The diagnosis and psychopathology of schizophrenia in New York and London

Abstract

The Cross National Project for the Study of the Diagnosis of Mental Disorders in the United States and the United Kingdom began a series of studies in 1965 which are still continuing. This report reviews only those aspects of the work of this project that bear on the diagnosis and psychopathology of schizophrenia and that were completed mainly in the period 1965-70. Those studies were limited to recognized patients aged 20 to 59 years and their informants who were already in contact with a public mental hospital.
