Psychosocial and biological aspects of acute brief psychoses in three developing country sites.

This study explored biological as well as psychosocial contributions to the incidence of acute brief psychoses in three developing country sites. The samples were taken from the five year follow-up data of the International Pilot Study of Schizophrenia sites in Ibadan, Nigeria and Agra, India, and from the Determinants of Outcome of Severe Mental Disorders rural Chandigarh site. Baseline narratives of the cases and controls were reviewed and rated for presence or absence of three exposures: fever, departure from or return to parental village (women), and job distress (men). Results showed an association between fever and acute brief psychosis in all three sites. There was an association between acute brief psychosis and departure from or return to the parental village among women in all sites, and among men, an association between job distress and acute brief psychosis was noted in Ibadan and Agra. These findings suggest that psychosocial and biological factors such as these three exposures merit further research to clarify their roles in the etiology of acute brief psychoses.
