NATIONAL COMORBIDITY SURVEY (NCS)
Description:
The National Comorbidity Survey (NCS) 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 was the first survey to administer a structured psychiatric interview to a nationally representative sample. This project also represents the U.S. contribution to the WHO World Mental Health initiative which consists of over 35 countries conducting mental health surveys using the same core set of measures to allow for cross national comparisons of the prevalence, severity and correlates of mental disorders as well as an overall determination of the global burden of mental disorders. NCS Replication survey (NCS-R) is being carried out in a new national sample of 10,000 respondents. This study was sponsored by National Institute of Mental Health, National Institute on Drug Abuse, and W.T. Grant Foundation.
