Collaborative Psychiatric Epidemiology Surveys (CPES), 2001-2003 [United States] (ICPSR 20240)

Released/updated on: 2024-02-28
Geographic coverage: United States
Time period: 2001-01-01--2003-01-01
The Collaborative Psychiatric Epidemiology Surveys (CPES) were initiated in recognition of the need for contemporary, comprehensive epidemiological data regarding the distributions, correlates and risk factors of mental disorders among the general population with special emphasis on minority groups. The primary objective of the CPES was to collect data about the prevalence of mental disorders, impairments associated with these disorders, and their treatment patterns from representative samples of majority and minority adult populations in the United States. Secondary goals were to obtain information about language use and ethnic disparities, support systems, discrimination and assimilation, in order to examine whether and how closely various mental health disorders are linked to social and cultural issues. To this end, CPES joins together three nationally representative surveys: the NATIONAL COMORBIDITY SURVEY REPLICATION (NCS-R), the NATIONAL SURVEY OF AMERICAN LIFE (NSAL), and the NATIONAL LATINO AND ASIAN AMERICAN STUDY (NLAAS). These surveys collectively provide the first national data with sufficient power to investigate cultural and ethnic influences on mental disorders. In this manner, CPES permits analysts to approach analysis of the combined dataset as though it were a single, nationally representative survey. Each of the CPES surveys has been documented in a comprehensive and flexible manner that promotes cross-survey linking of key data and scientific constructs.

National Comorbidity Survey: Adolescent Supplement (NCS-A), [United States], 2001-2004 (ICPSR 28581)

Released/updated on: 2023-11-16
Geographic coverage: United States
Time period: 2001-02-01--2004-01-01

The National Comorbidity Survey Replication Adolescent Supplement (NCS-A) was designed to estimate the lifetime-to-date and current prevalence, age-of-onset distributions, course, and comorbidity of DSM-IV disorders in the child and adolescent years of life among adolescents in the United States; to identify risk and protective factors for the onset and persistence of these disorders; to describe patterns and correlates of service use for these disorders; and to lay the groundwork for subsequent follow-up studies that can be used to identify early expressions of adult mental disorders.

The core NCS-A interview schedule was an adaptation of the World Health Organization Composite International Diagnostic Interview (CIDI). NCS-A also administered the non-verbal subtest (Matrices subtest) of the Kaufman Brief Intelligence Test (K-BIT).

In addition to interviewing adolescents, information was collected from a parent or a parent surrogate to obtain an additional perspective on the adolescent's mental health and its correlates. Information from parents focused on the five adolescent disorders for which previous methodological research has most consistently shown that parental reports are important for making diagnoses: attention-deficit/hyperactivity disorder, conduct disorder, oppositional defiant disorder, major depressive episode, and dysthymic disorder.

Demographic information collected by NCS-A includes age, citizenship status, country of birth, criminal history, ethnicity, grandparents' country of birth, language(s) spoken in the home, parents' country of birth, race, religion, and sex.

The data collection contains six data files: (1) data for the adolescent household and school respondents; (2) data for the parents who responded to the long self-administered questionnaire; (3) data for the parents who responded to both the long self-administered questionnaire and short telephone interview; (4) diagnostic variables derived from the data collected from the adolescents and parents; (5) K-BIT scores normed to the NCS-A adolescent sample; and (6) raw K-BIT data.

National Comorbidity Survey: Baseline (NCS-1), 1990-1992 (ICPSR 6693)

Released/updated on: 2008-09-12
Geographic coverage: United States
Time period: 1990-01-01--1992-01-01
The National Comorbidity Survey: Baseline (NCS-1) was a collaborative epidemiologic investigation designed to study the prevalence and correlates of DSM III-R disorders and patterns and 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. The survey was carried out in the early 1990s with a household sample of 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 for the NCS-1. 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.

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

Released/updated on: 2023-11-06
Geographic coverage: United States
Time period: 1990-01-01--1992-01-01
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, Census 5-Digit County-State FIPS codes, and Census 11-Digit State-County-Tract FIPS codes. However, in order to help preserve the confidentiality of the data the frequency tables in the codebook have been suppressed.
