National Comorbidity Survey: Baseline (NCS-1), 1990-1992 (Restricted Version) (ICPSR 25381)

Principal Investigator(s): Kessler, Ronald C., University of Michigan. Institute for Social Research. Survey Research Center

Summary:

The National Comorbidity Survey: Baseline (NCS-1) is a collaborative epidemiologic investigation designed to study the prevalence and patterns of disorders in the third and revised edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM III-R) as well as correlates of service utilization for these disorders. The NCS-1 was the first survey to administer a structured psychiatric interview to a nationally representative sample and was carried out in the early 1990s with a household sample of over 8,000 respondents. Diagnoses were based on a modified version of the Composite International Diagnostic Interview (the UM-CIDI), which was developed at the University of Michigan for the NCS-1. This restricted-use data collection contains the following geographic variables that can be linked to the public-use version of the data using the CASEID variable: Census State FIPS codes, Census County FIPS codes, and Census 5-Digit County-State FIPS codes. However, in order to help preserve the confidentiality of the data the frequency tables in the codebook have been suppressed.

Data Collection Notes:

Methodology

Sample:   Stratified, multistage area probability sample. The inclusion of respondents as young as 15 years, compared with the 18-year-old lower age limit found in most general population surveys, was based on an interest in minimizing recall bias of early-onset disorders. The exclusion of respondents aged older than 54 years was based on evidence from the Epidemiologic Catchment Area Study that active comorbidity between substance use disorders and nonsubstance psychiatric disorders is much lower among persons older than 54 years than among those aged 54 years and younger. The Part II NCS-1 survey was administered to a subsample of 5,877 respondents. The Tobacco Use Supplement was completed by a subsample of 4,414 respondents. The NCS-1 also includes a supplemental sample of students living in campus group housing and a nonrespondent survey.

Weight:   The data are not weighted.

Mode of Data Collection:   face-to-face interview, telephone interview

Response Rates:   The response rate was 82.6 percent.
