Children vulnerable to psychopathology: the Stony Brook high-risk project.

The study of children at risk for the development of schizophrenia is a promising research strategy for increasing our understanding of the etiology of schizophrenia. This paper describes the methods and procedures of such an investigation. Three groups of children are being followed: those who have a schizophrenic parent, those who have a depressive parent, and tose whose parents have no psychiatric history. There are three major foci of our assessment procedures. First, the patient, spouse, and family environment are examined. Second, the children are assessed in school from the vantage point of both peers and teachers. Finally, the children are tested with several laboratory measures of cognitive processes, attention, emotional responsivity, and social interaction.
