Web site.
