About

Higher rates of psychosis are described in migrant population. Likewise, this populations could suffer several adversities during migration process that could lead to higher exposure to traumatic events and higher rates of posttraumatic stress disorder (PTSD). There is a growing evidence that trauma is associated with psychosis onset.

The aim of this research is to study the association between psychosis and traumatic events exposure/PTSD in immigrant population. Our hypothesis is that the higher incidence of psychosis described in immigrant population is associated to higher trauma exposure.

A case-control observational study is performed. Patients who presented at least one psychotic episode are recruited from acute and chronic units at "Parc Salut Mar" (Barcelona). Estimated total sample is 196 individuals. Trauma exposure is assessed by validated trauma scales. Known factors associated with psychosis are controled during the statistic analysis.
