The aim of this book is to weave together the diverse threads of epidemiological research in schizophrenia into a single volume that captures the new and exciting themes that have been emerging over recent years. Diverse topics are juxtaposed to expose synergy and to reveal new avenues of work, while the power of the epidemiological method runs throughout the book. The sections correspond to different subdisciplines within epidemiology: social, genetic and developmental epidemiology, with additional sections for special and emerging issues relevant to the epidemiological study of schizophrenia. Despite the multiple authorship, we have tried to maintain a unified approach to epidemiological thinking throughout the book. Authors were asked to concentrate on findings that have been established through robust epidemiological investigation.

The book provides an overview of the current state of epidemiological knowledge and research in schizophrenia and is intended as a reference for those involved in research about schizophrenia or in clinical work with individuals who suffer from schizophrenia. We have placed much emphasis on findings that may elucidate the causes of this complex illness. No previous training in epidemiology is assumed and a glossary of epidemiological terms is included at the back of the book. The editors are based in the UK, the USA and the Netherlands and are all engaged in schizophrenia. We are very fortunate in having gathered together a talented and internationally respected group of contributors and we thank them for their enthusiastic participation.
