Abstract
|
|
|
Epidemiology has usually been associated with epidemics of infectious diseases, and recently with prevalent chronic illnesses. As for psychiatry, it has been discussed almost exclusively within context of community surveys. Psychiatric epidemiology, based on community, has been greatly advanced owing to the development of operational criteria of psychiatric disorders and of diagnostic interview instruments such as DIS and CIDI, which could be administered by lay interviewers. In this article the authors described basic concepts, methodology, and history of psychiatric epidmiology.
In addition brief introduction of width of scope and utility of psychiatric epidemiology were explained. The rates, especially the prevalence rather than incidence, and risk ratio are basic concepts in epidemiology. Various kinds of designs and methods of psychiatric epidemiology have also been described. The reliability of the survey results are largely dependent on how valid the interview instruments are, and how much representative the selected samples are. Diagnostic validities will get higher through the recent advances in genetics, neuroimaging and neurobiology. Devlopment of the new methods to improve cost-effectiveness in community surveys in psychiatric epidemiology are needed.
