title: The social causes of psychosis in North American psychiatry: a review of a disappearing literature.
abstract: OBJECTIVE
  To review the North American literature with respect to the role of social factors in the etiology of psychosis, including schizophrenia.
  
  
  METHODS
  Relevant publications were identified through a search of MEDLINE from 1966 to 2006. Identified studies and articles had to originate in Canada or the United States to be included in the review. Articles written prior to 1966 were identified by cross-referencing bibliographies and reference lists. Articles were considered relevant if they discussed ethnoracial or other social factors as being causal or contributing to the development of psychosis or schizophrenia.
  
  
  RESULTS
  The relation between the etiology of psychosis and such social factors as poverty, migration, and racial discrimination has been neglected in the North American psychiatric literature for the last 40 years. In Canada and the United States, there is a dearth of research on these issues: the study of social causes of psychosis has been replaced by a focus on the clinical encounter, in which clinician bias is presumed to be responsible for widespread misdiagnosis of psychosis in minority (mainly African-American) populations. The reasons for neglecting social causes of psychosis in the North American psychiatric literature are obscure but may have to do with the rise of genetic-biological paradigms in recent decades.
  
  
  CONCLUSIONS
  The neglect of social causes of psychosis in the North American psychiatric literature has been coincident with an increase in scholarly concern among European clinicians and researchers. Careful reading of the European literature may reveal helpful avenues for future investigation in the North American context. In addition, drawing on social science literature and methods may help to clarify mechanisms underlying poverty, migration, and racial discrimination that contribute to psychosis in vulnerable individuals and groups.
