The NIMH Epidemiologic Catchment Area program. Historical context, major objectives, and study population...

Area of Science:

• Psychiatric Epidemiology
• Mental Health Services Research
• Public Health Surveillance

Background:

• Previous psychiatric surveys had limited scope.
• The need for large-scale, standardized mental disorder data was identified.

Purpose of the Study:

• To describe the design and methodology of the National Institute of Mental Health's Epidemiologic Catchment Area (ECA) program.
• To establish a framework for studying mental disorders and service use across diverse populations.

Main Methods:

• Large-scale, multi-site epidemiological study.
• Utilized the Diagnostic Interview Schedule (DIS) for DSM-III diagnoses.
• Employed a one-year reinterview longitudinal design for incidence and service use data.

Main Results:

• The ECA program involved approximately 20,000 subjects across multiple sites.
• Collected data on the prevalence, incidence, and service utilization of mental disorders.
• Provided demographic data for community and sample populations in New Haven, Baltimore, and St. Louis.

Conclusions:

• The ECA program established a robust model for psychiatric epidemiology.
• The study's design facilitates the linkage of mental disorder data with health service use.
• Findings provide a foundation for understanding mental health needs and service delivery.
