The previous chapter described a prospective population cohort study as a prototype. By modifying one or another element of this prototype, this chapter constructs natural experiments, historical cohorts, and special exposure cohorts. To these three major variants a fourth is added—the clinical cohort—the purpose of which is to discover the determinants of the course and outcome of a disorder. This variant, close kin to the etiologic cohort, has been prominent in psychiatric epidemiology. The chapter gives an account of a cohort study that has evolved over a period of more than fifty years. Finally, it introduces a data set, the Prenatal Determinants of Schizophrenia Example (PDSE) study, for illustration in this and other parts of the book.
