The National Comorbidity Survey: Baseline (NCS-1), 1990-1992 Study Has Moved

The NCS-1, 1990-1992 study has been transferred from the SAMHDA archive to the National Addiction & HIV Data Archive Program (NAHDAP) Archive. NCS-1 data and documentation files can now be accessed through the NAHDAP and ICPSR General Archive websites. We apologize for any inconvenience this transition may have caused.

The National Comorbidity Survey: Baseline (NCS-1) investigated the prevalence and correlates of DSM III-R disorders, and patterns and correlates of service utilization for these disorders. Carried out in the early 1990s, the NCS-1 was the first survey to administer a structured psychiatric interview to a nationally representative household sample that resulted in over 8,000 respondents. Subsamples of the original respondents completed the NCS-1 Part II survey and Tobacco Use Supplement. Diagnoses were based on a modified version of the Composite International Diagnostic Interview (the UM-CIDI), which was developed at the University of Michigan. Drugs covered by this survey include alcohol, tobacco, sedatives, stimulants, tranquilizers, analgesics, inhalants, marijuana/hashish, cocaine, hallucinogens, heroin, nonmedical use of prescription drugs, and polysubstance use. Other items include demographic characteristics, personal and family history of substance use and abuse, substance abuse treatment, data on drug use including recency, frequency, and age at first use, problems resulting from the use of drugs, personal and family history of psychiatric problems, mental health treatment, symptoms of psychiatric disorders, mental health status, HIV risk behaviors, and physical health status.
